High-temperature ceramic materials for precision casting

　　Precision casting is a general term for processes that produce castings with precise dimensions. Compared to traditional sand casting, precision casting produces castings with more precise dimensions and better surface finish. It includes: investment casting, ceramic mold casting, metal mold casting, pressure casting, lost-foam casting, etc. The ceramic materials involved in precision casting mainly include: ceramic filters, ceramic crucibles, ceramic pouring cups, etc.

　　Molten Stone Foam Ceramic Filter

　　Ceramic filters are mainly used for metal casting filtration in the foundry industry. Suitable for cast steel and large cast iron parts, they effectively remove large inclusions from the molten metal, adsorb small particulate impurities, and improve the mechanical properties of the castings. Applicable to all steel grades, including carbon steel, stainless steel, cobalt-based, and nickel-based high-temperature alloy steels.

　　Foam ceramic filters are used to filter out solid slags such as metal oxides contained in molten metal during precision casting, thereby improving the quality and yield of castings. Therefore, the use of foam ceramic filters has promoted technological advancements in the foundry industry.
