Development and Application of Variable Current Electrode Regulator for Ladle Refining Furnace
Ladle furnace(LF)has been widely used in recent years.It is an important refining equipment.In smelting process,It consumes a large amount of electric energy to increase the temperature of molten steel and belong to a process link with high energy consumption.Under the policy background of national advocacy of green intelligent manufacturing and carbon neutralization of carbon peak.It is an urgent problem for metallurgical enterprises to reduction of process power consumption of LF furnace and improve the intelligent level of smelting process.The pa-rameters of electrode regulator are dynamically adjusted by collecting the actual working condition information to reduce the smelting power consumption and the maximum demand power consumption of LF refining furnace and realize green manufacturing.It reduce carbon emission by reducing the loss of graphite electrode.In addition to constant current and constant impedance,the third variable current electrode regulator of LF furnace with independent intellectual property rights was creatively developed.It has been successfully applied to 2 # LF,3 # LF and 4# LF furnaces in the steelmaking plant of Benxi steel plate Co.,Ltd..It has a good prospect of popularization.
