| Al₂O₃ -MgO-CARBON BRICKS | |
| DESCRIPTION: Alumina-magnesia-spinel-carbon brick, resin bonded, tempered, made from fused corundum, bauxite, magnesia 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. | |
