Steelmaking Refractories(TUNDISH)
lt's made from high quality magnesia as main material, mixing with various kinds of additives and binders. Proper size distribution makes it has good workability,easy gunning, non collapse,non-cracking,good corrosion resistance ,longer service life,and easy to disintegrate without sticking.MgO—CaO gunning mix could improve the purity of the molten steel.
