Description

Technical Field

[0001] This invention relates to the field of silicon molten metal casting technology, and in particular to an intelligent casting method and system for industrial silicon. Background Technology

[0002] In the high-temperature refining industry, high-temperature liquid substances are refined in high-temperature furnaces. Usually, transportation equipment needs to be set up next to the high-temperature furnace to transport the high-temperature liquid substances out of the furnace. For example, in the silicon manufacturing process, silicon refining is involved. The high-temperature silicon water obtained from the refining process needs to be taken out of the refining furnace and put into a silicon bag. Then, the silicon bag is transported out to realize the transportation of the high-temperature silicon water. The silicon water is then transferred and poured into the casting tank of the ingot mold car to facilitate the solidification of the silicon water into blocks.

[0003] Currently, the industrial silicon casting process relies heavily on manual operation, with a low degree of automation and high requirements for equipment operation experience, making it difficult to meet the growing demand. Summary of the Invention

[0004] The purpose of this invention is to provide an intelligent casting method and system for industrial silicon, which intelligently controls the casting of molten silicon, saving manpower and resources; effectively controls the amount of molten silicon poured and the amount of casting, and visualizes on-site data.

[0005] According to a first aspect of the present invention, a smart casting system for industrial silicon is provided, comprising:

[0006] Obtain the position information of each burner nozzle on the furnace body within the tilting area of ​​the transport vehicle's transfer track, and generate a tilting position in the tilting area based on the position information;

[0007] When a start command is received, the carrier vehicle indicated in the start command runs to the tilting position to match. When it is detected that the carrier vehicle carrying the silicon bag has run to the corresponding tilting position, the furnace nozzle pours molten silicon into the silicon bag until the molten silicon pouring is completed.

[0008] The casting slot that is idle and first in the order on the ingot mold car is aligned with the casting position on the transfer track. The ingot mold car is adjusted until the casting position coincides with the flipping position on the transfer track.

[0009] The transport vehicle, after completing the pouring of molten silicon, runs towards the casting position. When the transport vehicle carrying the silicon bag reaches the turning position, the silicon bag is turned over and molten silicon is poured into the casting tank.

[0010] The real-time casting volume of the silicon ladle is detected. When the real-time casting volume reaches a preset value of interest, the tilting angle of the silicon ladle is detected. When the sum of the buffer amount corresponding to the tilting angle and the real-time casting volume reaches a preset casting standard value, the transport vehicle stops casting the silicon water into the casting tank.

[0011] Furthermore, "obtaining the position information of each burner nozzle on the furnace body within the tilting area of ​​the transport vehicle's transfer track, and generating a tilting position in the tilting area based on the position information" specifically includes:

[0012] Based on the position of the furnace body, a tilting area is divided on the transfer track; when the furnace nozzle of the furnace body is in the tilting area, the transport vehicle on the transfer track can receive the molten silicon tilted from the furnace nozzle;

[0013] Obtain the current rotation angle of the furnace body, and calculate the position information of each burner on the furnace body within the tilting area based on the initial position of each burner on the furnace body;

[0014] The location information is projected onto the dumping area, and the dumping position is generated based on the transfer track;

[0015] When the rotation angle of the furnace body changes, the tilting position is recalculated and generated.

[0016] Furthermore, "when a start command is received, the transport vehicle indicated in the start command moves towards the tilting position; when the transport vehicle carrying the silicon bag reaches the corresponding tilting position, the furnace nozzle pours molten silicon into the silicon bag until the molten silicon pouring is completed" specifically includes:

[0017] The start command is generated by the identification code of the transport vehicle selected by the staff and the drive command;

[0018] Obtain the identification code of the transport vehicle indicated in the start command, and call the corresponding transport vehicle to the tilting position according to the identification code;

[0019] When the carrier vehicle is detected to have reached the tipping position, the empty weight of the silicon bag is obtained, and a tipping command is sent simultaneously. The furnace nozzle corresponding to the tipping position pours molten silicon into the silicon bag carried by the carrier vehicle.

