Description

Technical Field

[0001] This application relates to the field of metallurgical technology, and particularly relates to a trial tilting method for a torpedo ladle and related equipment. Background Art

[0002] The torpedo ladle is the core equipment for molten iron transportation in iron and steel enterprises. Its pouring operation requires tilting the torpedo ladle to pour the molten iron into the ladle. In traditional operations, the tilting direction of the torpedo ladle is judged manually: the operator needs to manually turn the handle and confirm whether the motor current phase sequence matches the tilting direction through repeated trial tilting. Since the tilting directions of different torpedo ladles may be opposite and the motor current phase sequence is unknown, the operator needs to rely on experience and memory, and is prone to tilting errors due to confusing the directions, resulting in molten iron spillage accidents.

[0003] In the prior art, the trial tilting process completely relies on manual operation and lacks an automatic judgment mechanism. The operator needs to observe the tilting direction of the torpedo ladle on site and manually adjust and reset it, with low efficiency and low fault tolerance. Especially in the scenario of multiple railway lines, the lines where the torpedo ladles are located are different, further increasing the operation complexity. The limitations of manual judgment lead to frequent safety hazards. Therefore, there is an urgent need for a trial tilting method for torpedo ladles to solve the above-mentioned problems. Summary of the Invention

[0020] When the difference between the absolute value of the second tilting angle and the second preset angle is less than or equal to the preset angle threshold, it is determined that the second tilting angle is normal;

[0021] When both the first tilting angle and the second tilting angle are normal, it is determined that the tilting angle result is normal.

[0022] In some embodiments, the first preset angle is determined based on the first preset time and the preset tilting speed.

[0023] In some embodiments, obtaining the trial swing result based on the tilting direction result and the tilting angle result includes:

[0024] When the tilting direction result is forward or reverse, and the tilting angle result is normal, it is determined that the trial swing result is qualified, and the tapping operation of the torpedo ladle is allowed to be performed;

[0025] In the case where the tipping direction result is abnormal or the tipping angle result is abnormal, it is determined that the trial swing result is unqualified, and the tapping operation of the torpedo ladle is prohibited.

[0026] In some embodiments, it further includes:

[0027] In the case where the trial swing result is unqualified, an equipment abnormality alarm signal is generated and the abnormal information is recorded, where the abnormal information includes abnormal tipping direction, excessive tipping angle deviation, and failure of the torpedo ladle to reset.

By accurately judging the tipping angle and direction of the torpedo ladle, it effectively solves the problem that different tipping directions during pouring after multiple torpedo ladle cars are powered on are likely to cause molten iron spilling accidents. During the trial swing process, not only can the correct tipping direction be determined, but also by comparing the actual tipping angle with the preset angle, it can be judged whether the equipment is operating normally. When the trial swing result is unqualified, an alarm signal is automatically generated, the abnormal information is recorded, and the pouring operation permission is locked, avoiding potential safety hazards caused by equipment failures. In addition, this method can be automatically implemented, improving the automation level of the pouring process, reducing the complexity and error rate of manual operations, thereby enhancing the safety and reliability of the pouring process and ensuring the smooth progress of steel production.

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0042] Please refer to Figure 1 , which is a schematic flow chart of a method for trial shaking of a torpedo ladle provided by an embodiment of the present application, and specifically may include:

[0043] S110. Determine the tipping direction result of the torpedo ladle based on the tipping angle of the torpedo ladle, where the tipping angle includes a first tipping angle and a second tipping angle;

[0044] Exemplarily, the tipping direction result of the torpedo ladle is determined by analyzing its tipping angle data, where the tipping angle includes a first tipping angle and a second tipping angle. The first tipping angle is collected by an inclinometer after controlling the torpedo ladle to perform a forward tipping action and maintaining it for a preset time; the second tipping angle is collected after resetting the torpedo ladle to the initial position, performing a reverse tipping action and maintaining it for a preset time. These two angles respectively reflect the actual tipping states of the torpedo ladle during forward and reverse tipping, providing basic data for subsequent direction judgment.

[0045] S120. Determine the tipping angle result of the torpedo ladle based on the tipping angle and the preset angle;

[0046] Exemplarily, the tipping angle result of the torpedo ladle is determined by comparing the actual tipping angle with the preset angle. The preset angle is calculated based on the preset time and the standard tipping speed, corresponding to the expected angles for forward and reverse tipping respectively. The actual tipping angle collected by the inclinometer is compared with the preset angle to determine whether the tipping action is within the allowable deviation range.

