Neutral Dry Furnace Lining for Tundish Coating Refractory Material. Neutral Dry Furnace Lining for Tundish Coating is a wet pasty refractory material mainly made of magnesia and high-alumina raw materials with special binders added. HN series tundish coatings are characterized by easy application, crack resistance, excellent erosion resistance, long service life and easy dismantling. Compared with insulating boards, they can reduce non-metallic inclusions in molten steel, improve steel cleanliness and steel properties, cut costs and raise economic benefits. Model HN-ZBTM4 tundish coating is specially developed for steel grades with strict phosphorus content requirements such as stainless steel. it prevents phosphorus contamination of molten steel inside the tundish.
