ProductsData sheetsBricks shape


  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.
