Prediction and Control of Molten Steel Temperature in LF Refining

Ladle furnace refining molten steel temperature prediction and control are the steelmaking process optimization of the main content. Not only does it affect the ability to provide the qualified temperature for the continuous casting of molten steel, whether can achieve the tempo adjustment and multi-furnace continuous casting, but also greatly affect the entire steelmaking process, the on-site operation of energy-saving. Based on the research of the process of ladle furnace refining molten steel temperature prediction and control, we establish the mathematical model of ladle furnace's target heating period temperature; provide the efficiency of formula of ladle furnace and the method to determine the energy; combine the power supply system and temperature control of molten steel together, summarize the principle of ladle furnace refining power. The research and experiment results can help further strengthen the ladle furnace refining process to increase the ladle furnace on the electric stove-ability to regulate the rhythm of casting processes to achieve more energy-efficient furnace and continuous casting.
