Electric arc furnace steelmaking uses electric energy as heat energy and uses the high temperature of the arc generated between the electrode and the charge to heat and melt the charge. It is widely used in the production of smelting ordinary steel, high-quality carbon steel, various alloy steel, and stainless steel, and is the key equipment in steel mills and foundries. The electric arc furnace includes a water-cooled furnace wall and water-cooled furnace cover; eccentric bottom tapping; conductive composite cross arm; advanced intelligent electrode lifting regulator, energy saving and consumption reduction; industrial configuration screen monitoring system.
