Magnesium, magnesium calcium dry ramming material/refractory castable/clean steel, good thermal insulation effect
Product description:
This series of products is made of high-quality magnesite, fused magnesia, dolomite and other raw materials plus non-liquid binder. In addition to special steel grades, it has been widely used in continuous casting tundish of steel mills at home and abroad, and has gradually replaced the water-filled tundish coated products with long service life, clean steel, good thermal insulation effect, and easy disintegration of residual lining.
