Properties of Fluorine-Free Steelmaking Flux Prepared Using Red Mud
MetalsThe basic oxygen steelmaking process is based on the CaO-FeO-SiO2 ternary slag system, characterized by a high melting point and low lime dissolution rate, often becoming one of the key factors limiting the efficiency of the converter.
