MgO-Al₂O₃-CARBON BRICKS | |
DESCRIPTION: Magnesia-Alumina-carbon brick, resin bonded, tempered, made from fused magnesia ,Fusedcorundum, bauxite,and flake graphite. MAIN APPLICATION: Sidewall and Bottom of steel treatment ladles, increased flexibility by spinel formation and therefore reduced slag infiltration and high thermal shock resistance. | |
