The high-aluminum poly-light insulation brick produced by our company is a kind of brick made of bauxite clinker, high-quality bauxite raw materials and poly-light balls by squeezing to mold and cutting to process after high temperature firing.
The high-aluminum poly-light insulation brick produced by our company is a kind of brick made of bauxite clinker, high-quality bauxite raw materials and poly-light balls by squeezing to mold and cutting to process after high temperature firing. The brick with high strength, low thermal conductivity, good thermal shock resistance, small linear change on reheating and appearance of standard size, can be widely used to construct the thermal insulation layer and the lining of the furnaces in steel, nonferrous metals, carbon, ceramics and other industries.
