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.

1. Undertake the original partial refining function of primary refining furnace, complete partial steelmaking reaction under the best thermodynamic and kinetic conditions, and improve the production capacity of monomer equipment; 2. Uniform molten steel and accurate control of steel composition; 3. Accurately control the temperature of molten steel to meet the requirements of continuous casting production;

In order to homogenize the composition and temperature, the gas stirring process in the ladle appeared. The most striking is the adoption of secondary refining, which greatly improves the output and quality of steel. However, what is the main task and purpose of secondary refining? The composition of molten steel, decarburization, deslagging and refining of molten steel shall be adjusted according to the target of molten steel, molten steel melting, deslagging and refining.