[0047] The determination of the tipping angle result is based on a preset angle threshold. If the difference between the actual tipping angle and the preset angle is less than or equal to the preset threshold, the tipping angle is determined to be normal; otherwise, it is determined to be abnormal. This mechanism can effectively detect whether the mechanical state of the tipping mechanism of the torpedo ladle is normal, ensure the accuracy and stability of the tipping action, and avoid the risk of molten iron spilling due to excessive angle deviation.

[0048] S130. Obtain the trial tipping result based on the tipping direction result and the tipping angle result.

[0049] Exemplarily, the determination of the trial tipping result is based on a comprehensive judgment of the tipping direction result and the tipping angle result. The tipping direction result determines whether the actual tipping direction of the torpedo ladle is consistent with the preset direction through positive and negative value logic, while the tipping angle result verifies the accuracy of the tipping action through the deviation between the actual tipping angle and the preset angle. Only when the tipping direction is normal and the tipping angle is normal, the trial tipping result is determined to be qualified and the ladle pouring operation is allowed. If the tipping direction is abnormal or the tipping angle is abnormal, the trial tipping result is determined to be unqualified, and the system will prohibit the ladle pouring operation and trigger the equipment inspection process. This mechanism ensures that both the direction and angle of the torpedo ladle tipping action conform to the preset logic through automated judgment and safety control, avoiding molten iron spilling accidents caused by wrong direction or angle deviation, and improving the safety and reliability of the ladle pouring process.

[0050] In summary, through the automated trial tilting method and control program of this application, the safety and efficiency of the torpedo ladle pouring operation are improved. First, through the timing control of the forward and reverse tilting actions, combined with the real-time data of the inclinometer, it is automatically judged whether the tilting direction of the torpedo ladle is consistent with the preset direction, and it is verified whether the tilting angle deviation is within the allowable range, effectively avoiding safety accidents caused by human misjudgment. Second, the PLC program is introduced to realize the full-process automatic control, and the tilting instruction is dynamically corrected according to the trial tilting result to ensure that the tapping direction matches the railway line logic. In addition, when the system detects abnormal direction or angle limit, it automatically triggers an alarm and locks the operation permission, and forcibly requires equipment maintenance, further reducing the risk. This application not only reduces manual intervention, but also improves the safety and reliability of the pouring process through accurate mechanical state detection and closed-loop control.

[0051] As Figure 2 shown, it is a schematic diagram of the tilting direction of the torpedo ladle of this application. In the steel smelting production process, the pouring station is a key place in the molten iron transportation and treatment link. There are two railway lines in the pouring station, marked as Line 1# and Line 2# respectively, and these two railway lines undertake the important task of transporting the torpedo ladle car. An opening is specially set in the middle of the two railway lines, and the design of the opening position is to meet the technological requirements of molten iron receiving. During production operations, the molten iron car is accurately parked under the opening for the purpose of receiving the molten iron poured out of the torpedo ladle.

[0052] However, this layout makes the tilting direction of the torpedo ladle during tapping uncertain. Specifically, the tilting direction of the torpedo ladle during tapping will vary depending on the railway line it is located on. For example, when the torpedo ladle is on Line 1#, its tilting direction is counterclockwise to accurately pour the molten iron into the molten iron car below; similarly, for the torpedo ladle on Line 2#, its tilting direction is clockwise.

[0053] In addition, the unknown phase sequence of the torpedo ladle motor current further exacerbates the uncertainty of the tapping tilting direction. In a three-phase AC motor system, the current phase sequence determines the rotation direction of the motor, which in turn affects the tilting direction of the torpedo ladle. Due to the unknown motor current phase sequence, before the pouring operation, the operator cannot accurately know in which direction the torpedo ladle will tilt.

[0054] If the pouring operation is carried out rashly in this situation, there is a high probability of serious problems such as incorrect tilting direction. Once the tilting direction is incorrect, the molten iron will not be accurately poured into the molten iron car, which may cause the molten iron to spill, not only resulting in waste of molten iron, but also triggering safety accidents such as equipment damage and personnel scalding, posing a great threat to the smooth progress of production and personnel safety.

