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. Particle Size Chemical Composition Application Max. Application Temperature DQ-960F 5mm >98%SiO₂ Cast iron: lower temperature conditions 1650°C DQ-970F 10mm >98%SiO₂ Cast iron: higher temperature conditions 1700°C DQ-517 10mm >98.5%SiO₂ Gray iron, ductile ironHigher temperature conditions 1650°C DQ-617 5mm >98.5%SiO₂ Gray iron, ductile ironHigher temperature conditions 1650°C DQ-517S 10mm >98.…
