摘　　要：ADI凸轮轴良好的耐磨性、强度受到铸造领域中人们的重视。为了更好地满足等温淬火球墨铸铁件生产工艺要求,以及形成从生产优质球铁凸轮轴到等温淬火的整个过程的成套技术,分别应用喂线法与冲入法生产优质球墨铸铁凸轮轴。对比结果表明:用喂线法生产的球铁凸轮轴球化率、石墨球的圆整度及大小和数量都优于冲入法,结果稳定,铸件亦有很好的力学性能。并在相同等温淬火工艺和等温淬火设备下,等温淬火以后喂线法试样的力学性能优于与冲入法。The ADI camshaft has good abrasion resistance and fatigue strength. In order to better meet the requirements of isothermal quenching nodular iron castings production process, the high quality ductile iron camshaft is produced by wire injection process and pour-over process separately. Comparative results show that wire injection process is superior in spheroidizing, spherical degree, size and quantity of nodular graphite than pour-over process.And the results are stable, the castings have a better mechanical properties. With the same isothermal quenching process and equipment, the ductile iron will obtain better mechanical properties in wire injection process than pour-over process.
