Carbon Additive for Steelmaking
In the smelting process of steel products, it is often because of the long time of smelting, heat preservation, overheating, etc, the melting loss of carbon element in molten iron increases, the decrease of the carbon content in molten iron results in that the carbon content does not reach the expected theoretical value of refining.
Carbon Additive 90% Graphite Pillar/Granule for Steelmaking
GUOXIANG metallurgy production and sales steel making carbon additive such as graphite pillar, graphite granule, graphitized recarburizer etc. Graphite and other impurity materials can be used as carburizer in steelmaking industry. In the smelting process of steel products, it is often because of the long time of smelting, heat preservation, overheating, etc, the melting loss of carbon element in molten iron increases, the decrease of the carbon content in molten iron results in that the carbon content does not reach the expected theoretical value of refining. Graphite and other impurity materials can be used as carburizer in steelmaking industry. Carburizing uses a wide range of carbonaceous materials, including artificial graphite, petroleum coke, metallurgical coke and natural graphite.Stone-lift is still one of the main uses of soil-like graphite in the world.

Application:
Graphite is widely used as electrode in the electrical industry, carbon brush, rods, tubes, mercury rectifier of the anode, graphite gaskets, phone, TV picture tube coating and so on. When smelting all kinds of alloy steel and ferroalloy, graphite electrode is used. At this time, a strong current is introduced through the electrode into the melting area of the electric furnace, generating electric arc and converting electric energy into heat energy. The temperature rises to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, in the electrolysis of magnesium, aluminum and sodium, the anode of the electrolysis cell also USES graphite electrode.The resistance furnace for producing emery also USES graphite electrode as the burner.