[0020] The total weight of the silicon pack when receiving the silicon water is detected, and the amount of silicon water poured out is calculated;

[0021] When the amount of water poured reaches a preset quantitative value, a stop pouring command is sent.

[0022] Complete the pouring of the silica water.

[0023] Furthermore, "identifying the casting slot that is idle and first in the sequence on the ingot mold car with the corresponding casting position on the transfer track, and adjusting the ingot mold car until the casting position coincides with the ladle-turning position on the transfer track" specifically includes:

[0024] Obtain the status information of each casting trough mounted on the ingot mold car; the casting trough is in an idle state if and only if the weight of the casting trough is within a threshold range;

[0025] Extract the casting troughs that are in an idle state and sort them according to the mounting order of the casting troughs on the ingot mold car;

[0026] Obtain the relative positional relationship between the ingot mold car and the transfer track, and calculate the casting position on the transfer track corresponding to the first casting trough;

[0027] Calculate the difference vector between the casting position and the ladle turning position, and drive the ingot mold car to move according to the difference vector so that the casting position corresponding to the first casting trough on the transfer track coincides with the ladle turning position.

[0028] Furthermore, "the transport vehicle, after completing the pouring of molten silicon, moves towards the casting position; when the transport vehicle carrying the silicon ladle reaches the ladle-turning position, a ladle-turning operation is performed on the silicon ladle to pour molten silicon into the casting tank" specifically includes:

[0029] The casting position is found to coincide with the overturning position. The casting position is obtained, and the transport vehicle that has completed the pouring of molten silica is driven to run towards the casting position.

[0030] When the transport vehicle carrying silicon packages is detected to have reached the package-flipping position, a package-flipping command is sent to activate the package-flipping device to perform the package-flipping operation on the silicon packages.

[0031] The flipping device flips the silicon package and pours the molten silicon into the casting tank.

[0032] Furthermore, the phrase "detecting the real-time casting volume of the silicon ladle, and when the real-time casting volume reaches a preset threshold, detecting the tilting angle of the silicon ladle; when the sum of the buffer amount corresponding to the tilting angle and the real-time casting volume reaches a preset casting standard value, the transport vehicle stops casting the molten silicon into the casting tank" specifically includes:

[0033] In the preliminary experiments, the buffer redundancy of different types of the flipping device was measured when flipping and restoring silicon packages of various sizes at different tilt angles. The average value of the buffer redundancy was calculated through multiple experiments and the average value was defined as the buffer amount.

[0034] Using the tilt angle as input and the buffer amount as output, a relationship curve between the tilt angle of the silicon package and the casting redundancy is established; the type of silicon package and the type of the flipping device are matched with the corresponding relationship curve.

[0035] Obtain the size of the silicon package carried by the transport vehicle and the type of the package-flipping device, and match them to obtain the corresponding relationship curve;

[0036] The unloaded weight of the silicon package is obtained, the overall weight of the silicon package during the silicon molten metal casting process is detected in real time, and the real-time casting amount of the silicon package to the casting tank is calculated.

[0037] When the real-time casting volume is detected to reach the preset attention value, the tilt angle of the silicon ladle is detected, the tilt angle is input into the relationship curve, and the corresponding buffer amount is calculated.

[0038] When the sum of the buffer amount and the real-time casting amount reaches the preset casting standard value, a stop casting command is sent, the ladle flipping device restores the flipping posture of the silicon ladle, and stops the silicon water casting to the casting tank;

[0039] The silicon molten metal casting is now complete.

[0040] Furthermore, this also includes multiple castings of a single silicon package, specifically including:

[0041] Obtain the total weight of the silicon package after the completion of this silicon molten metal casting, and determine whether the total weight is greater than the unloaded weight of the silicon package:

[0042] If the overall weight is not greater than the unloaded weight of the silicon package, the transport vehicle responds to the next start command;

[0043] If the overall weight is greater than the unloaded weight of the silicon package, the interval vector between the first casting trough and the second casting trough is calculated, and the ingot mold car is driven to move according to the interval vector so that the casting position of the second casting trough on the transfer track coincides with the flipping position; the silicon molten metal is poured into the second casting trough by the flipping device.

