Description

Technical Field

[0001] The present invention relates to the technical field of the iron and steel industry, and particularly to an efficient method for transporting and pouring molten metal. Background Art

[0002] In the technical field of the iron and steel industry, casting and molding is a main production (molding) method, which refers to the production process of melting metal into molten metal and pouring it into a specific mold for cooling and molding.

[0003] The applicant has previously applied for a variety of pouring and transfer systems for molten metal. For example, the application document with the application number CN202020488068.X discloses an intelligent hot metal transfer system, which efficiently transports hot metal to the pouring machine through the cooperation of a front-of-furnace transfer vehicle, a rotary transfer vehicle and a tilting transfer vehicle. Such a hot metal transfer system, including other transfer and pouring systems applied by the applicant, can effectively reduce the heat loss of hot metal during the transfer process and efficiently complete the transfer and pouring work of hot metal, providing structural support for the efficient transfer and pouring of molten metal.

[0004] However, in terms of the pouring method of the system, there are still some deficiencies. For example, the system can only be applied to the pouring of a single mold. When the mold changes, it is necessary to make multiple adjustments or even re-enter the operation instructions to make the system continue to run. Especially when there are multiple molds on the molding line, the pouring production operation becomes more troublesome, and it is still impossible to efficiently complete the transfer and pouring work of molten metal. At the same time, the pouring positions and pouring amounts of different molds are different, which makes the transfer and pouring work more troublesome. Summary of the Invention

[0005] To solve the technical problems existing in the above background art, the present invention provides an efficient method for transporting and pouring molten metal.

[0006] The technical solution of the present invention is as follows:

[0007] An efficient method for transporting and pouring molten metal, which includes the following steps:

[0008] S1. Start the system through the start switch of the total control module. The start switch can be a toggle switch or a push-button switch;

[0009] S2. Confirmation of the pouring mold:

[0010] S2.1. The first image processing module on the molding line receives the image information of several consecutive molds in the first area, and sequentially generates the pouring position information and pouring quality information of each mold according to the image information;

[0011] S2.2. The second image processing module on the molding line receives the image information of several consecutive molds in the second area, and generates the preliminary position information and preliminary quality information of each mold according to the order of the image information;

[0012] S2.3. The image processing module transfers the pouring position information, pouring quality information, preliminary position information, and preliminary quality information to the total control module;

[0013] S3. Transfer and pouring:

[0014] S3.1. The total control module controls the movement of the transfer vehicle in front of the furnace, and the transfer vehicle carries the transfer ladle to dock with the electric furnace to pick up the molten metal with a mass of G 总 while G always satisfies:

[0015] G max > G 总 ≥ G 单 and G 总 ≤ G' max ;

[0016] where G 单 is the sum of several pouring quality information, G max is the mass of the molten metal when the transfer ladle is full, and G' max is the mass of the molten metal when the pouring ladle is full;

[0017] S3.2. The total control module controls the transfer vehicle in front of the furnace to dock with the pouring machine, and pours the molten metal into the pouring ladle located on the pouring machine;

[0018] S3.3. The total control module controls the pouring machine to move to the starting pouring position, and then completes the pouring work of several molds in the first area one by one according to the pouring position information and pouring quality information;

[0019] S4. Mold feeding:

[0020] S4.1. The total control module controls the movement of the molding line, several molds in the first area are transported forward, and several molds in the second area are moved as a whole to the first area. At this time, the preliminary position information and preliminary quality information are automatically updated and converted into new pouring position information and pouring quality information;

[0021] S4.2. If there are new molds entering the second area, the second image processing module receives the image information of several consecutive molds in the second area, generates new preliminary position information and preliminary quality information, transfers the new preliminary position information and preliminary quality information to the total control module, and continues to execute step S5;

[0022] If the second image processing module does not detect new preliminary position information and / or the new preliminary quality information is zero, the system continues to run after step S3.3 and then stops running;

[0023] S5, Delay control:

[0024] The delay control unit of the master control module controls the continued operation of step S3 according to the pouring completion time of several molds in step S3.3 and the zone change time required for the overall movement of several molds to the first zone in step S4.1.

