Description

Customizing Refractory Sand for Ceramic Products Making with Low Thermal Expansion

1.What is the refractory sand?

The refractory sand is made of kaolin or mullite by high temperature sintering. The chemical components of mullite are all chemical substances with strong fire resistance, and their properties are relatively stable. It mainly includes: alumina, silica, etc., the content of alumina is between 42% and 46%, and the content of silica is between 51-53%. In addition, there are less substances: iron oxide, sodium superoxide, potassium superoxide, titanium oxide, magnesium oxide, etc.

2.How do we get it ?

The sand is a kind of alumina silicate mullite sand and powder. It is a series of mullite sand and powder with high aluminum content, low iron content, low coefficient of thermal expansion, high refractoriness and stable thermochemical proprities, which are made of hard clay mineral resources through high-temperature roasting, crushing, screening, Raymond, iron removal and other machining processes.

3.Where is it used for?

The products are mainly used in investment casting,especially in reinforcement layer, gypsum filling V method molding and vacuum suction casting, as well as refractories for large, medium and small steel castings, widely used in machinery, aviation, weapons, metallurgy, petroleum and other industries.