[0044] The silicon molten metal is poured into the casting tanks in the sequence multiple times until the silicon molten metal in the silicon package is completely poured or all the casting tanks in the sequence are completely poured.

[0045] Furthermore, it also includes monitoring the discharge rate of silicon water from the furnace body, specifically including:

[0046] The amount of molten silicon released each time the nozzle pours it out is obtained, and the total amount released by the furnace body is calculated.

[0047] The total weight of each casting trough on the ingot mold car is obtained in sequence. The actual amount of silicon water is calculated based on the empty weight of the casting trough. The total amount of casting of each casting rough on the ingot mold car is counted.

[0048] Calculate the difference between the total amount released and the total amount cast. If the difference exceeds the residual threshold, send an alarm report; if the difference is below the residual threshold, send a normal report.

[0049] Furthermore, it also includes monitoring the discharge rate of silicon water from the furnace body, specifically including:

[0069] To more clearly illustrate the technical solutions in the embodiments of the present invention and the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort. Furthermore, the design orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

[0070] Example 1

[0071] According to a first aspect of the present invention, a smart casting system for industrial silicon is provided, such as... Figure 1 The diagram shows a flowchart of an intelligent casting system for industrial silicon, including:

[0072] Step S101: Obtain the position information of each burner nozzle on the furnace body within the tilting area of ​​the transport vehicle's transfer track, and generate a tilting position in the tilting area based on the position information.

[0073] The implementing entity of this application can be a control system for controlling casting equipment, which includes a rotating furnace, a transport vehicle and transfer track, a ladle-turning device, and an ingot mold car. The transport vehicle has a load-bearing function and can detect the overall weight of the silicon ladle on it; the empty weight of the silicon ladle is known. The ladle-turning device is used to flip the silicon ladle to realize the casting operation. The ladle-turning device has a weighing function and can detect and calculate the real-time weight of the silicon ladle.

[0074] Please see Figure 4 The transfer track is set up around the furnace body to form a tilting area, and extends into parallel support rails. The support rails are equipped with a ladle-turning device. The ingot mold car carries multiple casting tanks parallel to the outside of the support rails. The transport car runs on the transfer track and rotates the furnace body so that the furnace nozzle is directly above the track in the tilting area. When the transport car carrying the silicon ladle is aligned with the furnace nozzle, the molten silicon can be poured. After the silicon ladle receives a certain amount of molten silicon, it runs to the ladle-turning device on the support rail. The ladle-turning device turns the silicon ladle and pours the molten silicon inside into the casting tank.

[0075] It is understandable that when controlling the transport vehicle using the method of this application, for Figure 4 The layout shown allows for symmetrical division of the casting equipment, enabling the transport vehicle to run on only one side of the transfer track, thus achieving silicon molten metal casting.

[0076] In the embodiments of this application, the furnace body can rotate autonomously, and the nozzle rotates with the furnace body. When the nozzle is in the tilting area of ​​the transfer track, it responds to the tilting command and releases silicon water. When the nozzle is not in the tilting area, it does not respond to the tilting command, and the nozzle is always in a closed state and does not release silicon water.

[0077] The furnace body rotates, changing the nozzles within the pouring area so that the nozzles on the furnace body can be used alternately. When it is necessary to pour molten silicon, the position of the nozzle must first be determined, and then the transport vehicle must be aligned with the nozzle to receive the molten silicon released from the nozzle.

[0078] In a specific embodiment, step S101 specifically includes:

[0079] Based on the position of the furnace body, a tilting area is divided on the transfer track; when the furnace nozzle of the furnace body is in the tilting area, the transport vehicle on the transfer track can receive the molten silicon tilted from the furnace nozzle;

[0080] Obtain the current rotation angle of the furnace body, and calculate the position information of each burner on the furnace body within the tilting area based on the initial position of each burner on the furnace body;

[0081] The location information is projected onto the dumping area, and the dumping position is generated based on the transfer track;

[0082] When the rotation angle of the furnace body changes, the tilting position is recalculated and generated to adapt to the rotation angle of the furnace body.

