快速换辊就是以尽可能快的速度更换轧机的工作辊和支承辊,在带钢轧制中为了保证最终轧制质量,尤其是在冷轧时对带钢厚度和表面质量要求高,需要经常更换轧机的工作辊。花费在换辊上的时间影响了轧机的产量。在高速热连轧和冷连轧中,这个问题更为突出。采用快速换辊装置后,缩短了换辊时间、增加了轧机的生产时间,从而提高了生产率,一般可以提高产量10％左右。快速换辊 Fast roll change is the fastest possible replacement of the work roll and the backup roll in the strip rolling in order to guarantee the quality of the final rolling, especially in cold rolling, which requires high strip thickness and surface quality, requiring frequent Change the work roll of the mill. The time spent on roll change affected the mill’s production. In high-speed hot strip mill and cold rolling, the problem is more prominent. The use of a quick roll changer shortens the roll change time and increases the mill’s production time, thus increasing productivity and generally increasing production by about 10%. Quick roll change
