Product Introduction
Baozhu sand is an artificial spherical refractory material made of high-quality bauxite through arc furnace smelting, granulation and other processes. Its core characteristics include: excellent physical properties: spherical particles (close to a perfect circle) bring excellent fluidity and air permeability, bulk density 1.95-2.05g/cm³, thermal expansion coefficient as low as 6×10-6/ºC (20-1000ºC), refractory temperature ≥1790ºC.
Product Advantages
Can significantly reduce the expansion defects of castings; Environmental protection and safety: no silica dust hazards, no toxic substances released during production and use, in line with green casting requirements; strong process adaptability: suitable for a variety of bonding systems such as resin sand, water glass sand, coated sand, compatible with lost foam, V method, investment casting processes, etc., widely used in precision molding of metal castings such as carbon steel, alloy steel, and cast iron.
Our advantages
This product is made of high-quality aluminum ore raw materials through high-temperature calcination, electric melting, and high-pressure aerosol spraying. It has a much better cost-effectiveness than zircon sand and chromite sand; in particular, it has low expansion, no sintering, no pulverization, no cracking, no sand adhesion (eliminating the negative impact of casting quality), good regeneration performance, and improves the finished product rate of castings.
