Silica Refractory Brick For Hot Blsat Stove - China

Advantages:

•CUNSE has its own crystalline silica mine in Tie men Town which is famous for its silica mine.

•High purity, good thermal conductivity, high refractoriness under load and high tridymite content, low true density, low expansion, low creep and low residual quartz content, good dimension and appearance.

Application:

•Widely used in hot blast stoves.

•Used in high temperature sections of the checker chamber in hot blast stoves.

•Used as low-cost alternative to andalusite and mullite checker bricks in hot blast stoves.

•High refractoriness,

average thermal shock resistance makes it suitable in consistent temperature environment.

Technical Index:

•mineralized Sillica content exceeds 95% •Refractoriness up to 1710℃
