摘　　要：离心复合铸铁轧辊是一种外硬内韧并且具有很好的使用性能的双金属实心轧辊。为得到这种高性能轧辊,从生产过程中金属铸型的控制、表层金属液的控制、表层金属液和内层金属液浇注间隔时间控制、内层金属液的控制几个方面详述了得到这种高性能轧辊的控制要点。结合286mm×508mm离心复合铸铁轧辊的生产实例,经计算、选定并测量、记录控制要点中的参数,以辊身、辊颈硬度和工作层厚度的测量结果证实了试制轧辊质量控制效果良好。Centrifugal composite cast iron roller is a kind of bimetallic solid roll which has good performance with hard surface and tough core.To obtain the high-performance roller,the controlling keys of the metal mold production process control,surface liquid metal control,interval time of surface liquid metal and inner liquid metal pouring control were described in details.The centrifugal composite cast iron roller with286mm × 508mm was produced successfully.Through calculating,selecting and measuring as well as recording the parameters from the controlling keys,the measured data from hardness of the barrel,roll diameter and work layer thickness confirms the effect of the trial roll quality control.
