Intelligent rolling mill liquid supply control system

Abstract

The invention belongs to the technical field that: the invention relates to intelligent control, energy consumption reducing and plate shape improvement over a technical lubrication liquid supply system of a cold-rolled steel plate rolling mill. The invention solves the technical problems of poor plate shape, emulsion spots, low first-grade product rate and the like in a fixed liquid supply mode.The technical scheme is as follows: an adopted control system comprises a hardware system and a software system. The hardware system mainly comprises an operation interface, a controller and an actuator. The operation interface has the functions of data acquisition, parameter setting and operation monitoring; the controller has the functions of analyzing and calculating the acquired data and outputting a control signal; and the actuator has the functions of receiving the control signal and outputting a control command to control equipment. The software system mainly comprises an acquisition program and a control program. The acquisition program has the function of acquiring process data of a rolling mill. The control program has the function of performing calculation and judgment accordingto the process data and outputting a control signal. The invention is mainly used for the technical lubrication liquid supply system of the cold-rolled steel plate rolling mill.

Description

technical field [0001] The patent of the invention relates to the intelligent control of the lubricating liquid supply system of the steel plate cold rolling mill process, which reduces energy consumption and improves the shape of the plate. Background technique [0002] The cold rolling mill of the steel plate factory needs continuous liquid supply during the rolling process to lubricate the plate surface, reduce the rolling force, and reduce the temperature of the plate surface. It is the most important auxiliary system in the rolling process of the rolling mill. However, too much liquid supply will cause the plate surface to slip, damage the plate surface, and leave emulsified spots; too little liquid supply will cause excessive rolling force, high temperature of the plate surface, high energy consumption, and easy strip breakage. The optimal liquid supply mode should be to dynamically adjust the liquid supply volume according to the rolling process, but at present, most ...

Problems solved by technology

However, too much liquid supply will cause the plate surface to slip, damage the plate surface, and leave emulsified spots; too little liquid supply will cause excessive rolling force, high temperature of the plate surface, high energy consumption, and easy strip breakage

The optimal liquid supply mode should be to dynamically adjust the liquid supply volume according to the rolling process, but at present, most domestic rolling mills adopt a fixed liquid supply mode, and supply liquid according to the maximum liquid supply volume, which generally has poor plate shape and emulsification spots. The first-class product rate is not high, and it is urgent to carry out intelligent control of the liquid supply system