[0055] Therefore, in order to ensure that the torpedo ladle can tilt to pour out molten iron in the correct direction and guarantee the safety and smoothness of the ladle pouring operation, the operation step of "trial tilting" is particularly necessary. Through "trial tilting", the relationship between the motor current phase sequence and the tilting direction of the torpedo ladle can be effectively determined, so as to clarify the correct tilting direction for pouring out molten iron and avoid a series of adverse consequences caused by the wrong direction.

[0056] In some examples, the step of obtaining the tilting angle of the torpedo ladle includes:

[0057] Controlling the torpedo ladle to perform a forward tilting action for a first preset time, and collecting the forward tilting angle as the first tilting angle through an inclinometer;

[0058] After controlling the torpedo ladle to reset to the initial position, performing a reverse tilting action for a second preset time, and collecting the reverse tilting angle as the second tilting angle through an inclinometer;

[0059] Wherein, the forward direction is the direction of clockwise rotating the torpedo ladle when looking from point A to point B; the reverse direction is the direction of counterclockwise rotating the torpedo ladle when looking from point A to point B.

[0060] Exemplarily, in the operation process of the torpedo ladle, accurately obtaining the tilting angle is a crucial link, the purpose of which is to determine the tilting direction of the torpedo ladle and judge whether the tilting angle is normal, so as to ensure the safety and accuracy of the subsequent ladle pouring operation. Before that, the torpedo ladle needs to meet conditions such as "torpedo ladle alignment", "hot metal car at the tapping position", "power connected", etc., to ensure that it is in a suitable state for the trial tilting operation.

[0061] The tilting angle of the torpedo ladle is obtained by performing forward and reverse tilting actions in stages. First, control the torpedo ladle to perform a forward tilting action for a first preset time. During this process, the inclinometer collects the forward tilting angle in real time as the first tilting angle. The forward tilting is defined as the clockwise rotation direction of the torpedo ladle from the perspective of point A to point B, and this direction is consistent with the preset logic of the motor current phase sequence. By limiting the tilting time and collecting angle data, the actual tilting state of the torpedo ladle under the forward action can be quantified, providing reference data for subsequent direction determination.

[0062] After completing the forward tilting, control the torpedo ladle to reset to the initial position (i.e., the position where the inclination angle is 0° when the torpedo ladle mouth is upward) to ensure that the mechanical mechanism returns to its place. Subsequently, perform a reverse tilting action for a second preset time, and collect the reverse tilting angle as the second tilting angle through an inclinometer. The reverse tilting is defined as the counterclockwise rotation direction from the perspective of point A to point B, and its direction is opposite to the forward action. Through the sequential control of the forward and reverse tilting actions, the tilting behavior characteristics under different current phase sequences can be separated, eliminating the limitations of single-direction testing.

[0063] The inclinometer records the positive and negative signs of the angle values during the forward and reverse tipping processes respectively. A positive forward tipping angle indicates that the clockwise rotation meets the expectation, and a negative reverse tipping angle indicates that the counterclockwise rotation conforms to the preset logic. By comparing the sign relationship of the forward and reverse tipping angles, the matching between the motor current phase sequence and the actual tipping direction can be directly mapped, thus providing a core basis for automatically judging the abnormality of the tipping direction. This process replaces the randomness and uncertainty of manual trial shaking through standardized motion control and data acquisition, ensuring the accuracy and repeatability of obtaining the tipping angle.

[0064] It should be noted that in the embodiments of the present application, the first preset time and the second preset time can be set to 2 to 4 seconds. As Figure 2 shown, the forward direction is the direction of clockwise rotating the torpedo ladle when looking from point A to point B. In the actual operation environment, it can also be the direction of clockwise rotating the torpedo ladle when looking from north to south; or the direction of clockwise rotating the torpedo ladle when looking from the operator's perspective towards the center of the torpedo ladle; or the direction of clockwise rotating the torpedo ladle when looking from the head of the torpedo ladle towards the tail of the torpedo ladle.

[0065] In some examples, determining the tipping direction result of the torpedo ladle based on the tipping angle of the torpedo ladle includes:

[0066] When the first tipping angle is positive and the second tipping angle is negative, it is determined that the actual tipping direction of the torpedo ladle is consistent with the preset direction, and the tipping direction is determined to be forward;

[0067] When the first tipping angle is negative and the second tipping angle is positive, it is determined that the actual tipping direction of the torpedo ladle is opposite to the preset direction, and the tipping direction is determined to be reverse;

[0068] When the signs of the first tipping angle and the second tipping angle are the same, it is determined that the tipping direction is abnormal, and the equipment inspection process is triggered;

[0069] Among them, the preset direction is the tipping direction set according to the tapping logic of the railway line where the torpedo ladle is located and the relationship of the motor current phase sequence.

