A 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 MOREElectric furnace equipment is usually a complete set, including electric furnace body, power equipment (electric furnace transformer, rectifier, frequency converter, etc.), switches, auxiliary auxiliary appliances (resistors, compensation capacitors, etc.), vacuum equipment, detection and control instruments (electrician Instrumentation, thermal instrumentation, etc.)
READ MORETo achieve slag-free tapping of electric furnaces, traditional tapping methods need to be changed. The rapid progress of electric furnace technology is not only reflected in the number of electric furnaces, but also the furnace type and tapping mechanism and control methods are constantly changing and updated, making the electric furnace slag-free tapping technology more perfect and diversified.
READ MOREEBT electric furnace can retain 10% ~ 15% steel and more than 95% slag through eccentric bottom tapping. EBT electric furnace realizes slag free tapping by leaving 10% ~ 15% steel, maintaining sufficient molten steel in the tapping box and rapid back tilting (3 °/s) of the furnace body during tapping and tilting.
READ MOREWhat are the main aspects of electric arc furnace intensified smelting and process energy saving? In recent years, Chinese electric arc furnace steelmaking enterprises have adopted different intensified smelting process technologies and equipment, and have made significant progress in improving production efficiency, reducing smelting power consumption, and recovering secondary energy. Energy-saving technologies of electric arc furnace steelmaking process mainly include:
READ MOREElectric arc furnace uses the high temperature generated by the electrode arc to smelt ores and metals. When the gas discharge forms an arc, the energy is very concentrated, and the arc zone temperature is above 3000 ℃. For smelting metals, electric arc furnaces are more flexible than other steelmak
