摘　　要：介绍了矿用电力机车空压机缸套离心铸造的工艺方法;通过调整缸套的化学成分,设计金属型尺寸,确定转型速度,预热金属型,喷涂涂料以及控制冶炼、浇注及铸件出型参数等措施,消除了白口和反白口缺陷,铸件合格率达到95%。The centrifugal casting process of cylinder liner of air compressor used for mine electric locomotive was introduced. By adjusting chemical composition, proper designing dimensions of the permanent mold, adopting reasonable rotation speed of the mold, preheating and coating the mold, as well as controlling parameters of melting process, pouring process and process of taking casting out mold, the chill and reverse chill defects have been eliminated. As a result, the pass rate of castings reached 95%.
