一、引言冷轧厂的热处理,主要是冷轧带钢的退火,这种退火是一种再结晶退火,也是它的最终退火。其目的是消除冷轧后引起的加工硬化,使交货状态下的冷轧带钢在深冲和拉伸等后续加工过程中,具有很好的可塑性。冷轧宽带钢绝大部分选用低碳沸腾钢或 I. Introduction Cold rolling mill heat treatment, mainly cold-rolled strip annealing, this annealing is a recrystallization annealing, but also its final annealing. Its purpose is to eliminate the work hardening caused by the cold rolling, so that the cold rolled strip in the delivery state has good plasticity in the subsequent processing such as deep drawing and drawing. Most of the cold-rolled broadband steel used low-carbon steel or boiling
