High Power Graphite Electrode Details
Graphite electrode, mainly using petroleum coke and needle coke as raw materials, coal tar pitch as binding agent, made by calcination, batching, kneading, pressing, roasting, graphitization, and machining. It is released in the form of electric arc in an electric arc furnace. The conductor used for heating and melting the charge by electric energy can be pided into ordinary power, high power and ultra-high power according to its quality index.
Advantage:
1. Processing speed: high-speed milling rough machining is 3 times faster than copper; high-speed milling finishing is 5 times faster than copper
2. Good machinability, can realize complex geometric modeling
3. Light weight, density is less than 1/4 of copper, electrode is easy to clamp
4. The number of single electrodes can be reduced because they can be bundled to make a combined electrode
5. Good thermal stability, no deformation and no processing burrs
Application:
Mainly used in smelting furnaces such as electric arc furnaces and refining furnaces in iron and steel smelters. Electric steelmaking uses graphite electrodes to introduce current into the furnace. The powerful current generates arc discharge through gas at the lower end of the electrode, and uses the heat generated by the arc to smelt. According to the capacity of the electric furnace, graphite electrodes of different diameters are equipped. In order to make the electrodes continue to be used, the electrodes are connected by electrode screw joints. Graphite electrodes for steelmaking account for about 70-80% of the total amount of graphite electrodes.
Semi-silica brick refers to an aluminum-silicon refractory product with a SiO2 content of greater than 65% and an Al2O3 content of 15% to 30%. They generally use clay containing quartz impurities or native kaolin refractory clay or tailings and pyroph...
The Al2O3 content of anchor bricks is above 55%, and some users require that the alumina content reach 75%, and the load softening temperature of 75% bricks reaches 1550C. However, in actual use, anchor bricks with high aluminum content cannot be enough. The key is Flexibility is the most important t...