[0025] In this method, the design of the image processing module enables it to generate pouring position information and pouring quality information based on the mold information on the molding line, and then controls the pouring machine to complete the pouring work of the mold. Even if the molds on the molding line are different, the system can still complete the pouring operation without having to re-enter control instructions or make other unnecessary adjustments, ensuring the efficient progress of the transfer and pouring work; moreover, the design of the dual zones enables the preparation position information and preparation quality information of the molds in the second zone to be determined while the molds in the first zone are being poured. After the pouring of the molds in the first zone is completed and the molds in the second zone reach the first zone as a whole, the system can immediately continue pouring according to the preparation position information and preparation quality information, without waiting time for mold confirmation, further ensuring the efficient progress of the pouring work; at the same time, the design method of step S5 enables the time for the ladle transfer car in front of the furnace to receive the molten metal to match the start time of continued pouring, avoiding heat dissipation of the molten metal during the waiting process due to the ladle transfer car in front of the furnace receiving the molten iron in advance, ensuring the pouring quality, and efficiently completing the transfer and pouring work of the molten metal through the cooperation of the ladle transfer car in front of the furnace and the pouring machine.

[0026] In a highly efficient method for transferring and pouring molten metal as described above, as a preferred implementation, in step S2, if the first image processing module and / or the second image processing module cannot obtain complete image information of the mold, the master control module controls the molding line to move to a position where both the first image processing module and the second image processing module can obtain complete image information of the mold. If complete image information cannot be obtained by controlling the movement of the molding line, the system stops running, and the position of the mold is manually adjusted to ensure that the image processing module can obtain accurate pouring / preparation quality information and pouring / preparation position information of the mold.

[0027] As a further preference, the area and specifications of the first zone and the second zone are the same, enabling the molds in the second zone to be translated as a whole to the first zone, and after being translated to the first zone, the preparation position information and preparation quality information can be directly converted into pouring position information and pouring quality information for use without other calculations, enabling the transfer and pouring work to proceed quickly.

[0028] Furthermore, the processing methods of the first image processing module and the second image processing module are the same. The specific steps include:

[0029] A. Obtain a high-definition image through an acquisition camera;

[0030] B. The image processing module pre-stores one-to-one corresponding shape information and quality information internally. Pick up the edge feature points of the mold in the high-definition image to obtain the shape information of the mold, and retrieve the corresponding quality information according to the shape information of the mold;

[0031] C. Based on the gate position feature points of the mold in the high-definition image, obtain the position information of the mold gate.

[0032] For an efficient metal melt transfer and pouring method as described above, in step S3, 1.1G 单 ≤G 总 ≤1.25G 单 , on the premise of avoiding excessive waste of the metal melt, ensure that there is sufficient metal melt in the pouring ladle, and avoid wasting transfer and pouring time due to the need to replenish the metal melt when it is insufficient.

[0033] Further, in step S3.2, the front-of-furnace transfer vehicle includes a first roller track docked with the electric furnace and a second roller track docked with the pouring machine. A weighing mechanism is provided under the first roller track, and the weighing mechanism is communicatively connected to the total control module for real-time feedback of the mass of the metal melt received in the transfer ladle. A lifting and tilting mechanism is provided on one side of the second roller track. The transfer ladle containing the metal solution can be translated from the first roller track to the second roller track and lifted by the lifting and tilting mechanism on one side of the second roller track, and the action of pouring the metal melt into the pouring ladle is completed.

[0034] For an efficient metal melt transfer and pouring method as described above, in step S3.3, the starting pouring position of the pouring machine is at one end of the first area close to the front-of-furnace transfer vehicle, so that after the pouring machine is docked with the front-of-furnace transfer vehicle, it can quickly reach the starting pouring position and start the pouring work, further ensuring the efficient progress of the pouring work.

[0035] For an efficient metal melt transfer and pouring method as described above, in step S5, the end time when several molds in the second area are moved as a whole to the first area is the same as the end time of step S3.1, avoiding the waiting time of the front-of-furnace transfer vehicle, resulting in excessive heat dissipation of the metal melt and ensuring the pouring quality.

[0036] Specifically for the step S5, several pouring completion time information t1 and corresponding response information are pre-stored in the master control module. The response information includes pouring times information n and first quality information m1. The master control module can automatically retrieve the corresponding t1 according to n and m1. The area change time is t2, and t2 = d / s, where d is the distance moved when several molds in the second area are moved to the first area as a whole, s is the working speed of the molding line, and both d and s are set in the master control module. Several molten iron receiving time information t3 and the uniquely corresponding second quality information m2 are also pre-stored in the master control module. The master control module can automatically retrieve the corresponding t3 according to m2. The delay control unit starts timing from when the pouring machine starts pouring. After a delay of t4 time period, it controls to execute step S3, and t4 = t1 + t2 - t3.

