Description:
Graphite electrode, mainly petroleum coke, needle coke as raw material, coal pitch as binder, calcination, ingredients, kneading,molding, baking and graphitization, machining and made, which is released in electric arc furnace in the form of arc conductor of electricity to heat melting furnace charge, with low resistivity, good conductivity, low ash, uniform and compact structure, good oxidation resistance, high mechanical strength, etc.
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.
