炉卷轧机生产不锈钢板形控制研究
|
摘要
介绍了酒钢炉卷轧机板形控制技术,包括工作辊弯辊技术(WRB)、连续可变凸度控制技术(CVC)和动态工作辊冷却技术(DWRC)。针对该公司生产1260、1540mm宽轧件易出现猫耳朵,同一辊役连续轧制块数少的问题,对CVC轧辊横移方式、辊型、冷却水流量等进行优化改进。改进后,有效提高了板形控制能力和轧机生产效率。
The profile control of stainless steel strip in Steckel mill of JISCO were introduced,including work roll bending technology(WRB),continuous variable crown control technology(CVC),dynamic work roll cooling technology(DWRC).In view of problems of appearing cat ear and small rolled pieces in roll service life during rolling 1260,1540mm wide stripes,some improvement and optimized measures were used on CVC roll shiftting type,roll type,cooling water flow.Through the comprehensive application of the above techniques,both profile control ability and mill production efficiency were improved.
