        Al?O? -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.
