中厚板轧制过程中宽度控制技术研究


打开文本图片集

摘 要:针对中厚钢板轧制展宽过程中呈现的不规则形状提出了PVPC轧制法,以期达到控制板型提高成材率的目的;针对极限规格板坯无法正常展宽的情况提出了角轧工艺,在提高成材率的同时扩展了产品的供货尺寸范围。

Abstract:This paper suggest PVPC rolling method for the present irregular shape in the process of the medium thick steel plate broadside rolling, in order to achieve the goal of control board type to improve the rate of finished products; angle rolling technology was proposed for the extreme dimension slab can't normal broadside rolling, expand the supply size range of the product. while to improve the rate of finisheg products.

Key words:medium thick steel plate;PVPC rolling;angle rolling

在传统的中厚钢板轧制过程中,横轧阶段一般处于自由展宽状态,输出钢板板型侧边呈现枣核型或头尾呈现舌型等不规则形状,导致后续精整切定尺齐四边工序产生较大的边角余料损失(约占10%~12%)。(剩余1617字)
