Why must the new electric arc furnace for steelmaking be dried up - part 2

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 furnace's future technical direction

With the goal of "high efficiency, low consumption, green and intelligent", steel enterprises need to select appropriate electric furnace type and production technology. The raw material of converter process is mainly liquid molten iron, the raw material of electric furnace process is mainly solid scrap, and the final product form is liquid steel. The different transformation of physical and chemical forms determines the different control methods.
