八钢中厚板机组轧制3100mm宽幅桥梁钢生产实践

Production Practice of Rolling 3100mm Wide Bridge Steel in Medium Plate Mill of Bayi Steel

八钢中厚板机组生产宽度极限为3000mm。为满足市场的需求和提升产品市场竞争力,中厚板厂结合生产和设备情况轧制了3100mm宽幅的桥梁钢。文章介绍了极限宽板生产控制的难点和重点以及极限宽度拓展的生产实践。

The limit of production width of medium and heavy plate mill in Bayi Steel is 3000mm. In order to meet thedemand of the market and enhance the competitiveness of the products in the market, the medium and heavy plate millrolled 3100 mm wide bridge steel according to the production and equipment conditions.This paper introduces thedifficulties and key points in the production control of the limit wide plate, and the production practice of limiting widthexpansion.
