Mullite sand is silicate aluminum refractory material, generally used in stainless steel
precision casting process. The characteristics are small expansion coefficient, high hardness,
Strong resistance to chemical corrosion,high refractoriness, good thermal and chemical
stability,resistance to extremely cold / heat, etc., while product molding shell and pouring
castings it's easy shelling,no deformation,not reduce scale,good finish, high yield.The
product can be used for complex casting of carbon steel, stainless steel, heat-resistant steel.
1.Grain shape of the foundry sand is close to the true round with smooth surface,
good fluidity and fillibility, easy to be filled ,it can get good formability and strength of
mold.
2.Foundry sand has a good collapsibility, easy to carry out the sand cleaning operation.
The usage amount of binder is more less than other types of sand.
3.Compounding moulding sand with foundry sand, casting will not have defects of
expansion cause it has low thermal expansion rate.
4.Producing castings with foundry sand will have high accuracy ,less fracture and
surface defects, what's more it can also improve the yield of casting.
5.Foundry sand has good crushing resistance and high strength, it's rarely broken
even if reuse.
6.The foundry sand with good reproducibility can reduce dust pollution in the
production process and industrial waste emissions,is conducive to environmental
protection.
7.Foundry sand has a good fire resistance,refractoriness ≥1790 ºC which makes it can cast various metals and alloys.

Jingang New Materials Co., Ltd is a provincial high-tech enterprise mainly in R&D, producing and marketing high-purity ultrafine alpha alumina powder, micrite wear-resistant alumina ball, alumina lining brick and special specifications of alumina ceramic products etc. The products can be widely used in building ceramic and sanitary-ware ceramic industry, steel, cement chemical, thermal power plant and other industries. It owns nine high temperature tunnel kilns, three rotary kilns and other corollary equipments with annual output of 80, 000 tons of high alumina products and 150.000 tons of alumina powder. In 2011, Jingang has become one of the first batch of 100 strategic emerging industries enterprises announced by Shandong provincial government and it successfully held the national industrial ceramic standardization committee annual meeting, as a result, It was elected as director unit, and obtained the discursive power in its industry. The company established the sole provincial engineering technology research center in the special ceramic industry therefore Jin Gang has become the first in domestic alumina industry in scale, output and technological innovation.
