Refractories for Iron Melting

Refractories for Iron Melting Characteristics of Acid Dry Ramming MixAcid dry ramming mix made from high-purity natural quartz sand and fused quartz sand as the main raw materials, designed with a special particle size distribution. An appropriate amount of sintering agent is added to form a well-sintered layer with good strength at high temperatures, while retaining a sufficient loose layer.Suitable for intermittent production of various metals such as gray iron, ductile iron, high-chromium cast iron, high phosphorus pig iron, carbon steel, etc. Product Name Max.
