Application of Graphite Electrode UHP

Ultra-high-power graphite electrodes (EHSP-UHP) are manufactured for operation at currents with a density of more than 25A / cm2, and the graphite electrode UHP is mainly used for for ultra-high-power arc furnaces and powerful ladle furnaces.

(1) Used in Electric Arc Furnace
Electric furnace steelmaking mill is the largest user of graphite electrodes. Graphite electrodes used in steelmaking accounts for 70%-80% of the total graphite electrodes production. Graphite electrodes are used to conduct electric current into electric furnace, electric arcs generated between electrodes end and loaded materials can release large amount of heat for high temperature smelting.

(2) Used in Mine Electric Furnace
The ore electric furnace is mainly used for the production of industrial silicon and yellow phosphorus. It features in that the lower part of the conductive electrode is buried in the charge, electric arcs are generated in material layer, and the heat released in the charge is used for the smelting. Mine electric furnaces which require high electric current density need to use graphite electrodes. For example, about 100 kg of graphite electrode is consumed for every t of silicon yield, and about 40 kg of graphite electrode is consumed for each t of yellow phosphorus production.

The main raw material of graphite electrode is petrol coke, in regular power graphite electrode, a little amount of pitch coke can be added into the raw material. Both petrol coke and pitch coke should contain no more than 0.5% of sulfur. During producing HP graphite electrode and UHP graphite electrode, needle shape coke should be added into raw material. Petrol coke is the main material for the production of aluminum industry graphite anode, and its sulfur content should not exceed 1.5%~2%.

The Advantages of Graphite Electrode

It is the best electrode material for electric arc furnace steelmaking.
High sublimation point, excellent electric conductivity, high mechanical strength.
Produces CO and CO2 gases when oxidized, won’t contaminate steel.
The density can be adjusted to obtain the best thermal shock resistance.
Low price, easy to process, is the ideal industrial material.

Application of HP Graphite Electrode

The main application of HP graphite electrode is electric furnace steelmaking mill, which consumes about 70~80% of graphite electrode. HP graphite electrode are suitable for EAF furnaces with 18~25A/cm2 current intensity. Meanwhile, HP graphite electrode is also used in ore electric furnaces which are used for making industrial silicon and yellow phosphorous. HP graphite electrodes are also used in resistances such as graphitization furnace for producing graphite products, glass melting furnace and electric furnace for producing silicon carbide.

Application of RP Graphite Electrode

Electric furnace steelmaking mill is the largest user of graphite electrodes. Graphite electrodes used in steelmaking accounts for 70%-80% of the total graphite electrodes production. Graphite electrodes are used to conduct electric current into electric furnace, electric arcs generated between electrodes end and loaded materials can release large amount of heat for high temperature smelting.

(1) For Resistance Furnace
The graphitization furnace for producing graphite products, the furnace for glass melting, and the electric furnace for producing silicon carbide are all electric resistance furnaces. Materials loaded in these furnaces are not only heating resistances but also the objects to be heated. Usually, graphite electrodes for electric conduction are embedded in the wall of resistance furnace end part, so the graphite electrode used here is not continuously consumed.

(2) For the Production of Special Shaped Graphite Products
Graphite electrode workblank is also used to make a variety of special shaped graphite products such as crucible, mold, boat vessel and heating component. For example, in quartz glass industry, for every ton of electrofusion tube, 10t of graphite electrode blank is required, for every ton of quartz bricks, 100 kg of graphite electrode blank is consumed.
