Method and device for online predicting and optimizing product quality in steel rolling production process

Abstract

The invention discloses a method and device for online predicting and optimizing product quality in the steel rolling production process, and relates to the technical field of quality prediction and optimization. The method comprises the steps that the data of all steel rolling production processes of a connection site control network are collected, and the current production operation data of all the steel rolling production processes are acquired; current product quality index data corresponding to the current production operation data are predicted according to the current production operation data; preset target product quality index data are compared with the predicted current product quality index data, and the optimal operation conditions of all the steel rolling production process are found out according to the comparison result; the production operation data of all the steel rolling production processes are correspondingly adjusted according to the optimal operation conditions of all the steel rolling production processes, so that the product quality of steel rolling production is optimized. According to the method and device, various operation variables in the product production process are controlled in real time, and products in the steel rolling production process are subjected to real-time and effective quality control and quality optimization.

Description

technical field [0001] The invention relates to the technical field of quality prediction and optimization, in particular to a method and device for online prediction and optimization of product quality in the steel rolling production process. Background technique [0002] In recent years, my country has made great progress in the field of steel rolling, and the technical and economic indicators have been further improved.