[0083] The rotation angle of the furnace body can be calculated based on the driving angle of its drive device. At the same time, the initial position of the furnace body is set. When the furnace body is in the initial position, the position of each nozzle is known. By obtaining the rotation angle of the furnace body, the current position of the nozzle can be obtained.

[0084] Since the tilting area is set around the furnace body and directly below the nozzle, the nozzle within the tilting area can be projected downwards to obtain its position information. For example, after obtaining the nozzle's position information based on the rotation angle, the tilting position of the nozzle within the tilting area can be directly determined based on the height difference between the nozzle and the transport track. When the transport vehicle reaches the tilting position, the silicon package can stably receive the molten silicon released from the nozzle.

[0085] Understandably, after each nozzle in the pouring area has poured a fixed amount of molten silicon, or after the molten silicon stored inside the furnace corresponding to the nozzle has been poured out, the furnace can rotate autonomously to change the nozzle in the pouring area. At this time, the rotation angle should be re-acquired, the nozzle position information and the production pouring position should be calculated, so that the subsequent transport vehicle can receive the molten silicon.

[0086] Step S102: When the start command is received, the carrier vehicle indicated in the start command runs to the tilting position to match. When it is detected that the carrier vehicle carrying the silicon bag has run to the corresponding tilting position, the furnace nozzle pours silicon water into the silicon bag until the silicon water pouring is completed.

[0087] In embodiments of the present invention, the starting of the transport vehicle is controlled by personnel. Specifically, the personnel can select which transport vehicle to start, and the transport vehicle carries the silicon package. When the control system receives a start command, it drives the transport vehicle indicated by the start command to run on the transfer track. It can be understood that an empty transport vehicle runs towards the tipping position to receive the molten silicon; a fully loaded transport vehicle runs towards the tipping position to pour the molten silicon.

[0088] In a specific embodiment, step S102 specifically includes:

[0089] The start command is generated by the identification code of the transport vehicle selected by the staff and the drive command;

[0090] Obtain the identification code of the transport vehicle indicated in the start command, and call the corresponding transport vehicle to the tilting position according to the identification code;

[0091] When the carrier vehicle is detected to have reached the tipping position, the empty weight of the silicon bag is obtained, and a tipping command is sent simultaneously. The furnace nozzle corresponding to the tipping position pours molten silicon into the silicon bag carried by the carrier vehicle.

[0092] The total weight of the silicon pack when receiving the silicon water is detected, and the amount of silicon water poured out is calculated;

[0093] When the amount of water poured reaches a preset quantitative value, a stop pouring command is sent.

[0094] Complete the pouring of the silica water.

[0095] In this application, each transport vehicle has a unique identification code, and staff select the transport vehicle based on the identification code. The start command includes at least the identification code selected by the staff and a preset drive command. When the control system receives the start command, it first extracts the identification code to determine the target of the command, and then obtains the drive command to determine the execution attribute of the command.

[0096] It is understandable that when generating the startup command, the selected identification code can be added first, and then the preset driver command can be called to add it, thereby generating the startup command.

[0097] In the embodiments of this application, the transport vehicle runs along the transfer track toward the tilting position. As one feasible embodiment, a sensor for detecting the position of the transport vehicle can be set on the track within the tilting area to accurately detect the position information of the transport vehicle. As another feasible embodiment, a travel detector can be set on the transport vehicle to detect the travel of the transport vehicle on the transfer track to accurately detect the position information of the transport vehicle.

[0098] Understandably, the silicon packs are mounted on a weighing device on the transport vehicle, allowing the vehicle to monitor the overall weight of the silicon packs in real time. The empty weight of the silicon packs is known data, and there may be some difference between the "empty weight" of the silicon packs detected by the transport vehicle and the known data due to the influence of residual silica water; when calculating the amount of silica water poured out, the known data shall prevail.

