Description

Technical Field

[0001] This application relates to the technical field of cold-rolled strip finishing equipment in the metallurgical industry, and in particular to a method for load distribution of tension rollers and related equipment. Background Technology

[0002] During the operation of the tension roller assembly, torque control is achieved through the tension roller assembly itself. Therefore, it is necessary to assign an appropriate torque setting to each roller to achieve effective tension control.

[0003] The existing method for determining the load distribution factor is based on the power of each roll and the strip wrap angle. Specifically, it's based on the rated power of each roll motor in the tension roll group and the strip wrap angle. The effective wrap angle of each roll is calculated by dividing the wrap angle by 360°. The rated power of each roll motor is multiplied by the effective wrap angle to obtain the effective power of each roll. The ratio of the effective power of each roll to the total effective power of the tension roll group yields the load distribution factor.

[0004] However, existing load distribution methods involve the rated power of each roller, meaning that motors with higher power output torque, and the output torque is unbalanced among the motors, with the motor with higher power always outputting the most force. In other words, when the tension in the tension areas on both sides of the tension roller changes, the load distribution coefficient of the tension roller cannot be adapted accordingly. If the tension setting value of the tension roller is too large, this can easily lead to slippage during the operation of the roller group.

[0005] Therefore, it is necessary to propose a load distribution method for tension roller groups to solve the above problems. Summary of the Invention

[0044] The present application provides a tension roller group load distribution method. The original load distribution method involves the rated power of each roller, that is, the motor output torque is large when the power is large, and the output torque between the motors is unbalanced. The power of the motor with large power is always particularly large, and if the tension setting value of the tension roller is large, the problem of easy slipping phenomenon occurs. The present application is based on Euler formula, . In the application of calculating the friction force between the tension roller and the strip steel, it is embodied that the friction force Where f is the applied external force, k is the friction coefficient, ɑ is the wrap angle of the strip steel on the tension roller, and e is the natural logarithm.

[0045] Specifically, in the tension control equipment of the tension leveling machine area, the No. 7 tension roller of the No. 7 galvanizing line is a tension roller group consisting of four rollers, and it is the tension control equipment for the tension leveling machine area. During the operation of the production line, the currently used No. 7 tension roller group has a problem in load distribution, resulting in excessive torque output from roller No. 2, while the torque distribution to rollers No. 1, No. 3, and No. 4 is insufficient. This situation causes roller No. 2 to slip very easily during operation, triggering an alarm and ultimately causing the production line to stop. To solve this problem, this application provides a load distribution method for the tension roller group, which redistributes the torque settings of each roller in the tension roller group, that is, through design and calculation, the load distribution coefficient of each roller in the tension roller group is obtained. The purpose of this is to achieve a balanced output of each roller and eliminate the occurrence of roller slippage accidents caused by unreasonable load distribution.

[0046] Please see Figure 1 This is a schematic flowchart of a tension roller load distribution method provided in an embodiment of this application, which may specifically include:

[0047] S110: Obtain the basic parameters of the current tension roller group.

[0048] In some examples, the basic parameters include the strip wrap angle of the tension roll, the tension setting value of the inlet side region of the tension roll group, and the tension setting value of the outlet side region of the tension roll group.

[0049] For example, such as Figure 2 As shown, the strip wrap angle α of each roll and the tension setting value of the inlet side region of the tension roll group are known. ), tension setting value of the outlet side area ( ) and other parameters are used to calculate the stress on each roller. / / ... / / n is the number of rollers in the tension roller group, and n≥2.

[0050] S120. Based on the basic parameters and combined with logarithmic and exponential functions, the force values ​​of each roller in the current tension roller group are calculated.

[0051] For example, based on the application of Euler's formula in the calculation of friction between tension roll and strip, combining the logarithmic function y=ln(x) and the exponential function y=exp(x)=ex, using parameters such as the strip wrap angle and the tension setting values ​​of the front / rear regions of the tension roll group, the ratio of the tension setting value of the inlet side region to the tension setting value of the outlet side region of the tension roll group is logarithmically calculated (y=ln(x)), and then multiplied by the proportion of the strip wrap angle of this roll. The product is then exponentially calculated (y=exp(x)=ex). The product of the result and the force on the front roll is the force situation of this roll.

[0052] S130、based on the force value of each roller in the current tension roller group and the basic parameter, the load distribution coefficient of each roller in the current tension roller group is calculated to distribute the torque setting value of each roller in the current tension roller group.

[0053] For example, according to the force calculation result of each roller, the difference between the tension setting value of the tension roller group inlet side region and the force of each roller itself The difference between the tension setting value of the tension roller group inlet side region and the tension setting value of the outlet side region is divided by the difference between the tension setting value of the tension roller group inlet side region and the tension setting value of the outlet side region. The quotient obtained is the load distribution coefficient of each roller.