[0070] Exemplarily, the determination of the tipping direction result of the torpedo ladle is based on the comparison relationship of the inclination angle signs of the forward and reverse tipping actions. Specifically, when the torpedo ladle performs a forward tipping action, if the first tipping angle is positive and the second tipping angle generated by the reverse tipping action is negative, it indicates that the actual tipping direction of the torpedo ladle is consistent with the preset direction. The preset direction here is preset according to the corresponding relationship between the tapping logic of the railway line where the torpedo ladle is located and the motor current phase sequence.

[0071] If the first tipping angle is negative and the second tipping angle is positive, it indicates that the actual tipping direction is opposite to the preset direction. This situation is usually caused by the incorrect phase sequence of the motor current, that is, the actual rotation direction of the motor does not match the preset phase sequence. For example, if the preset direction is clockwise, but the torpedo ladle is driven to tip counterclockwise due to the incorrect phase sequence of the motor, the system determines the direction as reverse at this time, and it is necessary to correct the current phase sequence or adjust the control logic to ensure the accuracy of subsequent operations.

[0072] When the signs of the first tipping angle and the second tipping angle are the same, the system determines that the tipping direction is abnormal. This abnormality may be caused by the confusion of the motor current phase sequence (the phase sequence of the positive and negative tipping actions is not correctly switched, resulting in the tipping direction not flipping as expected), mechanical mechanism failure (the tipping transmission components are stuck or damaged, resulting in the torpedo ladle unable to perform the reset or reverse action according to the instruction), and sensor error (the data acquisition of the inclinometer is abnormal and cannot accurately reflect the actual tipping angle).

[0073] After the system determines the abnormality, it immediately triggers the equipment inspection process, including automatically locking the ladle tipping permission, generating an alarm signal and recording the specific type of abnormality, and forcing manual intervention for maintenance, so as to avoid the risk of molten iron spilling caused by equipment failure. This determination logic realizes the high-precision automatic verification of the tipping direction through the strict comparison of positive and negative signs and the dynamic matching with the preset direction, replacing the subjectivity and uncertainty of the traditional manual trial swing.

[0074] In some instances, based on the tipping angle and the preset angle, the tipping angle result of the torpedo ladle is determined, including:

[0075] When the difference between the absolute value of the first tipping angle and the first preset angle is less than or equal to the preset angle threshold, it is determined that the first tipping angle is normal;

[0076] When the difference between the absolute value of the second tipping angle and the second preset angle is less than or equal to the preset angle threshold, it is determined that the second tipping angle is normal;

[0077] When both the first tipping angle and the second tipping angle are normal, it is determined that the tipping angle result is normal, where the first preset angle is determined based on the first preset time and the preset tipping speed; the second preset angle is determined based on the second preset time and the preset tipping speed.

[0078] Exemplarily, during the trial tilting process of the torpedo ladle, the basis for judging the tilting angle result lies in setting reasonable preset angles. The first preset angle and the second preset angle are determined based on the first preset time, the second preset time, and the preset tilting speed respectively. Among them, the preset tilting speed is set according to the theoretical tilting rate during the normal operation of the torpedo ladle, and its general value range is 2 to 4 degrees per second. The first preset time and the second preset time generally take values between 2 and 4 seconds, and these two times are the durations for controlling the forward and reverse tilting of the torpedo ladle during the trial tilting operation. By multiplying the preset time by the preset tilting speed, the tilting angles that the torpedo ladle should reach within the corresponding time under ideal conditions can be obtained, that is, the first preset angle and the second preset angle, which are used as the benchmarks for judging whether the actual tilting angle is normal.

[0079] For the first tilting angle, when the absolute value of the difference between it and the first preset angle is less than or equal to the preset angle threshold, the first tilting angle is judged to be normal. The preset angle threshold is 1 degree. As long as the difference between the two is within this threshold range, it can be considered that the first tilting angle is within the normal fluctuation range, indicating that during the forward tilting operation, the working states of equipment such as the tilting mechanism and the inclinometer of the torpedo ladle are normal and can tilt at the expected rate and direction. Similarly, for the second tilting angle, when the absolute value of the difference between it and the second preset angle is less than or equal to the preset angle threshold, the second tilting angle is judged to be normal, which means that the equipment is also in a normal working state during the reverse tilting operation.

