摘　　要：为了提高铁模覆砂生产曲轴的合格率，在保证熔化、覆模、浇注关键环节的前提下，通过大精试验，研究了箱后铸件冷却方式以及开箱时间（温度）对曲轴性能的影响。最终得出了曲轴浇注后11～14min（680-710℃）肝箱，开箱后风机强制冷却的生产工艺。这使QT800—2球铁曲轴铸件达到所要求的性能，能为企业创造良好的经济效益．In order to improve qualified rate of the crankshaft casting with the sand faced-iron mould, on the premise of ensuring key links-melting, laminating and pouring, through a lot of experiments, influences of casting cooling way after unpacking and unpacking time （temperature） on properties of the crankshaft were researched. Finally, production technology that is 11-14 minutes （680-710℃） unpacking after pouring and then forced wind cooling was concluded. This make QT800-2 spheroidal graphite cast iron crankshaft meet requirements of its properties, which can create a good economic benefit for the enterprise.