[0037] For an efficient metal melt transfer and pouring method as described above, the master control module further includes an emergency stop switch, so that after the transfer and pouring process gets out of control or other accidents occur, the control system can be stopped through the emergency stop switch to prevent the accident from further expanding.

[0038] The beneficial effects of the present invention are as follows: The present invention is an efficient metal melt transfer and pouring method, including steps of starting, mold confirmation, transfer and pouring, and mold feeding. The system can generate pouring position information and pouring quality information based on the mold information on the molding line, and then control the pouring machine to complete the pouring work of the mold. Even if the molds on the molding line are different, the system can still complete the pouring operation without having to re-enter control instructions or make other unnecessary adjustments, ensuring the efficient progress of the transfer and pouring work. Moreover, the design of the double area enables the preparation position information and preparation quality information of the molds in the second area to be determined while the molds in the first area are being poured. After the molds in the first area are poured and the molds in the second area reach the first area as a whole, the system can immediately continue pouring according to the preparation position information and preparation quality information without waiting time for mold confirmation, further ensuring the efficient progress of the pouring work. At the same time, the time for the front-of-furnace transfer cart to receive the metal solution can be matched with the start time of continuous pouring, avoiding heat dissipation of the metal melt during the waiting process due to the front-of-furnace transfer cart receiving the molten iron in advance, ensuring the pouring quality, and efficiently completing the transfer and pouring work of the metal melt through the cooperation of the front-of-furnace transfer cart and the pouring machine.

[0048] Embodiment

[0049] This embodiment first provides a transfer and pouring system. Combining Figure 1 , the transfer and pouring system includes a transfer module 1 and a storage roller path 2 located on one side thereof. An electric furnace 3 is also provided on one side of the transfer module 1, and a pouring module 4 is provided on the opposite side. One side of the pouring module 4 is a molding line 5. The molding line 5 includes a transportation part and molds arranged thereon that can move along with it. The transfer module 1 can dock with the storage roller path 2 to pick up an empty pouring ladle 8, transfer the molten metal in the electric furnace 3 to the pouring module 4, and the pouring module 4 completes the pouring work on the molds on the transportation part.

[0050] Regarding the structure of the transfer module 1, combining Figure 2 , it includes a transfer track 11 and a transfer vehicle 12 in front of the furnace arranged thereon. The storage roller path 2 is located on one side of the transfer track 11, and a transfer ladle 7 is stored thereon. The transfer vehicle 12 in front of the furnace includes a second roller path 122 that can dock with the storage roller path 2. The transfer vehicle 12 in front of the furnace can move to the docking position with the storage roller path 2, and the transfer ladle 7 can be transferred from the storage roller path 2 to the second roller path 122.

[0051] Further, the circuit is located on the side of the transfer track 11 away from the storage roller track 2. A first roller track 121 capable of docking with the electric furnace 3 is provided on the side of the second roller track 122 close to the electric furnace 3. The transfer package 7 can be transported between the first roller track 121 and the second roller track 122. A weighing mechanism is further provided under the first roller track 121. When the transfer package 7 is located on the first roller track 121, it can dock with the electric furnace 3 to receive the molten metal, and the mass of the received molten metal can be monitored in real time by the weighing mechanism.

[0052] Specifically regarding the structure of the pouring module 4, in combination with Figure 3 , it includes a pouring track 41 and a pouring machine 42 arranged thereon. The arrangement direction of the pouring track 41 is perpendicular to the transfer track 11. The pouring machine 42 includes a third roller track 421. A pouring package 8 capable of moving along it is placed on the third roller track 421. A lifting and tilting mechanism 123 is further provided on one side of the second roller track 122. The pouring package 8 can move along the third roller track 421 to be close to the side of the furnace front transfer vehicle 12. The transfer package 7 on the second roller track 122 can be lifted under the action of the lifting and tilting mechanism 123, and the molten metal is poured into the pouring package 8 to complete the docking work between the second roller track 122 and the pouring machine 42.

[0053] Further, the molding line 5 is located on one side of the pouring track 41. A lifting and pouring mechanism 422 is provided on the side of the third roller track 421 away from the furnace front transfer vehicle 12. The pouring package 8 can move along the third roller track 421 to cooperate with the lifting and pouring mechanism 422, and can be lifted under the action of the lifting and pouring mechanism 422 to complete the pouring work of the mold.

