Product Introduction
Series of magnesia and magnesia-calcium coatings for tundish are mainly made of high-quality magnesia and magnesia-calcium sand. It is suitable for spraying or smearing, with high service life, strong disintegration, easy to dismantle, which is conducive to purifying molten steel and reducing the pollution of refractory materials to molten steel. It is the choice of lining material for pouring special steel and high purity steel.
