Product Details
Special Alumina Bricks are made by high grade of sillimanite,andalusite,mullite, corundum as raw material, It can resist corrosion of molten and corrosion of industrial slag. with high refractoriness, low creep and mechanical behavior under high temperature, high refractoriness under the load,good thermal shock resistance and slag resistance.
Features Of Special Alumina Brick
Good performance in high temp refractoriness under load
Higher temperate resistant with good refractoriness
Lower impurity content
Good thermal shock resistance performance
Excellent resistance in slag abrasion
Good cold crush strength
