Refractory Bricks Manufacturer

The Technical Development of EAF Steelmaking   has a history of about 100 years. Although always facing the challenges and competition of several other steelmaking methods, especially the impact of high-efficiency oxygen converter steelmaking, the proportion of steel production in electric arc furnace steel production in the world's total steel output continues to rise year by year. Electric arc furnace steelmaking relies on graphite electrodes to generate electric arc, which converts electric energy into thermal energy in the arc light. Steelmaking method of melting furnace charge and removing impurity components such as sulfur and phosphorus, and then adding required elements (such as carbon, nickel, manganese, etc.) to smelt various steels or alloys with different properties. Furnace temperature can be accurately controlled with electric energy heating, which produces less high-temperature exhaust gas, and the thermal efficiency of electric arc steelmaking fur...

Graphite electrodes are mainly divided into ordinary power graphite electrodes, high power graphite electrodes, impregnated graphite electrodes, high bulk graphite electrodes, and ultra high power graphite electrodes. Due to its thermal and electrical properties, it is widely used in various industries. The main uses of graphite electrodes are as follows.   Uses of Graphite Electrodes First, for electric arc steelmaking furnace Graphite electrodes are mainly used in electric furnace steelmaking. Electric furnace steelmaking uses graphite electrodes to introduce current into the furnace. A strong current generates an arc discharge through the gas at the lower end of the electrode, and uses the heat generated by the arc to perform smelting. According to the capacity of the electric furnace, graphite electrodes with different diameters are used. In order to make the electrodes continuously used, the electrodes are connected by electrode screw joints. Graphite electrod...
