摘　　要：利用扫描电镜、X射线和金相法详细研究了9种热轧用高速钢轧辊的相组成和显微结构,分析了成分变化和热处理工艺对显微结构和显微硬度的影响,确定1 050℃～1 150℃为最佳淬火温度、560℃最佳回火温度.确定含量V, C, W, Cr的份数分别为6%~7%、2.06%～2.31%、10.5%~14.4%、4%～6%为最佳成分配比.Phase composition and microstructure in nine high-speed-steel rolls used in hot rolling are investigated in detail by means of scanning electron microscope,X-ray diffraction and metallography. The effects of composition variety and heat treatment on microstructure and hardness are analyzed. Reasonable heat treatment technics and composition ratio are acquired.1 050~1 150℃ are determined as optimal quenching and 560℃tempering temperature, determine components of C, V, W, Cr respective as 6%~7%, 2.06%~2.31%, 10.5%~14.5%, 4%~6% .
