Ceramic Foundry Sand
The casting has been a serious pollution of the environment industry, in order to improve the quality of castings, reduce production costs and improve the environment, a new study of foundry sand – Ceramic Foundry Sand, is imminent. By adding the electric arc furnace containing Al2O3 45%-90% raw bauxite ore, the high temperature produced by the arc of the arc discharge, the raw material bauxite melted liquid, the liquid flows out of the furnace, impose its 70-85m/s to air pressure, the liquid material with the strong wind crushing, cooled to obtain spherical or nearly spherical shape, smooth sand performance.
