Graphite electrodes are used mainly in electric arc furnace steel production. They are presently the only products available that have the high levels of electrical conductivity and the capability of sustaining the extremely high levels of heat generated in this demanding environment. Graphite electrodes are also used to refine steel in ladle furnaces and in other smelting processes. HP Graphite electrode has good electrical properties and chemical stability. What’s more, graphite electrode has advantages of high mechanical strength, low impurity content and good vibration resistance. Graphite electrodes are good conductors of heat and electricity. Graphite electrode is widely used in steelmaking electric furnace, refining furnaces, production of ferroalloy, industrial silicon, yellow phosphorus, corundum , submerged arc furnaces and other smelting furnaces that produce high temperatures by electric arc. According to the different of service power and electricity , using different refractory raw materials and production technology, graphite electrodes can be divided into ordinary power graphite electrodes, high power graphite electrode, ultra-high power graphite electrodes. Our graphite electrode is made from the domestic first petroleum coke and high quality needle coke and widely used in the electric furnaces refractories for production of alloy steels, metal and other refractory nonmetallic materials, etc. The HP graphite electrodes include regular power, high power graphite electrode, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to 700mm. Article Source: HP Graphite electrode Company name: Wanhao Refractory Email:sales100@wanhaorefractory.com Website:http://www.wanhaorefractory.com/

HP Graphite Electrode

High power graphite electrodes refer to the graphite electrode that allows the use of a current density of 18 ~ 25A / cm2.
Graphite electrode has good electrical properties and chemical stability. What’s more, graphite electrode has advantages of high mechanical strength, low impurity content and good vibration resistance. Graphite electrodes are good conductors of heat and electricity. Graphite electrode is widely used in steelmaking electric furnace, refining furnaces, production of ferroalloy, industrial silicon, yellow phosphorus, corundum , submerged arc furnaces and other smelting furnaces that produce high temperatures by electric arc.
According to the different of service power and electricity , using different raw materials and production technology, graphite electrodes can be divided into ordinary power (RP) graphite electrodes, HP graphite electrodes, ultra-high power (UHP) graphite electrodes.?

Application:

High power graphite electrode is mainly used in high-power electric furnace and ladle furnace.

HP Graphite Electrode

Moulding powder forms ”three layers”?in the crystallizer, powder layer, sintered layer and slag layer. This working mode is the key to play the role of moulding powder. The casting powder (1100~1200℃ melting point) on the surface of the molten steel (1500℃), heated by the molten steel and forms slag layer with 10-15mm thickness on the surface of molten steel. With the heat transfer slowed down, the moulding powder above slag layer sintered, forms sintered layer (900-600℃). And the casting powder above the sintered layer will gets fewer heat transfer, less than 500℃, so this is the powder layer. And the moulding powder covers in the molten steel surface evenly, to prevent cooling and secondary oxidation of molten steel. During casting, the slag film between crystallizer and solidified slab shell could reduce the casting resistance and improve the heat transfer of crystallizer. As casting going , the slag layer is consumed constantly, then sintered layer becomes slag layer, powder layer becomes sintered layer, and adds more moulding powder into the crystallizer, makes the moulding powder keeps “three layers“.