[0054] In some examples, based on the basic parameter, the force value of each roller in the current tension roller group is calculated by combining the logarithmic function and the exponential function, including:

[0055] According to the tension setting value of the tension roller group inlet side region and the tension setting value of the outlet side region, a target logarithmic function value is obtained;

[0056] According to the logarithmic function value and the strip angle of the current roller, a target exponential function value is obtained;

[0057] According to the exponential function value and the force value of the previous roller of the current roller, the force value of the current roller is obtained.

[0058] For example, the ratio of the tension setting value of the tension roller group inlet side region to the tension setting value of the outlet side region is / The logarithmic function (y=ln(x)) is taken on the above ratio. The value obtained by taking the logarithmic function is multiplied by the proportion of the strip angle of this roller. The exponential function (y=exp(x)=ex) is taken on the product obtained. The product of the result obtained and the force of the previous roller is the force of this roller. The specific calculation formula is as follows (1).

[0059] In some examples, based on the basic parameter, the force value of each roller in the current tension roller group is calculated by combining the logarithmic function and the exponential function, and the specific formula is:

[0060] (1);

[0061] Wherein, is the tension setting value of the tension roller group inlet side region, is the tension setting value of the tension roller group outlet side region, is the force of the No. 1 roller in the tension roller group, is the force of the No. 2 roller in the tension roller group, is the force of the No. (n-2) roller in the tension roller group, The force on roller (n-1) within the tension roller group. The force on roller n within the tension roller group. The wrap angle of the strip on roll 1 within the tension group. The wrap angle of the strip on roll number 2 within the tension group. The wrap angle of the strip on roll n-1 within the tension group. This refers to the wrap angle of the strip on roll n within the tension group.

[0062] In some examples, based on the force values ​​of each roller in the current tension roller group and the basic parameters, the load distribution coefficient of each roller in the current tension roller group is calculated, including:

[0063] The first difference is calculated based on the tension setting value of the inlet side region of the tension roller group and the force value of each roller in the current tension roller group;

[0064] The second difference is calculated based on the tension setting value of the inlet side region of the tension roller group and the tension setting value of the outlet side region of the tension roller group;

[0065] Based on the first difference and the second difference, the load distribution coefficient of each roller is obtained.

[0066] For example, based on the force conditions of each roller calculated using equation (1) above, the load distribution coefficient of each roller in the tension roller group is calculated as follows: / / ... / / ,in + +...+ + =1. Specifically: Calculate the tension setpoint in the inlet area of ​​the tension roller group and the force on each roller itself. The first difference. Calculate the second difference between the tension set value in the inlet side region and the tension set value in the outlet side region of the tension roller group. The quotient obtained by dividing the first difference by the second difference is the load distribution coefficient of each roller, and the specific calculation formula is as follows (2).

[0067] In some examples, the load distribution coefficient of each roller in the current tension roller group is calculated based on the force values ​​of each roller in the current tension roller group and the basic parameters. The specific formula is as follows:

[0068] (2);

[0069] in, This is the load distribution coefficient for roller number 1 within the tension roller group. This is the load distribution coefficient for roller number 2 within the tension roller group. a load distribution coefficient of a (n-1)th roller in the tension roller set, a load distribution coefficient of an nth roller in the tension roller set, a force borne by a 1st roller in the tension roller set, a force borne by a 2nd roller in the tension roller set, a force borne by a (n-2)th roller in the tension roller set, a force borne by a (n-1)th roller in the tension roller set, a tension setting value of a region on an inlet side of the tension roller set, a tension setting value of a region on an outlet side of the tension roller set.

[0070] In some examples, the torque setting values of the rollers in the current tension roller set are distributed, including:

[0071] The load distribution coefficients of the rollers in the current tension roller set are assigned to the tension control system to perform tension distribution.

[0072] For example, the tension distribution application is performed by assigning the load distribution coefficients to the tension control program.

[0073] In summary, the tension roller set load distribution method provided by the present application involves only the tension setting values before and after the tension roller set and the wrap angle of the strip on each roller. The application of the Euler formula in the calculation of the friction force between the tension roller and the strip is different from the traditional tension roller set load distribution. After implementation, the torque of each roller is more balanced, and slipping is less likely to occur. The tension roller set load distribution method provided by the present application has innovation and practicality. After optimization, the load distribution coefficients of each roller are applied to the control program, and the torque output of each roller is more balanced than before. After optimization, there is no slipping phenomenon and strip breakage alarm failure.
