700mm UHP Grade Carbon Graphite Electrodes for Arc Furnace

700mm UHP Grade Carbon Graphite Electrodes for Arc Furnace

Description:

Graphite electrodes are a type of conductive material made from high-purity graphite. They possess excellent electrical conductivity and chemical stability.Graphite electrodes are mainly made from petroleum coke and needle coke as raw materials, with coal tar asphalt as the binder. They are produced through processes such as calcination, batching, mixing, molding, baking, graphitization, and machining. They are conductors that are heated and melted by an electric arc in an electric arc furnace to release electrical energy. Depending on their quality indicators, they can be classified as RP graphite electrode, HP graphite electrode, and UHP graphite electrode.

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.
