Slag Erosion Resistant Metallurgical High Alumina Brick

Slag Erosion Resistant Metallurgical High Alumina Brick – Graded Calcined Bauxite Sintered Shaped Refractory Block With Over 48% Al₂O₃ Matrix, Multi-Grade LZ Series High Strength Thermal Shock Resistant Firebrick For Metallurgical Furnace Slag Contact Working Lining 1. Product Core Profile This metallurgical anti-slag high alumina brick is sintered molded rigid refractory block, forming an independent heavy-duty working lining product category different from lightweight porous Insulating Fire Brick, decorative solid Ceramic Brick, flexible fiber thermal insulation materials and amorphous monolithic castables. The production adopts graded calcined bauxite clinker as main aggregate, matched with fine alumina powder mineral blending, after high-pressure mold compaction and ultra-high temperature tunnel kiln integral sintering to form dense solid brick body with continuous mullite crystal interlocking skeleton. The internal alumina mass fraction is controlled above 48% to form stable aci…
