It is mainly made of petroleum coke and needle coke as raw materials, coal tar pitch as binder, and electrode paste through calcination, batching, kneading, molding, roasting, graphitization and machining. It is a conductor that releases electric energy in the form of electric arc in the electric arc furnace to heat and melt the furnace charge. According to the quality and carbon product volume index, it can be divided into ordinary power, high power and ultra-high power.

Graphite electrode includes: ordinary power graphite electrode. Graphite electrodes with current density lower than 17a/ cm2 are allowed to be used, which are mainly used in ordinary power electric furnaces for steelmaking, silicon smelting, yellow phosphorus smelting, etc. It is made from petroleum coke, anthracite and metallurgical coke with coal tar pitch as binder. Some electrode pastes are used as conductive electrodes in various continuous self baking electric furnaces;

Electrode paste self baking carbon block for blast furnace has different uses

Some anode pastes are used for continuous self baking aluminum tanks as conductive anodes; Some are used as filler for blast furnace masonry and coarse and fine joint paste of refractory slurry. Although the self baking carbon block for electrode paste blast furnace has different uses, it is similar to the production process of paste products and is temporarily classified into paste products.

The main raw materials for producing electrodes are anthracite, metallurgical coke and coal and coal tar pitch, which can be divided into two categories according to different formulas: standard and non-standard electrode pastes: standard electrode pastes are mainly used in open ferroalloy furnaces and medium and small calcium carbide furnaces, and medium temperature asphalt is used as binder; Electrode paste non-standard electrode paste is mainly used in large open calcium carbide furnace. Its dry material particle composition is the same as that of standard electrode paste, but in order to appropriately improve the sintering speed of electrode paste
