摘　　要：介绍了一种通过镶铸的铸造方法制备轧辊。这种轧辊的外层为改进型半高速钢材质,内层为无缝钢管,芯轴用圆钢或废钢轧辊车制,通过热装配制造成组合式轧辊。采用这种轧辊轧制Φ12 mm螺纹钢成品单槽过钢量可达到230~260 t,并且在使用过程中未出现裂纹、掉块问题。It is introduced a method to make roll： bushing casting. This roll is made as fellow： outer layer is improved semi H. S. S.,internal layer is seamless steel tube,central spindle is made with round steel or waste steel roll,then composite roll is formed with hot assembly. With this kind of roll,rolling amount per groove for 12 mm deformed steel bar can reach 230 to 260 tons,and there is no problems such as cracks or broken in its usage.