[0080] Only when both the first tilting angle and the second tilting angle are judged to be normal can the tilting angle result be determined to be normal. This is because only when the tilting angles in both the forward and reverse directions meet the expectations can it comprehensively illustrate that the working states of the tilting mechanism and the inclinometer and other related equipment of the torpedo ladle are stable and accurate during the entire trial tilting process, and can provide reliable angle data support for the subsequent tapping operation. If any one of the tilting angles is abnormal, it may mean that there are faults or abnormal conditions in the equipment, such as mechanical wear of the tilting mechanism, measurement deviation of the inclinometer, etc. At this time, further inspection and maintenance of the equipment are required to ensure the safe progress of the tapping operation. Through this strict judgment logic, abnormal conditions of the equipment can be effectively screened out, ensuring the normal operation of the torpedo ladle and the smooth progress of production.

[0081] In some instances, based on the tilting direction result and the tilting angle result, the trial tilting result is obtained, including:

[0082] When the tilting direction result is forward or reverse and the tilting angle result is normal, the trial tilting result is judged to be qualified, and the tapping operation of the torpedo ladle is allowed to be performed;

[0083] If the tipping direction result is abnormal or the tipping angle result is abnormal, it is determined that the trial swing result is unqualified, and the torpedo ladle tapping operation is prohibited.

[0084] Exemplarily, the determination of the trial swing result is based on a comprehensive judgment of the tipping direction result and the tipping angle result. The tipping direction result determines whether the actual tipping direction of the torpedo ladle is consistent with the preset direction through the positive and negative sign relationship between the first tipping angle and the second tipping angle, while the tipping angle result verifies the accuracy of the tipping action through the deviation between the actual tipping angle and the preset angle. Only when the tipping direction result is positive or negative and the tipping angle result is normal, the trial swing result is determined to be qualified and the torpedo ladle tapping operation is allowed.

[0085] If the tipping direction result is abnormal or the tipping angle result is abnormal, it is determined that the trial swing result is unqualified, and the system will prohibit the torpedo ladle tapping operation. This mechanism ensures that both the tipping direction and the tipping angle of the torpedo ladle conform to the preset logic through automated judgment and safety control, avoiding molten iron spillage accidents caused by incorrect direction or angle deviation.

[0086] The determination process of the trial swing result realizes full-process automated control through the PLC program. In the case of an unqualified trial swing result, the system automatically generates an equipment abnormality alarm signal, records the abnormality information, and at the same time locks the tilting operation permission of the torpedo ladle until manual intervention completes equipment maintenance and resets the trial swing process. This design not only improves the safety and reliability of the tilting process but also significantly reduces the complexity and misjudgment risk of manual intervention.

[0087] In some instances, it also includes:

[0088] In the case of an unqualified trial swing result, an equipment abnormality alarm signal is generated and the abnormality information is recorded, where the abnormality information includes abnormal tipping direction, excessive tipping angle deviation, and failure of the torpedo ladle to reset;

[0089] Based on the abnormality information, the tilting operation permission of the torpedo ladle is locked until manual intervention completes equipment maintenance and resets the trial swing process.

[0090] Exemplarily, when the trial rocking result is determined to be unqualified, the safety guarantee measures are immediately activated. An unqualified trial rocking result means that there are abnormal conditions in key aspects such as the tipping direction or tipping angle of the torpedo ladle, and it cannot meet the requirements for safe pouring. At this time, generating an equipment abnormal alarm signal is a very necessary measure. This alarm signal can convey the information that there is a problem with the equipment to the operator in a timely and intuitive manner, enabling them to quickly detect and pay attention, and avoiding dangerous pouring operations due to ignorance. At the same time, record the abnormal information, which includes key contents such as abnormal tipping direction, excessive deviation of tipping angle, and failure of the torpedo ladle to reset. Recording this information helps the operator and maintenance personnel to comprehensively and accurately understand the specific situation of the equipment abnormality, providing detailed and reliable basis for subsequent fault troubleshooting and maintenance work.

