Easy To Peel And Non-Stick Sand Refractory Material Pearl Sand

Product Introduction
Ceramic foundry sand is a kind of artificial refractory material particles, also known as fused ceramsite, ceramsite sand, and jewelry sand . It is made of bauxite as raw material through high-temperature electric melting and granulation processes. It has the characteristics of high strength, high temperature resistance, and low expansion, and is widely used in the casting field.Our company is an enterprise that supplies gemstone sand (jewelry sand, fused ceramsite, ceramsite sand). The product quality is reliable. It is widely used in various casting methods (investment casting, solid mold, lost foam, etc.); it is a new type of raw sand for professional precision casting, coated sand, self-hardening sand, and is also used for shot peening (aluminum, copper, steel castings).

Product Features
Compared with zircon sand, its price is only 30-50% of zircon sand and chromite sand. At the same time, because the sand particles are spherical and have a small surface area, the amount of resin added can be reduced by 30-50%, and the amount of water glass added is ≤4%; it also reduces the casting defects caused by the adhesive and improves the yield rate of castings. It has high refractoriness and is easy to collapse; the mullite phase of the pearl sand is much higher than that of the sintered product, and has good refractoriness; it has high thermal conductivity, good stability, and does not crack.

Application areas ‌
‌Casting process adaptation‌: resin sand, water glass sand, coated sand and V method, lost foam and other casting methods; ‌Metal casting‌: suitable for precision castings of carbon steel, alloy steel (such as high manganese steel), cast iron, cast copper and other materials.

Production process‌
Use high-quality bauxite through calcination, arc furnace melting, spray granulation, screening and other processes to make spherical particles.
