Water-Cooled Copper Electrode Drum for Slag Door of Electric Arc Furnace (EAF)

Copper drums are an excellent alternative to the existing graphite electrodes for the slag door, installed in the same position as the graphite electrode. Because of the cooling system, these types of equipment have a useful life of 3 to 5 years and significantly reduce the cost of replacement and shutdown of the furnace. Because of the increase in the price of graphite electrodes, the use of copper electrodes is economically justified. On average, in steel complex, due to the quality and fluidity of the produced slag, graphite electrodes last about 100 melts. Besides the high cost of using graphite electrodes, it imposes more costs on the steelmaker for furnace stops. The solution to this problem is to use water-cooled copper electrodes with a life of over 20,000 melts, which is very cost-effective.
