: ceramic foundry sand offers longer work life and reduction of sand usage ceramic foundry Sand’s spherical shape compared with angular shaped grains allows for easier separation from cast parts and improved collapsibility resulting in lower scrap and casting efficiency SAFE – to environment compared with silica (silicosis) Lower thermal expansion and Thermal Conductivity. Casting
Ceramic Foundry sand ,also called as Fused Ceramic Sand is made from high quality bauxite, by re-fused and blown to ball type. With advantage of fine surface smooth finish and air permeability, it is a new type casting material for precision casting, coated sand and self hardening sand etc.At the present, Ceramsite is acknowledged in the
Ceramsite sand is a kind of fused ceramic sand,it is made from calcined bauxite with main content aluminium oxide processed by melting,blowing,sieving and blending. Ceramsite sand Physical and Chemical Composition Chemical Analysis[%] Al2O3 70-75 SiO2 8-20 Fe2O3 ≤3 TiO2 ≤3.5 CaO ≤0.45 MgO ≤0.35 K2O ≤0.33 Na2O ≤0.08 Physical Properties Grain shape Spherical Ball Roundness 90%
How to Choose grit size？ Generally，the smaller casting need to make, the finer grit size foundry adopted.The following frame shows it for reference: Less than 500KGS 500-1000KGS 1-10 Tons 10-30 Tons 30-100 Tons AFS40-70 AFS 45-50 AFS 45-50 AFS40-45 AFS 35-40 Specification CHEMICAL COMPOSITION Cr2O3 ≥46.0% SiO2 ≤1.0% FeO ≤26.5% CaO ≤0.3% MgO ≤10% AL2O3