[0099] In the embodiments of this application, the amount of molten silica poured can be determined by subtracting the known empty weight from the total weight obtained from the detection. When the amount poured reaches a preset quantitative value, a stop pouring command can be sent, and the pouring spout can be directly closed. The transport vehicle should wait for a period of time until the residual molten silica in the pouring spout has drained before proceeding to the casting position. It is understood that the waiting time of the transport vehicle can be preset according to the size and inclination of the pouring spout, and a suitable waiting time can also be determined experimentally.

[0100] It is understandable that after sending the stop pouring command, the pouring of molten silica is considered complete, and the casting target can be determined for the transport vehicle. The determination of the casting target can be completed within the waiting time. When the transport vehicle moves towards the location of the casting target, the molten silica in the pouring outlet has completely drained. In the embodiments of this application, the casting target is a casting tank, and multiple casting tanks are arranged in sequence and pulled by an ingot mold vehicle.

[0101] Step S103: Locate the casting slot that is idle and first in the order on the ingot mold car and align it with the casting position on the transfer track. Adjust the ingot mold car until the casting position coincides with the flipping position on the transfer track.

[0102] In an embodiment of the present invention, the ingot mold car is equipped with a single row of casting tanks, and its running direction is parallel to the support rail of the transfer track. The support rail is provided with a ladle flipping device, which corresponds to the ladle flipping position. When the transport car reaches the ladle flipping position, the ladle flipping device can flip the silicon ladle on the transport car that is in the ladle flipping position, thereby pouring the molten silicon in the silicon ladle into the casting tank.

[0103] It is understandable that during casting, the casting trough to be cast and the ladle turning position need to correspond in order to accurately cast the molten silicon into the casting trough. In this application, the correspondence between the casting trough and the ladle turning position is adjusted by driving the ingot mold car.

[0104] In a specific embodiment, step S103 specifically includes:

[0105] Obtain the status information of each casting trough mounted on the ingot mold car; the casting trough is in an idle state if and only if the weight of the casting trough is within a threshold range;

[0106] Extract the casting troughs that are in an idle state and sort them according to the mounting order of the casting troughs on the ingot mold car;

[0107] Obtain the relative positional relationship between the ingot mold car and the transfer track, and calculate the casting position on the transfer track corresponding to the first casting trough;

[0108] Calculate the difference vector between the casting position and the ladle turning position, and drive the ingot mold car to move according to the difference vector so that the casting position corresponding to the first casting trough on the transfer track coincides with the ladle turning position.

[0109] In this application, the idle casting slots on the ingot mold car are sorted, and casting is performed only on the first idle casting slot at a time. After the first casting slot is completed, the sorting can be refreshed to change the first casting slot.

[0110] The idle state of a casting tank can be determined based on its weight. A predefined threshold range for a casting tank to be in an unloaded state is used. When the weight of the casting tank is detected to be within the threshold range, it is determined that the casting tank is in an idle state. It can be understood that the lower limit of the threshold range can be the unloaded weight of the casting tank, and the upper limit can be the fully loaded weight of the casting tank. When the molten silicon in the silicon ladle is insufficient, a secondary casting can be performed on the unloaded casting tank using subsequent silicon ladles.

[0111] In this application, the casting position of the casting trough on the support rail can be calculated based on the distance between the casting trough and the support rail. The ingot mold car is driven so that the casting position coincides with the ladle flipping position. The silicon ladle can then be flipped by the ladle flipping device to achieve the casting of silicon water into the casting trough.

[0112] When driving the ingot mold car, the difference vector can be calculated based on the position information of the casting position and the ladle flipping position. The position of the ingot mold car is adjusted according to the direction and distance of the difference vector, so that the casting trough and the ladle flipping device are aligned. At this time, the casting position and the ladle flipping position coincide.

[0113] The transport vehicle moves towards the casting position. Once the casting position coincides with the ladle-turning position, the transport vehicle can directly move to the ladle-turning position to carry out the ladle-turning operation.

