Automatic control device and automatic control method used when abnormality occurs in continuous casting production

Abstract

The automatic control device and automatic control method used when abnormality occurs in continuous casting production, including the main control system of the casting machine, the steel breakout forecast system, the casting strand fault information system, the liquid level detection information system and the automatic pouring information system. These information systems are related to a The abnormal casting flow control PLC module is connected to the signal, and the detection information obtained by each is transmitted to the abnormal casting flow control PLC module for processing and judgment. Finally, the module feeds back the processing results to the main control system of the casting machine to automatically control the follow-up actions of the casting machine . The present invention can effectively prevent and control all kinds of sudden abnormalities in the automatic pouring process. The specification of complex and prone to operating errors in continuous casting production can play a very important role in the prevention and control of frequent breakouts, stagnant slabs, rising and other vicious accidents in continuous casting production.

Description

technical field [0001] The invention relates to a control method in the production process, in particular to a process control method applied to slab continuous casting machine equipment. Under automatic production conditions, when the abnormality of the casting machine occurs, in order to prevent the abnormal Guarantee the abnormal identification of subsequent pouring, temporary emergency treatment system and automatic control method to reduce process impact. Background technique [0002] At present, there are continuous casting production lines in every iron and steel production enterprise. The continuous casting production of steel is continuous production. However, in the actual production process, various abnormal situations of continuous casting production can be seen at any time. Sudden abnormalities can easily lead to production interruption, and even lead to malignant production accidents in serious cases, bringing serious harm to the logistics control, equipment ma...

AI Technical Summary

Problems solved by technology

[0011] In order to solve the problem that when the continuous casting production in the prior art is abnormal, only one step of control is required to stop it in the actual application process, and the operator needs to carry out follow-up control in time, otherwise it will lead to the expansion of the accident.
