Ceramsite sand casting

This ia new sand for alloy steel casting,more environmental protection than quartz sand is a refractory material particle made from high-quality bauxite through processes such as electric melting, high-temperature melting, granulation, and screening.

Advantage:

has small thermal expansion coefficient, good sand mold stability,

no cracking, and reduces Casting defect such as veins caused by sand expansion.

has a particle size close to spherical, a smooth surface, and a dense structure, which enables the binder to evenly cover, has good flowability,

it is easy to compact.has high hardness, is not easily broken, and produces almost no ash. The amount of resin added can be reduced by more than 30%,which can reduce the gas generation of mold/core sand and reduce the risk of pore formation.

The mullite phase of Ceramsite sand is much higher than that of sintered products, with a high fire resistance that exceeds the pouring temperature of molten steel.

 Good recycling and regeneration performance, high durability and regeneration recovery rate, with a regeneration rate of up to 98%

equipped with automatic casting molding line, high produce rate and stability casting quality,
