高速钢轧辊由于在金相组织有硬质ＭＣ碳化物的分散存在则是高耐磨性轧辊 ,比以前使用的高Ｃｒ铸铁轧辊寿命提高 3～ 5倍 ,所以在热带连轧机工作辊多数使用。近年来 ,为了降低轧制成本提高热带钢表面质量和数量而使轧制负荷增加等 ,使轧辊使用条件和环境更加苛刻 ,则要求进一步 High-speed steel rolls are high-wear-resistant rolls due to the dispersion of hard MC carbide in the metallographic structure. They are 3 to 5 times longer than those of the conventional high-Cr cast iron rolls. Therefore, they are mostly used in work rolls of hot-strip tandem mills. In recent years, in order to reduce the rolling cost and improve the surface quality and quantity of the hot-rolled steel to increase the rolling load and the like, and to make the conditions and the environments of the rolls more severe, it is required to further
