Rolling mill automatic shutdown device, and rolling mill automatic shutdown control system and control method

Abstract

The invention discloses a rolling mill automatic shutdown device, and a rolling mill automatic shutdown control system and control method. The rolling mill automatic shutdown device, and the rolling mill automatic shutdown control system and control method are suitable for a hot continuous rolling technology and mainly aim at solving the problems that after steel heaping of a certain rack of a hotcontinuous rolling mill, manual shutdown operation is improper, accordingly the steel heaping treatment time is long and accidents are expanded. According to the rolling mill automatic shutdown device, and the rolling mill automatic shutdown control system and control method, the strip steel warp waste steel accident can be reduced, automatic judgment of the steel heaping accident is realized, and unnecessary shutdown accidents caused by judgment errors can be avoided. Automatic shutdown after the steel heaping accident is realized. After the steel heaping accident occurs, shutdown is performed in time so as to reduce the steel heaping amount between the heaping racks, and precious steel heaping treatment time is gained.

Description

technical field [0001] The invention relates to the technical field of hot continuous rolling of strip steel, and more specifically refers to a rolling mill automatic shutdown device, a control system and a control method. Background technique [0002] In the roughing area of ​​the hot rolling mill, combined with figure 1 , R3 and R4 stands are continuous rolling stands. When R3 rack 1 conveys strip steel 3 to R4 rack 2, the problem of stacking steel between racks often occurs. R3 rack bites into strip steel 3 and transports the strip steel to R4 rack. Abnormal conditions such as buckle heads cannot be bitten into the R4 rack smoothly, resulting in stacking of steel between the racks. The continuous rolling units of each hot production line need to be manually shut down after steel stacking occurs. Some hot-rolling production lines have added a grating above the side guide plate 4, and when the head is warped or piled up steel, an alarm will be displayed on the operation ...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the steel stacking accident of the above-mentioned prior art continuous rolling mill is one of the frequent accidents in the hot rolling production line, the cause of the steel stacking accident is complicated, and the defect itself is difficult to completely eliminate, the present invention provides a rolling mill automatic shutdown device, control system and The control method, on the one hand, can reduce scrap steel scraps, on the other hand, it can automatically judge and shut down the pile-up accident of the continuous rolling mill, so as to minimize the possibility of the expansion of the accident caused by the operator's experience, judgment and omissions
