In order to improve the capability of strip edge drop control in 1420TCM and develop strip productions such as DI tinplate which demands high quality of edge drop,the special work roll profile and design method were developed,and the parameters of target curve for automatic flatness control in stand 1 were also adjusted.
为了开发提升1420冷连轧机组的带钢边降控制功能,拓展生产DI材等对边降有特殊要求的高端产品,提出了专门用于控制边降的工作辊辊形设计思路与方法,同时专门针对DI材轧制的板形需求,对连轧机第一机架的板形平坦度控制目标曲线进行了修改完善。
DI tinplate was mainly used for drink packaging of carbonic acid and beer.
DI材主要用于碳酸饮料和啤酒的包装,用户对厚度精度有十分苛刻的要求,成品规格DI材距边部5mm外所有点厚度都必须保证在±5μm的范围内。
