The tapping groove is connected to the furnace shell, and its masonry methods include ramming, pouring, bricklaying or comprehensive masonry.
READ MOREIn recent years, the annual output of crude steel in the world has ranged from 1.6 billion tons to 1.8 billion tons, including more than 400 million tons of electric furnace steel, accounting for about 25%. Except for China, the proportion of EAF steel in the global iron and steel industry has reached more than 40%. The proportion of electric furnace steel in the United States has reached 67%, which is the highest proportion of electric furnace steel in developed countries.
READ MOREElectric arc furnace is an electric furnace for smelting metal and ore at high temperature generated by electrode arc. When gas discharge forms arc, the energy is very concentrated, and the temperature of arc area is above 3000 ℃. For smelting metal, the electric arc furnace has greater process flexibility than other steelmaking furnaces, can effectively remove impurities such as sulfur and phosphorus, the furnace temperature is easy to control, and the equipment covers a small area, which is suitable for smelting high-quality alloy steel.
READ MOREAn electric arc furnace is an electric furnace that uses the high temperature generated by an electrode arc to smelt ores and metals, so it is also called an electric furnace. When the gas discharge in the electric furnace forms an arc, the energy is very concentrated, and the arc zone temperature is above 3000 ℃.

READ MOREAn arc is an arc discharge of a gas. Gas arc discharge is characterized by low voltage between electrodes, large current through the gas, bright white light, high arc temperature (about 5000K). The huge current density comes from the hot electron emission of the cathode and the self-emission of th
READ MOREElectric arc furnaces are large in size and high equipment investment, so only enterprises with a certain scale use electric arc furnaces. Compared with the electric arc furnace, the intermediate frequency induction furnace has a lower cost and is suitable for small and medium-sized enterprises.
READ MOREArc is a kind of arc discharge of gas. Gas arc discharge shows that the voltage between the electrodes is very low, but the current through the gas is very large, there is dazzling white light, and the arc zone temperature is very high (about 5000k). The huge current density comes from the thermioni