[0114] Step S104: The transport vehicle carrying the silicon molten material is matched to the casting position. When the transport vehicle carrying the silicon bag reaches the flipping position, the silicon bag is flipped and the silicon molten material is poured into the casting tank.

[0115] In an embodiment of the present invention, the casting target of the transport vehicle that completes the pouring of molten silica is the first available casting tank. After the casting target is determined, the transport vehicle moves to the casting position, and the flipping device performs the flipping operation to pour molten silica into the casting tank.

[0116] In one specific embodiment, step S104 specifically includes:

[0117] The casting position is found to coincide with the overturning position. The casting position is obtained, and the transport vehicle that has completed the pouring of molten silica is driven to run towards the casting position.

[0118] When the transport vehicle carrying silicon packages is detected to have reached the package-flipping position, a package-flipping command is sent to activate the package-flipping device to perform the package-flipping operation on the silicon packages.

[0119] The flipping device flips the silicon package and pours the molten silicon into the casting tank.

[0120] In the embodiments of this application, regarding the movement of the transport vehicle that has completed the pouring (full load) of molten silica towards the casting position:

[0121] For safety and stability reasons, it is advisable to first check whether the casting position and the ladle turning position coincide. Once they do, the fully loaded transport vehicle can be driven to the casting position.

[0122] For operational efficiency, the fully loaded transport vehicle can be driven directly to the casting position, and the ingot mold car can be driven synchronously to make the casting position coincide with the ladle turning position. Since the travel distance of the transport vehicle is relatively far from the adjustment distance of the ingot mold car, there is enough time for the casting position and the ladle turning position to coincide before the transport vehicle reaches the casting position.

[0123] In this application, a sensor can be set at the ladle-turning position to detect whether the transport vehicle has arrived. When the transport vehicle is detected to have arrived at the ladle-turning position (at which time the casting position coincides with the ladle-turning position), a ladle-turning command is sent to start the ladle-turning device to perform the ladle-turning operation on the silicon ladle carried on the transport vehicle, so that the silicon water in the silicon ladle flows into the casting tank and the casting tank is cast.

[0124] For example, the packing-flipping device includes a fixed fulcrum and an opening / closing fulcrum. The opening / closing fulcrum is located on the outer side of the support rail (the side closest to the mold car), and the fixed fulcrum is located on the inner side of the support rail. Normally, the packing-flipping device flips upwards via the fixed fulcrum, opening the operating space of the support rail so that the transport vehicle can move to the packing-flipping position. When the arrival of the transport vehicle is detected, the packing-flipping device flips downwards via the fixed fulcrum, the opening / closing fulcrum closes, and the silicon package is locked and flipped outwards. It is understood that the flipping power of the packing-flipping device can be achieved through a telescopic cylinder.

[0125] Step S105: Detect the real-time casting volume of the silicon ladle. When the real-time casting volume reaches the preset target value, detect the tilting angle of the silicon ladle. When the sum of the buffer amount corresponding to the tilting angle and the real-time casting volume reaches the preset casting standard value, the transport vehicle stops casting the silicon water into the casting tank.

[0126] In embodiments of the present invention, the flipping device flips the silicon package to allow the silicon water inside to flow out. However, when the silicon package is flipped back to its original state, the silicon water does not immediately stop flowing as the valve body control structure does, and it also has a certain buffer redundancy.

[0127] Therefore, through experiments, the buffer redundancy of different types of ladle-turning devices during ladle recovery under different tilt angles can be determined for ladle of different sizes. The average value of the buffer redundancy can be obtained by repeating the experiment multiple times. When calculating the casting volume, this average value can be called based on the tilt angle of the ladle and added to the casting volume to obtain the true casting volume.

[0128] Furthermore, based on experimental data, a recommended value for the tilt angle of the turning device when turning the silicon package can be obtained. The tilt angle with small buffer redundancy fluctuations can be selected as the recommended value to quantitatively control the silicon molten metal casting.

