高温合金冶炼过程中泡沫陶瓷过滤器的作用

Role of Ceramic Foam Filter during the Smelting of Superalloy

使用X射线衍射仪、MAAS自动图像仪及气体分析，对1#（美国HITEC公司产）过滤器与2#（昌平产ZrO2基泡沫）过滤器在高温合金冶炼过程中的过滤效果及其组织结构变化进行对比分析．研究结果表明，2种过滤器对钢中氧化物夹杂均有显著去除效果，并且过滤器的组织结构会对其高温性能、冲击性能及过滤作用产生一定的影响．

The influence of different filters on efficiency of filtration and microstructures during the superalloys melting was investigated by means of X-ray diffractor , MAAS automatic image instrument and gas analyse. The experimental results show that both filters can strongly remove oxides, and that filter microstructures effect on the high-temperature property, impact property and efficiency of filtration of the filters.
