Abstract

The invention relates to an intelligent steel rolling accurately-rolled piece tracking and handling method. The intelligent steel rolling accurately-rolled piece tracking and handling method comprises the steps that the linear speedVn of an Nth rolling mill and the linear speed Vn+1of an N+1th rolling mill are acquired; the forward slip coefficientK1of the rolled piece movement speed V0 relative to Vn is acquired; the backward slip coefficient K2of the rolled piecemovement speedV0 relative to Vn+1 is acquired; the scanning perioddelta T of a programmable logic controller (PLC) system is acquired; according to Vn, K1 and delta T, the rolled piece head position P1 is calculated after steel enters the Nth rolling mill; and according to Vn+1, K2 and delta T,the rolled piece tail position P2is calculated when steel is thrown by the rolled mill. By means of the technical scheme of the intelligent steel rolling accurately-rolled piece tracking and handling method, the tracking accuracy of the rolled piece is improved greatly; and requirements for intelligent steel rolling control can be satisfied.

Description

technical field [0001] The invention belongs to the technical field of intelligent steel rolling, and in particular relates to a method for tracking and processing intelligent steel rolling parts accurately. Background technique [0002] The core technologies of traditional rolling line automation control include rolling piece tracking, speed cascading, speed self-adaptation, speed compensation, micro-tension control, looper control, flying shear control, etc. Whether the rolling piece tracking is accurate or not, and how to apply it, is the basis and key to whether the rolling line can realize intelligent control. [0003] In the traditional long product rolling line automation system, the current rolling piece tracking error range is: 100-200mm in the rough rolling area, 500-1000mm in the middle rolling area, and 1500-3000mm in the finishing rolling area. Under such error conditions, it is impossible to precisely control the rolling line, and all rolling lines need manual...
