增大冷轧压下率提高钢板质量

Improving the Quality of Cold Rolled Strip by Increasing Cold Tandem Reduction

经过在生产轧机上的试验研究发现 ,增大冷连轧机的压下率 ,可细化晶粒、降低再结晶温度和进一步降低轧后带钢凸度 ,从而可有效防止粘结的产生。

It is verified by a series of tests on a factory tandem strip mills that increasing pressing rate of cold continuous rolling is contributive to lessen grain and decrease crown and recrystallized temperature, meanwhile, prevent sticking.
