综述了常用的网型、芯型、泡沫陶瓷过滤器的研究和应用情况。指出应根据过滤器类型，确定其在浇注系统中的安放位置并相应改变该处的结构和截面积，以便在使用过滤器净化金属的同时，保证充型速度不变。
The research and application of commonly used mesh, core and foam ceramic filters are reviewed. It is pointed out that according to the type of filter, the location of its placement in the pouring system should be determined and the structure and cross-sectional area changed correspondingly so as to ensure the filling speed is unchanged while using the filter to purify the metal.