[0054] This embodiment also provides an efficient method for transporting and pouring molten metal, including the following steps:

[0055] S1. Start the control system to run through the start switch of the total control module. The start switch can be a toggle switch or a push button switch;

[0056] S2. Confirm the pouring mold;

[0057] S2.1. The first image processing module on the molding line 5 receives the image information of several consecutive molds in the first area, and generates the pouring position information and pouring quality information of each mold according to the image information sequence. Specifically:

[0058] A. The first area obtains high-definition images of the molds in the area through the first acquisition camera of the first image processing module. In this embodiment, taking the collected image information as Figure 4 as an example, Figure 4 the left dotted box in it is the first area. There are a first mold 51, a second mold 52, and a third mold 53 in the first area from left to right in sequence;

[0059] B. The first image processing module includes a processing unit, which pre-stores corresponding shape information and quality information. The processing unit picks up the edge feature points of the three molds in the high-definition image to obtain the shape information of the molds, and retrieves the corresponding quality information according to the shape information of the molds (hexagon, circle, and triangle), which is the pouring quality information of the molds.

[0060] C. The processing unit automatically picks up the gate position feature points (feature round holes circumferentially arranged outside the gate) of the three molds in the high-definition image, and obtains the position information of the mold gates (the center of the figure surrounded by the feature round holes) according to the gate position feature points, which is the pouring position information of the molds.

[0061] S2.2. The second image processing module on the molding line 5 receives the image information of several consecutive molds in the second area, and sequentially generates the preliminary position information and preliminary quality information of each mold. Specifically:

[0062] A. The second area obtains the high-definition image of the molds in the area through the second acquisition camera of the second image processing module. In this embodiment, the collected image information is as Figure 4 For example, Figure 4 The right dotted box in the figure is the second area. There are a third mold 53, a first mold 51, and a second mold 52 in the second area from left to right in sequence.

[0063] B. The second image processing module also includes a processing unit. The processing unit automatically picks up the edge feature points of the three molds in the high-definition image to obtain the shape information of the molds, and retrieves the corresponding quality information according to the shape information of the molds (triangle, hexagon, and circle), which is the preliminary quality information of the molds.

[0064] C. The processing unit automatically picks up the gate position feature points (feature round holes circumferentially arranged outside the gate) of the three molds in the high-definition image, and obtains the position information of the mold gates (the center of the figure surrounded by the feature round holes) according to the gate position feature points, which is the preliminary position information of the molds.

[0065] S2.3. The image processing module transmits the pouring position information, pouring quality information, preliminary position information, and preliminary quality information to the total control module.

[0066] It should be noted that in step S2, if the first image processing module and / or the second image processing module cannot obtain complete image information of the mold. For example, when the mold is located on the boundary line between two regions, at this time, since the processing unit cannot pick up effective edge feature points, it is impossible to obtain effective mold shape information, or the mold shape information obtained after picking up the edge feature points does not exist in the processing unit. Then, the total control module controls the transport part of the molding line 5 to move to a position where both the first image processing module and the second image processing module can obtain complete image information of the mold. If it is impossible to obtain complete image information by controlling the movement of the transport part, the system stops running. After manually adjusting the position of the mold to ensure that the image processing module can obtain accurate pouring / preparation quality information and pouring / preparation position information of the mold, the operation is resumed manually;

[0067] S3. Transfer and pour;

[0068] S3.1. The total control module controls the front-furnace transfer vehicle 12 to move. First, it docks with the storage roller table 2 to pick up an empty transfer ladle 7, and then carries the transfer ladle 7 to dock with the electric furnace 3 to pick up molten metal of G 总 quality. The weighing mechanism is communicatively connected to the total control module and is used to real-time feedback the mass of the molten metal contained in the transfer ladle 7. At the same time, G 总 should at least satisfy:

[0069] G max >G 总 ≥G 单 , and G 总 ≤G’ max ;

[0070] Where G 单 is the sum of several pouring quality information, G max is the mass of the molten metal when the transfer ladle 7 is full, G’ max is the mass of the molten metal when the pouring ladle 8 is full. Preferably, 1.1G 单 ≤G 总 ≤1.25G 单 . On the premise of avoiding excessive waste of molten metal, ensure that there is sufficient molten metal in the pouring ladle 8 to avoid wasting transfer and pouring time due to insufficient molten metal and the need for liquid supplementation;

[0071] S3.2. The total control module controls the front-furnace transfer vehicle 12 to dock with the pouring machine 42 and pour the molten metal into the pouring ladle 8 located on the pouring machine 42;

