        MgO-Al?O?-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.