[0129] In one specific embodiment, step S105 specifically includes:

[0130] In the preliminary experiments, the buffer redundancy of different types of the flipping device was measured when flipping and restoring silicon packages of various sizes at different tilt angles. The average value of the buffer redundancy was calculated through multiple experiments and the average value was defined as the buffer amount.

[0131] Using the tilt angle as input and the buffer amount as output, a relationship curve between the tilt angle of the silicon package and the casting redundancy is established; the type of silicon package and the type of the flipping device are matched with the corresponding relationship curve.

[0132] Obtain the size of the silicon package carried by the transport vehicle and the type of the package-flipping device, and match them to obtain the corresponding relationship curve;

[0133] The unloaded weight of the silicon package is obtained, the overall weight of the silicon package during the silicon molten metal casting process is detected in real time, and the real-time casting amount of the silicon package to the casting tank is calculated.

[0134] When the real-time casting volume is detected to reach the preset attention value, the tilt angle of the silicon ladle is detected, the tilt angle is input into the relationship curve, and the corresponding buffer amount is calculated.

[0135] When the sum of the buffer amount and the real-time casting amount reaches the preset casting standard value, a stop casting command is sent, the ladle flipping device restores the flipping posture of the silicon ladle, and stops the silicon water casting to the casting tank;

[0136] The silicon molten metal casting is now complete.

[0137] In this application, the tilt angle is used as a variable, and the buffer amount is calculated through a relationship curve. The buffer amount is added to the real-time casting amount to obtain the actual casting amount. By comparing the actual casting amount with the standard casting value, the true casting situation can be obtained, which is beneficial to the standardization of casting. It is understood that the standard casting value is related to the capacity of the casting tank.

[0138] When the actual casting volume is detected to have reached the casting standard value, a stop casting command can be sent, the ladle flipping device will restore the silicon ladle to its flipping position, and stop the casting of silicon water into the casting tank.

[0139] It is understandable that a guide channel is provided between the silicon ladle and the casting tank to guide the flow of molten silicon. The position of the guide channel can be fixed based on the ladle flipping position. The guide channel is located between the silicon ladle and the casting tank, with the upper end receiving the molten silicon and the lower end connecting to the casting tank, so that the molten silicon can flow steadily into the casting tank during silicon ladle casting.

[0140] In the embodiments of this application, the flipping device can drive the flipping of the silicon package by a hydraulic telescopic device. When the flipping device flips the silicon package, the gravity fulcrum mainly falls on the opening and closing fulcrum. A weighing sensor can be set at the opening and closing fulcrum. When flipping, the extension and retraction stroke of the hydraulic telescopic device is adjusted by the detection value of the weighing sensor.

[0141] For example, the extension stroke of the hydraulic telescopic device is adjusted based on the rate of change of the detected values:

[0142] When the actual rate of change decreases, it indicates that the rate of pouring the silicon water has slowed down. The rate of change of the telescopic stroke can be increased, and the tilt angle of the silicon package can be increased.

[0143] When the actual rate of change increases, it indicates that the tilt angle of the silicon package is increasing too fast. The rate of change of the telescopic stroke can be reduced, and the tilt angle of the silicon package can be decreased.

[0144] When the actual rate of change is zero and the detected value reaches the no-load range of the silicon package, the silicon package automatically resumes its flipping state; the telescopic stroke is reduced to the minimum value.

[0145] When a stop casting command is received, the silicon ladle automatically resumes its flipping state; the extension stroke is reduced to the minimum value.

[0146] It is understandable that the measured value cannot directly represent the actual weight of the silicon package. The measured value can be converted into the actual weight, and then the rate of change of the parameter can be calculated, i.e., the actual rate of change.

[0147] Based on the above method steps, when the capacity inside the silicon package is much larger than the capacity of the casting tank, a single silicon package can be used for multiple castings, specifically including:

[0148] Obtain the total weight of the silicon package after the completion of this silicon molten metal casting, and determine whether the total weight is greater than the unloaded weight of the silicon package:

[0149] If the overall weight is not greater than the unloaded weight of the silicon package, the transport vehicle responds to the next start command;

[0150] If the overall weight is greater than the unloaded weight of the silicon package, the interval vector between the first casting trough and the second casting trough is calculated, and the ingot mold car is driven to move according to the interval vector so that the casting position of the second casting trough on the transfer track coincides with the flipping position; the silicon molten metal is poured into the second casting trough by the flipping device.

