Fire Resistant Mullite Sand With Low Thermal Expansion Coefficient

DM Low FE2O3 Series Mullite Sand of Casting Sand with Stable Physical&Chemical Index Low Thermal Coefficient Expansion

1. Description:

Mullite is a kind of aluminosilicate refractory material.

It is made of hard clay mineral resources by high-temperature roasting, crushing, screening, Raymond, iron removal and other machining processes.

It has high aluminum content, low iron content, small coefficient of thermal expansion, high refractoriness, stable thermochemical properties and other excellent mullite series sands and powders.

2. Application:

Mullite sand of casting sand is widely used in investment casting, gypsum filling V method and vacuum suction casting, as well as large, medium and small steel casting, copper casting, furnace lining refractories, as well as water glass, refractory products, concrete materials, etc.

Widely used in machinery, aviation, weapons, metallurgy, petroleum, heat preservation, sintering, construction and other industries.
