The electric arc furnace is mainly composed of electrode holder, electrode, furnace cover, molten bath, furnace door, tilting cradle, hydraulic steel and other components. The furnace bottom and furnace wall are constructed of acidic or alkaline refractory materials. First, the electric energy is transmitted to the furnace through the electrode, and then the electrode and furnace charge are used to generate electric arc to raise the temperature in the furnace. Finally, the high temperature makes the ore metal melt.
READ MOREThe electric arc furnace automation control system mainly includes three aspects: the electric arc furnace body system, the Consteel horizontal feeding system, and the furnace door furnace wall oxygen lance system.
READ MOREA tapping box protruding from the furnace shell is installed on the original tapping side to replace the original tapping groove. Refractory materials are built inside the tapping box, and a small molten pool is formed. It is connected with the large molten pool at the bottom of the original furnace and has a smooth transition. The tapping hole is opened vertically at the bottom of the small molten pool of the tapping box.
READ MOREThe new furnace body usually needs to be dried to make the furnace body sinter and remove moisture. The alkaline electric arc furnace image is composed of magnesia, dolomite, asphalt, tar and other materials. After the volatiles in the asphalt and tar are removed at high temperature, the remaining solid carbon becomes the skeleton of the furnace lining refractory.
READ MOREFocusing on the objectives of high production efficiency, simple function, environmental friendliness, intelligent control and diversified raw materials, electric furnace steelmaking technology has been continuously developed. The goal of high efficiency of electric furnace smelting is to shorten the smelting cycle and power on time as much as possible and reduce the smelting power consumption as much as possible.