[0151] The silicon molten metal is poured into the casting tanks in the sequence multiple times until the silicon molten metal in the silicon package is completely poured or all the casting tanks in the sequence are completely poured.

[0152] In the embodiments of this application, for a large amount of silicon ladle, after being fully loaded with molten silicon, multiple casting tanks may be needed to completely consume the molten silicon inside. Based on the order of the available casting tanks, the casting tanks in the second, third, ..., Nth positions can be cast in sequence. During this process, the position of the ingot mold car can be adjusted to align the casting position of each slot with the ladle flipping position, thus satisfying the prerequisite for molten silicon casting.

[0153] Based on the method of this application, during the silicon molten metal casting process, the production volume and actual casting volume of silicon molten metal can be monitored in real time, allowing for comparison and monitoring of silicon molten metal discharge, thus controlling the rationality of the production process. The monitoring of silicon molten metal discharge in the furnace body specifically includes:

[0154] The amount of molten silicon released each time the nozzle pours it out is obtained, and the total amount released by the furnace body is calculated.

[0155] The total weight of each casting trough on the ingot mold car is obtained in sequence. The actual amount of silicon water is calculated based on the empty weight of the casting trough. The total amount of casting of each casting rough on the ingot mold car is counted.

[0156] Calculate the difference between the total amount released and the total amount cast. If the difference exceeds the residual threshold, send an alarm report; if the difference is below the residual threshold, send a normal report.

[0157] In the embodiments of this application, the silicon molten metal output of each furnace nozzle can be statistically analyzed in real time and compared with the casting volume. This ensures the normal use of silicon molten metal in the production process. When the casting gap of silicon molten metal is too large, an alarm report is issued, which can be inspected and corrected by management personnel. It is understood that comparison based on daily output is beneficial for formulating a rigorous production plan.

[0158] Based on the method of this application, the travel data of the transport vehicle can be monitored during its operation, and the operating status of the transport vehicle can be reported in a timely manner. When the travel data of the transport vehicle is interrupted, it indicates that the transport vehicle has malfunctioned. At this time, regardless of whether the transport vehicle is empty or fully loaded, it cannot move to the overloading position or maintenance position on its own, and a towing alarm can be sent in a timely manner, so that the personnel can carry out external towing.

[0159] Understandably, in the casting environment, the available power source is a crane, but the crane is too high to directly traction the transport vehicle. As a feasible implementation, a steering pulley can be installed at the end of the support rail. One end of the traction rope is connected to the crane, and the other end passes through the steering pulley and is connected to the transport vehicle. In this case, the tension of the traction rope is almost at the same level as the base of the transport vehicle.

[0160] Understandably, since the fault location of the transport vehicle can be either a curved rail (overturning area) or a straight rail (support rail), the traction rope, after being turned and parallel to the straight rail, can directly pull the transport vehicle located on the straight rail, but cannot directly pull the transport vehicle on the curved rail. As a feasible embodiment, horizontal rollers can be installed on the outer wall of the curved rail to guide the traction rope to turn horizontally. A fixed bracket is installed on the lower side of the horizontal roller, and an opening is provided on the upper side to facilitate the insertion of the traction rope. Understandably, the traction rope can be steel wire, chain, etc.

[0161] When traction is performed, for transport vehicles on straight rails, traction can be performed directly without the need for horizontal rollers for steering guidance. For transport vehicles on curved rails, the traction rope can be passed through multiple horizontal rollers in sequence for steering guidance. As the transport vehicle's running position changes, the traction rope is removed from the horizontal rollers one by one until the transport vehicle runs on straight rails. At this point, the traction rope is released from all horizontal rollers.
