Low voltage and small current must be used to slowly heat up the brine furnace (carbon free furnace lining). If the temperature rises rapidly, the brine will vaporize violently and cause furnace bottom cracking and furnace wall cracking. In the process of furnace drying, it is necessary to arrange an interval to cut off power, check the electrode position of furnace drying, furnace lining sintering, equipment and water cooling system

Electric arc furnaces use electric energy as their main energy source. Electric energy draws arcs through the discharge of graphite electrodes and the charge to generate a high temperature of 2000 ~ 6000 ℃ or more. The scrap steel raw materials are melted by arc radiation, temperature convection and
