Intelligent steel rolling abnormal rolling evaluation system and treatment method

Abstract

The invention relates to an intelligent steel rolling abnormal rolling evaluation system. The system is used for replacing manual judgment to judge common rolling abnormal conditions of a long material production line and providing an emergency treatment scheme. The intelligent steel rolling abnormal rolling evaluation system comprises a plurality of rolling mills, a controller, a rolling mill biting steel characteristic analysis module, a rolling mill biting steel time sequence tracking module, a loop height characteristic analysis module and a rolling mill rolling process tension analysis module. The invention further provides an intelligent steel rolling abnormal rolling evaluation method and a treatment method. According to the technical scheme, the long-material rolling line production state can be monitored in real time, when the rolling abnormity occurs or the rolling fault occurs, the controller is used for processing, so that the situation that the manual judgment is not timely is avoided, the occurrence frequency of production accidents and the treatment time during accidents are reduced, and secondary damage of equipment is avoided, so that the safety of the system is enhanced, and the production system has the function of no need manual operation when an emergency circumstances occurs.

Description

technical field [0001] The invention belongs to the technical field of intelligent steel rolling, and in particular relates to an intelligent steel rolling abnormal evaluation system and a processing method. Background technique [0002] Common abnormal rolling in traditional long product rolling line mainly includes the following four situations. [0003] 1. The incoming steel slips. Slipping of incoming steel generally occurs in the environment of new rolls (or new troughs), and the temperature of the rolled piece is low, which leads to slippage in the steel feeding process of the first rolling mill. In the production process of the long product rolling line, if the slippage of the incoming steel occurs, if it is not handled in time, it will affect the production rhythm, and then affect the output and yield of the production line. [0004] 2. Bite steel and run steel. Bite and running steel refers to the occurrence of steel running when the lower rolling mill bites in, ...

AI Technical Summary

Problems solved by technology

In the production process of the long product rolling line, if the incoming steel slips, if it is not handled in time, it will affect the production rhythm, and then affect the output and yield of the production line

[0004] 2. Biting steel and running steel

In the production process of traditional long product rolling line, the phenomenon of biting steel and running steel occurs, which generally affects the output and yield, and in severe cases, it will damage the equipment and cause production accidents

[0005] 3. Flying steel in the looper area

Bending steel in the rough and intermediate rolling area is generally due to unreasonable tension setting or inability to effectively adjust, which leads to serious stacking between adjacent rolling mills in the rough rolling area or intermediate rolling area, which eventually leads to bending and stacking of rolled pieces between adjacent rolling mills, which in turn causes other production accidents

[0007] In the existing long product rolling line production process, there is no effective means to detect these situations, and usually the operator confirms and handles them on the spot, which requires high technical level and attention of the operator
