The production of ceramic foundry sand takes high-quality bauxite as raw material, after calcination, arc furnacnelting and high-pressure gas injection to obtain spherical or nearly spherical sand particles with smooth surfacand then through screening, magnetic separation cleaning, mix matching and other processes, it beomes a multi-functionaicteristics of high fire resistance,stability and strong collapsibility. lt can be recycled and reused, green and covhile the producthave plenty applications in refractory and polishing industries, such as ladle drainage sand, oil sand, hot lighcleaning of aluminum parts, etc.
Ceramic sand is suitable for all kinds of casting process, which as significant advantages in precision casting with high materients and complexcasting, sodium silicate sand casting, self hardening sand casting, hbox casting, cold box casting, investment casting, alloy surfand production of coated sand, refractory coating, drainage sand arother fields。
