轧辊的分类方法有多种，主要有：（1）按产品类型分有带钢轧辊、型钢轧辊、线材轧辊等；（2）按轧辊在轧机系列中的位置分有开坯辊、粗轧辊、精轧辊等；（3）按轧辊功能分有破鳞辊、穿孔辊、平整辊等。Therearemanyclassificationmethodslikerollerare:(1)accordingtothetypeofproductwithstriproller,steelroller,wireroller;(2)accordingtotherollinrollingmillseriesintheofdividedbloomingrolls,roughingroll,finishingroll;(3)accordingtothefunctionofarollerdescalingKongGun,wearingroller,flatrolletc.不同类型的轧机以及同类型而使用条件不同的轧机，对所用的轧辊性能要求不尽雷同，如方坯和板坯初轧机轧辊要具有好的扭转和弯曲强度、韧性、咬入性、抗热裂性和热冲击性以及耐磨性；(2)半硬辊：肖氏硬度约为40一60，用于大型、中型、小型型钢轧机和钢板轮机的租轧机。而热带精轧机架要求轧辊辊面的高硬度、抗压痕、耐磨、抗剥落和耐热裂等性能。Differenttypesofrollingmillandthesametypeandtheuseofdifferentconditionpropertiesofrollmill,requirementsfornotidentical,suchasbilletandslabmillrollwithgoodtorsionalandbendingstrength,toughness,bite,thermalcrackingresistanceandthermalshockresistanceandabrasionresistance;tropicalfinishingstandrequirementstherollersurfacehardness,wearresistance,spallingresistance,indentationresistanceandthermalcrackingperformance.什么是铸造轧辊，铸造轧辊主要有哪些种类？铸造轧辊是指将冶炼钢水或熔炼铁水直接浇注成型这一生产方式制造的轧辊种类。铸造轧辊按材质又可分为铸钢轧辊和铸铁轧辊两类；按制造方法又可分为整体铸造轧辊和复合铸造轧辊两类。Whatarethecastingrollsandwhatarethemaintypesofcastingrolls?Thecastingrollerreferstothetypeofrollsproducedbydirectcastingofmoltensteelormolteniron.Thecastingrollcanbedividedintotwotypes:caststeelrollandcastironrollaccordingtomaterialquality.Accordingtothemanufacturingmethod,itcanalsobedividedintotwotypes:integralcastingrollandcompoundcastingroll.)
