Rolling mill loop roller swing rotation angle detection system and control method thereof

Abstract

The invention discloses a rolling mill loop roller swing rotation angle detection system. An operation side and a driving side of a loop roller (4) are provided with encoders respectively. The invention further discloses a control method of the detection system. By adopting the technical scheme, the rolling mill loop encoders which are mutually standby can be quickly put into use through on-line quick switching, and the switching and putting-into-use time is only 5 minutes. Compared with the prior art that it takes 40 minutes to replace the rolling mill loop encoders, the putting-into-use time is greatly shortened, the fault influence time is reduced, and stable and smooth production is guaranteed. The problems of production interruption, continuous casting pulling speed reduction, pouring stopping and the like caused by safety accidents such as rolling mill idle passing and steel piling are avoided, the plan execution rate and the specification fulfillment rate of production are guaranteed, and safe production is achieved.

Description

technical field [0001] The invention belongs to the technical field of steel strip rolling process equipment, and relates to a rolling mill system with looper tension control for strips and the like. More specifically, the present invention relates to a detection system for swing angle of looper rolls in a rolling mill. The invention also relates to a control method of the detection system. Background technique [0002] Rolling mill looper angle control is an important part of rolling mill production. Due to the harsh environment, the rotating shaft of the looper suddenly jumps and moves, and the encoder of the looper is often damaged, which may easily cause the rolling mill to be empty, pile up steel, production interruption, continuous casting speed drop, and pouring stop; while in the prior art, Only the encoder is set on the operating side of the looper roll, once it breaks down, the production efficiency will drop, and even cause a safety accident, which will have a g...

AI Technical Summary

Problems solved by technology

Due to the harsh environment, the rotating shaft of the looper suddenly jumps and moves, and the encoder of the looper is often damaged, which may easily cause the rolling mill to be empty, pile up steel, production interruption, continuous casting speed drop, and pouring stop; while in the prior art, The encoder is only installed on the operating side of the looper roll. Once it fails, the production efficiency will decrease, and even cause safety accidents, which will have a great impact on steel rolling production.
