low creeping and anti-thermal shock alumina bricks for hot blast furnace
Main materials:andalusite,sillimanite,corundum,mullite stones,flint Property:low impurities,strong thermal shock resistance
Properties of products:
Our high alumina bricks for blast furnaces were mainly made from Bauxite.
Being high pressure pressed and sintered in high temperature.
These products were widely used in all perts of furnace lining .
