摘　　要：高速钢轧辊具有很好的耐磨性、淬透性和高温红硬性,但车削和铣削的难度大,宜采用硬质合金刀具并选择合理的切削参数。在使用中冷却水量应充分并加强维护和保养,确保轧机运行稳定,避免轧槽裂纹扩展。实践证明,使用高速钢轧辊后换辊次数减少,轧辊消耗降低,年经济效益达62万元。但高速钢轧辊使用中存在表面裂纹问题,应从轧辊制造、轧机维护及轧辊保养等方面减少轧辊的非正常报废。High speed steel rolls take on good abradability, hardenability and high-temperature red hardness but are rather difficult to be turned and milled, so hard alloy cutters should be used and rational cutting parameters should be chosen. Cooling water amount shall be sufficient and maintenance should be strengthened in operation to insure the mill moves steadily and prevent the cracks in the groove from expanding. Practice proved that the use of high speed steel roils can decrease the times of roll change and reduce roll consumption, with yearly economic returns up to 620 000 Yuan. However, surface cracks exist in high speed steel rolls when in use, abnormal rejects of roils should be lessened in aspects such as the manufacture of rolls, maintenance of mills and rolls.
