Carbon Graphite Electrode HP UHP 600 for Electric Arc Furnaces
Description:
Graphite Electrode is mainly usde for steel-making in electric arc furnace, Ore-smelting Electric furnace and electric resistance furnace. Graphite electrode conduct electric current into the furnace. Electric current produces arc in the smelting
district in the electric furnace, when the temperature increase to about 2000 degree centigrade, raw material begin smelting and products manufactured.A series of graphite electrode is applicable to the common furnace and high power furnace with high pressure and short arc.
Using coal pitch as binder, the graphite electrode which is mainly made of petroleum coke and needle coke is being made through the process of calcination, compounding, kneading, pressing, baking,impregnation, graphitization and machining. It is a conductor that release electrical energy to heat and melt the charge in the form of an electric arc in an electric arc furnace, and has the characteristics of low electrical resistivity, good electrical conductivity, low ash content, uniform structure, good oxidation resistance and high mechanical strength.
Our graphite electrodes has the following feature:
1. Lower electric resistivity, good electric and heat conductivity;
2. High mechanical strength under high temperature;
3. High resistance to thermal shock and mechanical vibration;
4. Lower ash content;
5. According to the customer's feedback information, our electrodes used in EAF/LF with the pretty lower consumption per ton steel.
Graphite electrode, mainly from the domestic petroleum coke and imported needle coke, is widely used in electric arc furnace,ladle furnace, submerged arc electric furnace for theproduction of alloy steel, metal and nonmetallic materials.
