摘要
分析比较了国内某1420冷轧酸洗-轧机联合机组生产产品质量,针对换辊时温差导致轧制的薄板变形量大,对联合机组进行了改进,改进后末架配备了轧辊预热装置,产品质量明显提高。
Analysis and comparison of the domestic cold pickling in a 1420-Combined Unit Mill production quality, the time for roll changing temperature cause large deformation of sheet metal rolling, the joint unit is improved, improved late frame is equipped with roll preheat device Product quality has improved significantly.
