SEPPE Bauxite Sand Used for Foundry and Casting:
1. Artificial bauxite sand has small thermal expansion coefficient, good performance as zircon sand;
2. Spherical appearance with good liquidity and better ventilation;
3. Smooth surface with compact structure, uniformly covered of adhesive;
4. It is a neutral materials that can be used with acids, bases or binders;
5. Can be recycled, cost-effective;
6. Price is only 25-50% of chromite sand and zircon sand. Meanwhile, sand is spherical with small surface area, so the added amount of the resin can be reduced by 30-50% and the added amount of sodium silicate ≤4%; and reducing casting defects caused by the binder and improving the output of castings;
7. High refractoriness, easy collapsing;
8. The fire resistance of mullite in the bauxite sand is much better than other sintered products;
9. Good thermal conductivity and stability without cracks;
10. Wide applications. Used for polishing and cleaning of resin sand, sodium silicate sand, clay sand, EPC, investment casting, copper and aluminum.
SEPPE Bauxite Sand Features & advantages
1. Lower thermal expansion rate and thermal conductivity: It is just this characteristic that makes the
foundry more precisely, less cracking and high output. Improve foundry quality.
2. Lower cleavage breakage rate: It has high density and has very low cleavage breakage rate. Easily
reclaimed that makes it more protect environment for the less sand powder occurred.
3. High refractoriness and service temperature: Major element is Al2O3 that has very good refractoriness.
