Practice of furnace expansion and transformation of 3 t electric arc furnace
ln view of the actual situation of small tonnage and high unit consumption of molten steel smelting in the company's aging 3 t electric arc furnace,the author realized the expansion of the fur-nace chamber and the expansion of the charge by moderately transforming the taphole of the furnace shell.The measures to increase the inclination angle of the tap groove solve the problem of collision between the wire rope of the ladle crane and the electrode frame of the electric arc furnace caused by the improvement of the tap port,and the capacity of the furnace is expanded from the original rated capacity of 3 t to 5 t after the expansion,which significantly improves the efficiency of molten steel smelting,and provides technical support for energy saving,consumption reduction,production increase and efficiency increase for molten steel smelting in the old 3 t electric arc furnace.
