Industrial Furnaces SK40 High Alumina Bricks with 80% Alumina Content and 0.1% SiC

China refractory brick manufacturer factory price 80% alumina content SK40 high alumina bricks for industrial furnaces

SK40 High alumina refractory brick, that is, alumina content in 80% or more of an aluminum silicate refractory. Made of bauxite or other raw materials of higher alumina content after molding and calcining. High thermal stability, refractoriness above 1770℃. Good slag resistance.

 Usually divided into three categories:

Ⅰ: Al2O3 content of 75% or more;

Ⅱ: Al2O3 content is 60% ~ 75%;

Ⅲ: Al2O3 content is 48% ~ 60%;

The fireproof degree of high alumina brick is higher than that of clay brick and semisilicite brick, up to 1750~1790℃, which belongs to senior refractory material.

Because Al2O3 is high in high aluminum products, less hybrid mass and less vitreous, the softening temperature of load is higher than that of clay bricks. However, the softening temperature of load is still lower than that of silicon bricks due to the lack of mesh structure formed by mullite crystallization.

There are more Al2O3 in the high alumina brick, which is close to the neutral refractory material and can resist the corrosion of acid slag and alkaline slag. Due to the SiO2 contained in the brick, the ability of alkali slag is weaker than acid slag.
