我国型钢轧机的布列以横列式为最多。横列式轧机轧辊配置孔型的个数,主要是受辊环强度的限制(实际是辊环宽度尺寸问题),不能配置过多。而我们为了减少换辊、换孔型次数以提高轧机作业率,合理分配各机架的道次,以提高轧机能力,减少轧辊消耗以降低钢材产品成本,往往与有限的辊身长度不能配置足够的孔型个数发生矛盾。所以,合理设计辊 China’s steel rolling mill in order to rank up to. The number of rows of mill roll arrangement is mainly limited by the strength of the roll ring (in fact, the roll width size problem), can not be configured too much. However, in order to reduce the number of roll change and hole change to improve the rolling mill operating rate and allocate the passes of each rack reasonably, we can improve the rolling mill capacity and reduce the roll consumption to reduce the cost of steel products, often with limited length of the roll body can not be configured enough The number of holes contradictions. So, reasonable design roller
