【Abstract】 It is available to improve the morphology and distribution of eutectic carbide in high speed steel (HSS), obviously increase the impact toughness of HSS by adjusted chemical compositions and inoculated casting with RE\|Mg\|Ti treated agent. The strength\|toughness and wear resistance of inoculating HSS rolling mill guides are appreciably better than that of ordinary guides. The HSS guide service life increased by more than 2 times as compared with that of ordinary guides.更多还原
