Abstract

A halting method for scrap steel of hot rolling coilers comprises an automatic coiler halting method and an automatic roller bed halting method. The automatic coiler halting method comprises the following steps: determination is performed according to detection and logic, and when the head of strip steel does not to reach the coilers yet and if a motor of a pinch roll or a winding drum of one coiler trips, the standby state of another coiler is shifted to the using state automatically; and determination is performed based on detection and logic, and when the head of the strip steel is gripped by the coilers and if the motor of a pinch roll or a winding drum of one coiler trips, all the coilers are halted automatically. According to the automatic roller bed halting method, the rolling state is divided into five types, and different roller bed halting processes are selected and executed automatically according to different rolling states and strip steel types. The halting method can perform automatic determination and halt on the scrap steel of the coilers, and adopts different roller bed halting methods according to automatic analysis of a strip steel rolling step, therefore, the strip steel can be accumulated uniformly on the rolling bed, and a scrap steel accident is prevented from expanding.

Description

technical field

[0001] The present invention relates to the field of metallurgical hot rolling. Specifically, the present invention relates to a method for shutting down scrap steel of a hot-rolling coiler. And the solution to the problems of long scrap processing time and accident expansion caused by improper manual shutdown of the front roller table of the coiler. Through the method for shutting down the scrap steel of the hot-rolling coiler of the present invention, the possibility of expansion of the accident caused by the operator's experience, judgment and negligence can be reduced to the minimum. Background technique

[0002] See figure 1 , Generally, the technological process of the hot rolling production line roughly includes heating, rough rolling, finishing rolling, coiling, transportation, finishing and other processes. Wherein, described heating, rough rolling, finish rolling process are as follows:

[0003] First, according to the rolling plan, the slabs are...