[0091] The recording and analysis of abnormal information have important guiding significance for locking the pouring operation permission of the torpedo ladle. Based on the recorded abnormal information, the system can clearly judge that there is a problem with the equipment. At this time, locking the pouring operation permission is a mandatory safety protection measure. It fundamentally prevents the possibility of pouring operation under abnormal equipment conditions, avoiding serious consequences such as molten iron spilling, equipment damage, and even casualties caused by equipment failure. By locking the permission, the start of the pouring operation is strictly restricted after the equipment returns to normal, ensuring the safety and reliability of the operation.

[0092] After locking the pouring operation permission, the permission lock will not be lifted until manual intervention completes the equipment maintenance and resets the trial rocking process. Manual intervention is the key link to ensure the normal operation of the equipment. The maintenance personnel can conduct a comprehensive and detailed inspection and maintenance of the equipment targeted according to the recorded abnormal information, troubleshooting and solving problems such as chaotic phase sequence of motor current, tipping mechanism failure, and inclinometer deviation. After completing the maintenance, reset the trial rocking process and conduct a trial rocking operation on the torpedo ladle again to verify whether the equipment has returned to normal. Only when the trial rocking result is qualified and it is confirmed that the equipment can operate safely and stably, the lock of the pouring operation permission will be lifted, allowing subsequent pouring operations, thus ensuring the safety and orderliness of the pouring link in the entire iron and steel production process.

[0093] The technical solution of the present application will be further described in detail through specific embodiments below.

[0094] In the application embodiment, it is set that both the forward trial rocking time T1 and the reverse trial rocking time T2 are 3 seconds, and the preset tipping speed ω is 2 degrees per second. The specific steps of this trial rocking method are as follows:

[0095] Determine the trial swing conditions: When the torpedo ladle has the three key signals of "torpedo ladle alignment", "hot metal car in the tapping position", and "power connected", and the operator clicks the "trial swing" button on the screen, the trial swing process officially begins. This step is a prerequisite for the entire trial swing operation. Only when these conditions are met, the subsequent trial swing operation is meaningful and can ensure the testing of the torpedo ladle under appropriate scenarios.

[0096] Control the torpedo ladle to perform a forward tipping action for a duration of 3 seconds. During this process, the forward tipping angle is collected by an inclinometer installed on the torpedo ladle, and the final forward tipping angle obtained is 6.5°. This angle is an important data for judging the forward tipping situation of the torpedo ladle and provides a basis for subsequent analysis. After completing the forward tipping operation, reset the torpedo ladle to the 0 position. This operation is to ensure the accuracy and consistency of the subsequent reverse tipping operation, return the torpedo ladle to its initial state, and facilitate the reverse tipping test. After the torpedo ladle is reset, perform a reverse tipping action for 3 seconds as well. Use the inclinometer to collect the reverse tipping angle, and the obtained angle is -6.3°. This angle is used together with the forward tipping angle to judge the tipping direction and overall state of the torpedo ladle. After the reverse tipping operation is completed, reset the torpedo ladle to the 0 position again to prepare for the subsequent result judgment and analysis.

[0097] According to the tipping angles obtained from the trial swing, the angle a obtained by swinging the hot metal ladle forward is 6.5° (positive value), and the angle b obtained by swinging the hot metal ladle backward is -6.3° (negative value). According to the established judgment rules, it is determined that the actual tipping direction of the torpedo ladle is consistent with the preset direction, and the direction judgment result is "forward". This indicates that under the current motor current phase sequence and equipment state, the tipping direction of the torpedo ladle meets the expectations.

[0098] Compare the collected forward tipping angle a with the tipping angle a0 (a0 = 2×3 = 6°) calculated based on the preset time and preset tipping speed, and calculate the absolute value of the difference between the two, that is, ||a| - a0| = ||6.5| - 6| = 0.5, 0.5 ≤ 1. From this, it is judged that the forward tipping angle is normal; similarly, compare the reverse tipping angle b with the tipping angle b0 (b0 = 2×3 = 6°), and calculate the absolute value of the difference ||b| - b0| = ||-6.3| - 6| = 0.3, 0.3 ≤ 1. It is determined that the reverse tipping angle is also normal. Since both the forward and reverse swings of the hot metal ladle are "normal tipping angles", it is comprehensively judged that the hot metal ladle has a "normal tipping angle". When both the tipping direction and tipping angle are normal, it indicates that the performance of the torpedo ladle meets the requirements, and the pouring operation can be carried out.
