Bar steel full fixed-length intelligent control system and fixed-length control method

Abstract

The invention provides a bar steel full fixed-length intelligent control system and a fixed-length control method. The bar steel full fixed-length intelligent control system comprises a billet weight adjusting system, a blank tracking system, a finished product steel length detecting system, a steel full fixed-length intelligent analyzing system and a steel minus deviation sampling system. The steel minus deviation sampling system carries out sample measuring on samples, measured data is transmitted to the steel full fixed-length intelligent analyzing system to be analyzed, the steel full fixed-length intelligent analyzing system judges whether the final rate of fixed-length reaches the standard or not, if the standard is not reached, the analyzed data is transmitted to the billet weight adjusting system so that the billet weight can be adjusted, the blank tracking system monitors the following procedures of adjusted billets, the finished product steel length detecting system collects and feeds data of finally fixed-length materials back to the steel full fixed-length intelligent analyzing system to judge whether the billet weight needs to be adjusted again or not, and the rate of fixed-length can reach 99.7 %.

Description

technical field [0001] The invention relates to the technical field of billet continuous casting, in particular to an intelligent control system for full-size rods and profiles. Background technique [0002] China's steel industry has developed rapidly in the past 20 years. Iron and steel enterprises have also developed from the original extensive management to refined management. Enterprises' cost awareness and innovation awareness are rapidly increasing. Cost has become the key to whether iron and steel enterprises can survive in the market competition. Steel rolling, as the last process in the steel industry, has a significant impact on corporate profits. The yield rate, negative difference rate, cut-to-length rate, and energy consumption of the steel rolling process are the key to cost control. Due to many influencing factors, difficult control, and recessive influence on benefits, the fixed-to-length rate has not been paid attention to in the early stage. However, ...

AI Technical Summary

Problems solved by technology

② It affects the production rhythm of the finishing process and affects the increase in output. It is difficult to pick short-length materials

③ Increased the difficulty of steel adjustment on the cooling bed

⑥Increased potential safety hazards

⑦ Affect the accuracy of counting

⑧When short-length materials enter the market with fixed-length materials, quality objections will occur, which will affect market sales and corporate reputation

⑨ Seriously affect the intelligent control level of the post-rolling process
