Product Description

China refractory manufacturer factory supply 70 high alumina brick for heating furnace

Long Service Life 70 High Alumina Brick for Industrial Furnaces International Standard

70 High alumina brick, that is, alumina content in 48% 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.

70 High alumina bricks can be classified according to its mineral composition, generally divided into five categories: low Mullite (silystone), Mullite, Mullite-corundum corundum - mullite and corundum.

The high alumina lining bricks usually divided into three categories:

Ⅰ: Al2O3 content of 75% or more;

Ⅱ: Al2O3 content is 60% ~ 75%;
