Magnesite Alumina Spinle Brick

Description:

Magnesite-alumina spinel brick is a kind of basic refractory material made of magnesia and industrial alumina or bauxite as raw materials, which are crushed and shaped and fired at about 1600 ℃. Its refractoriness is higher than 2000 ℃, thermal shock resistance is better than that of magnesium bricks, and it can resist the corrosion of alkaline slag.

Advantage:

Excellent thermal shock resistance, high refractoriness under load, resistance to alkaline slag erosion

Application:

Cement rotary kiln
