mullite fine powder for refractory product

Description

Mullite fine powder is the use of hard clay mineral resources to advanced processing technology, after high temperature roasting, crushing, screening, Raymond, iron and other processes produced; with high aluminum content, low iron, high hardness, thermal expansion Coefficient is small, high refractoriness, thermal chemical stability and so on.
Mullite fine powder is mainly used for melt casting, gypsum filler V method modeling and vacuum casting molding materials, and large, medium and small cast steel, cast copper, lining refractory materials, but also for the manufacture of water glass, refractory products , Concrete materials, widely used in machinery, aviation, weapons, metallurgy, oil, insulation, sintering, construction and other industries.
