摘　　要：通过提高轧辊的Cr含量、采用Re-Ti-N复合变质剂处理技术、优化VC和Mo2C碳化物的形态、分布和数量等技术,生产的高速钢轧辊兼具高铬钢的抗热裂性和高速钢的耐磨性能,在棒材K3切分机中替代常用的贝氏体球铁轧辊,取得了良好效果。By increasing the Cr content of the roll,using the Re-Ti-N composite modifier treatment technology,and optimizing the morphology,distribution and quantity of VC and Mo2C carbides,the high-speed steel roll produced has both the hot crack resistance of high-chromium steels and the wear resistance of high-speed steel,which replaces of the commonly used bainitic ductile iron roll in the bar K3 slitting machine with good effect.
