摘　　要：针对轧钢精轧时存在的切割浪费问题,分析了切割浪费的主要构成,建立了使浪费最小的随机优化模型,通过模型求解,在成品材的规定长度和粗轧时钢材长度的均方差已知的条件下,确定了粗轧钢材的长度均值,使得当轧机调整到所求均值时进行粗轧,再通过精轧得到成品材时的浪费是最小的,从而为实现轧钢降耗提供了新的实用途径.In view of the problem of existing waste of steeling in the steel roiling, the influence factors were found out. A mathematic model was established to minimize the waste. When the length of finished product is set and the variance of the length in the roughing process is given, the mean of the length in the roughing process is determined. To make lost be the smallest, only to adjust the rolling mill to the mean which had obtained when In the roughing process, then to finish rolling it. It provided a new effectively way for lowering the steel rolling consumption.
