graphite electrode of ultra high power
What products are included in graphite electrode of ultra high power products?
Electrode products mainly include graphite electrode of ultra high power for steelmaking furnaces, carbon electrodes and self-baking electrodes for submerged arc furnaces such as smelting yellow phosphorus, ferroalloys and calcium carbide.
The graphite electrode has ordinary power graphite electrode ultra high power and high power and ultra high power graphite electrode. To produce ordinary power graphite electrode of ultra high power, petroleum coke of general quality can be used as raw material. If the strength is generally a small amount of pitch coke should be added to improve the mechanical strength of the electrode. Pitch coke is not used abroad, but asphalt with high softening point is used as a binder. In the production of high-power graphite electrode and ultra-high power graphite electrode, needle coke must be used as the raw material, so that the uhp graphite electrode can be obtained with lower resistivity and lower linear expansion coefficient.
For the raw materials of steel-making electrodes, the content of sulfur and phosphorus should be controlled. Sulfur and phosphorus will cause hot and cold brittleness of steel. Carbon electrodes mainly use anthracite and metallurgical coke as raw materials. Sometimes a small amount of natural graphite or graphitized crushed is added, and sometimes a certain amount of petroleum coke is added.
The natural graphite electrode of ultra high power uses natural graphite as the raw material, and the product does not undergo high temperature graphitization. This kind of electrode has a large electrical resistivity, low mechanical strength, and is easy to break during use. Recycled graphite electrode ultra high power is an electrode produced by crushing scraps or waste graphite electrode processed by graphite electrode of ultra high power. Its electrical resistivity is also large, thermal stability is poor, and raw materials The source is limited, and it is not suitable to produce large-size electrodes. The electrode paste of the self-baking electrode uses anthracite and metallurgical coke as raw materials. In order to reduce the resistivity and improve the sintering performance, artificial graphitized broken or natural graphite can be added.
For high-grade primary and secondary electrode pastes, electrically calcined anthracite (partially graphitized) should be used as the raw material. Taking into account factors such as low-grade products’ raw materials, energy consumption and environmental protection, both electrode paste and anode paste are phased-out products. CGM New Materials Co., Ltd. is a manufacturer of uhp graphite electrode. Its products include graphite electrode of ultra high power (common Power graphite electrode of ultra high power, high power graphite electrode of ultra high power, ultra high power graphite electrode of ultra high power) graphite products, recarburizers, graphite crucibles, graphite plates, etc.!
