Ladle refining furnace (Ladle refining furnace) refers to equipment that has both the heating and refining functions of a steelmaking furnace. It is an important metallurgical equipment used for refining molten steel melted in primary furnaces (electric arc furnace, open hearth, converter), and can adjust the temperature of molten steel, process buffering, and meet continuous casting and continuous rolling requirements.
