将W18Cr4V高速钢废料，采用中频感应炉熔炼，出钢前加Al，熔模精密铸造车刀刀具，经淬火和四次回火后，硬度达HRC64．5，冲击韧性达到22．1J／cm2．精铸车刀寿命与锻造的相当。
The W18Cr4V high-speed steel scrap, the use of intermediate frequency induction furnace melting, tapping before Al, investment precision casting tool turning tools, after quenching and tempering four times, the hardness of HRC64.5, the impact toughness of 22.1J / cm2. Casting tool life and forging quite.
