Quality pre-auditing method for cold rolling raw material warehouse

Abstract

The invention provides a quality pre-auditing method for a cold rolling raw material warehouse, and belongs to the technical field of metallurgical automation and big data. The method comprises the following steps: acquiring hot-rolled raw material data through big data, automatically judging the quality of raw materials in a raw material library according to a raw material quality judgment standard, and counting the raw material data in the library. The auditing range can cover data of each meter of all strip steel in the whole raw material library, indexes of quality judgment comprise thickness, width, finish rolling temperature, coiling temperature, convexity and wedge shape of the strip steel, and the strip steel in the raw material library is counted and analyzed according to a quality judgment result. Therefore, production plan arrangement personnel can conveniently avoid unqualified strip steel when arranging a production plan, the production failure rate is reduced, and technicians can visually and integrally master the raw material condition in a reservoir area.

Description

technical field [0001] The invention relates to the field of metallurgical automation and big data technology, in particular to a method for pre-examining the quality of a cold-rolled raw material warehouse. Background technique [0002] As the first process of cold rolling production, the acid rolling production line accepts the materials off-line from the hot rolling production line as raw materials for the acid rolling production line. These materials are mainly stored in two stocks, one is directly stored in the cold rolling raw material warehouse, and the other is It is the finished product warehouse of the hot rolling production line. After the strip steel in the cold-rolled raw material warehouse is arranged through the production plan, it will carry out the cold-rolling production process at a specific time. [0003] The quality of hot-rolled raw materials directly affects the quality of cold-rolled finished products and the efficiency of cold-rolled rolling lines. ...

AI Technical Summary

Problems solved by technology

At this stage, the steel rolling automation technology in steel mills has been very mature, but a series of key technologies such as product quality analysis, production plan reports, and product quality defects still require a lot of manpower and material resources.

This has led to steel mills investing a lot of energy in repetitive and basic work

Due to the low real-time and accuracy of data exchange between hot rolling and cold rolling, it is difficult to conduct a comprehensive review of all raw materials in the raw material warehouse before the production plan is arranged according to the previous technology.