[0072] S3.3. The master control module controls the pouring machine 42 to move to the starting pouring position, and then, according to the pouring position information and the pouring quality information, completes the pouring work for several molds in the first area one by one. It should be noted that the transportation direction of the molds in the first area and the second area points to the side of the transfer module 1. The starting pouring position of the pouring machine 42 is at one end of the first area close to the front-of-furnace transfer cart 12, so that after the pouring machine 42 is docked with the front-of-furnace transfer cart 12, it can quickly reach the starting pouring position and start the pouring work, further ensuring the efficient progress of the pouring work;

[0073] S3.4. There is also a waste liquid bucket 6 on one side of the pouring track. After step S3.3 is completed, the pouring machine 42 carries the pouring ladle 8 and moves to the position of the waste liquid bucket 6 to complete a waste liquid pouring action;

[0074] S4. Mold feeding;

[0075] S4.1. The master control module controls the transportation part of the molding line 5 to move, driving three molds in the first area to be transported forward, and the three molds in the second area move as a whole to the first area. At the same time, new molds enter the second area. At this time, the preparatory position information and preparatory quality information of the three molds are automatically converted into new pouring position information and pouring quality information. Preferably, the area and specifications of the first area and the second area are the same, so that the molds in the second area can be translated as a whole to the first area, and after being translated to the first area, the preparatory position information and preparatory quality information can be directly converted (equivalently replaced) into pouring position information and pouring quality information for use without other calculations, enabling the transfer and pouring work to be carried out quickly;

[0076] S4.2. The second image processing module receives the image information of several consecutive molds in the second area, generates new preparatory position information and preparatory quality information, and transmits the new preparatory position information and preparatory quality information to the master control module. If the second image processing module does not detect new preparatory position information and / or the new preparatory quality information is zero, the system continues to run step S3.3 and then stops running;

[0077] S5. Delay control;

[0078] The delay control unit of the master control module controls the continued execution time of step S3 according to the pouring completion time of several molds in step S3.3 and the zone change time required for several molds to move as a whole to the first area in step S4.1. Preferably, the end time when several molds in the second area move as a whole to the first area is the same as the end time of step S3.1, avoiding the waiting time of the front-of-furnace transfer cart 12 and resulting in excessive heat dissipation of the molten metal, and ensuring the pouring quality. The specific delay control method is as follows:

[0079] The general control module prestores a number of time information t1 required for pouring completion, and corresponding response information. The response information includes pouring times information n and first quality information m1. Here, n is the number of molds in the first area in step S3.3, and m1 is the mass of the molten metal required for pouring a number of molds in the first area in step S3.3. The general control module can automatically retrieve the corresponding t1 according to n and m1;

[0080] The time required for area change is t2, and t2 = d / s, where d is the distance moved when a number of molds in the second area move to the first area in step S4.1, s is the working speed of the molding line, and both d and s are preset manually in the general control module;

[0081] The general control module also prestores a number of time information t3 required for receiving molten iron, and corresponding second quality information m2. And m2 is the mass of the molten metal required for pouring a number of molds in the second area in step S3.3 (before step S4.1). The general control module can automatically retrieve the corresponding t3 according to m2;

[0082] The delay control unit starts timing from when the pouring machine starts pouring in step S3.3. After a delay of t4 time period, it controls to execute step S3, and t4 = t1 + t2 - t3.

[0083] In this method, the design of the image processing module enables it to generate pouring position information and pouring quality information based on the mold information on the molding line 5, and then control the pouring machine 42 to complete the pouring work of the molds. Even if the molds on the molding line 5 are different, the system can still complete the pouring operation without re-entering control instructions or making other unnecessary adjustments, ensuring the efficient progress of the transfer and pouring work; moreover, the design of the double area enables the preparatory position information and preparatory quality information of the molds in the second area to be determined when the molds in the first area are being poured. After the molds in the first area are poured and the molds in the second area reach the first area as a whole, the system can immediately continue pouring according to the preparatory position information and preparatory quality information, without waiting time for mold confirmation, further ensuring the efficient progress of the pouring work; at the same time, the design method of step S5 enables the time for the front-of-furnace transfer vehicle 12 to receive the molten metal to match the start time of continuous pouring, avoiding heat dissipation of the molten metal during the waiting process due to the front-of-furnace transfer vehicle 12 receiving the molten iron in advance, ensuring the pouring quality, and efficiently completing the transfer and pouring work of the molten metal through the cooperation of the front-of-furnace transfer vehicle 12 and the pouring machine 42. To ensure the safe operation of the system, the general control module also includes an emergency stop switch, so that the transfer and pouring process can be stopped by the emergency stop switch when it gets out of control or other accidents occur, avoiding the further expansion of the accident.
