摘　　要：本文对采用泡沫陶瓷过滤器的浇注系统过滤机制进行了分析 ,并确定了过滤效率的方程式。对泡沫陶瓷过滤器过滤液态铸造合金的净化效果进行了验证 ,同时也论述了泡沫陶瓷过滤器在浇注系统中克服阻力的工艺方法。In this paper, we have given an analysis for the filtration mechanism of mould system used cellular ceramic filters, and made certain the equation for filtration efficiency. At the same time, we have validated the refining effect about filtering molten metals by cellular ceramic filters and discussed the technique which overcome the resistance of mould system used the filters.
