Detection system for high-speed wire rod steel heaping and judgment method

Abstract

The invention discloses a detection system for high-speed wire rod steel heaping and a judgment method of the detection system. The detection system comprises a PLC control system, detection loops, loop detectors and accident shears. The loop detectors are mounted on the detection loops. The detection loops are correspondingly mounted on a pre-finishing mill group and a finishing mill group of a rolling production line. The loop detectors and the accident shears are connected to the PLC control system through circuits. The detection system for high-speed wire rod steel heaping and the judgment method mainly aim at the steel heaping failure of a segment from a pre-finishing mill to a finishing mill in the large-scale steel rolling process; and in the type of steel heaping failure, the finishing line failure cannot be judged in time, excessive steel heaping is caused, so that whether steel heaping happens or not is judged by detecting the loop quantity between the pre-finishing mill and the finishing mill, accordingly the judgment can be made in advance, the judgment is precise, and the failure treatment time is shortened.

Description

technical field [0001] The invention relates to the technical field of production of steel rolling high-speed wire rod workshops, in particular to a stacked steel detection system and judging method applied to steel rolling high-speed wire rod workshops. Background technique [0002] The main rolling processes of ordinary high-speed wire rod workshops are: rough rolling, intermediate rolling, pre-finishing, finishing area, pinch rolls, and laying machine. There are three to four loopers in the area. The looper is to lift or push the rolling piece to the side during the rolling process, so that there is an arc during the movement of the rolling piece to reduce the tension between the rolling mills. When the looper is set , a looper height will be set on the rolling main screen, that is, the height of the rolled piece, and its height will be detected by a looper scanner. When it is higher than the set height, it means that there is a pile of steel between adjacent rolling mill...

AI Technical Summary

Problems solved by technology

[0003] In the process of rolling, due to various reasons, there will often be piles of steel, which are usually piled up inside the looper. If the fault cannot be found in time, there will be more accumulation in the looper, resulting in a backlog of rolled pieces, which needs to be dealt with. It is very difficult, sometimes it takes nearly 1 hour, and it has a great impact on production. Fishing lines are usually installed in the rolling mills of the pre-finishing and finishing mills. The fault alarm mode is triggered, and the upstream accident shears perform the breaking operation, but at this time the looper is full, so the judgment of the fishing line is often delayed, resulting in prolonged fault processing time
