DH-MAC55/30-10B


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.
