China refractory manufacturer factory supply 70 high alumina brick for heating furnace
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%;
Ⅲ: Al2O3 content is 48% ~ 60%;
