Graphite electrode for sale, the product has good chemical stability. The specially processed graphite has the characteristics of corrosion resistance, good thermal conductivity and low permeability. big it is used to make heat exchangers, reaction tanks, condensers, combustion towers, absorption towers, coolers, heaters, filters and pumps. Widely used in petrochemical industry, hydrometallurgy, acid and alkali production, synthetic fiber, papermaking and other industrial sectors, can save a lot of metal materials.
According to its quality index, the graphite electrode can be divided into ordinary power, high power and ultra high power. This series of graphite electrode product has good processability, can achieve complex geometric modeling, light weight, less than 1/4 of the density of copper, the electrode is easy to clamp, good thermal stability, no deformation and no processing burr.
The graphite electrode can also be used for casting, sand turning, die pressing and high temperature metallurgy materials. Because the graphite has a small thermal expansion coefficient and can withstand the change of rapid cooling and rapid heating, it can be used as a mold of glassware, after using graphite, the black metal can be used without processing or a little processing, thus saving a lot of metal. Production of hard alloy powder metallurgy process, usually made of graphite materials die and sintering porcelain boat. The crystal growth crucible, area refining container, bracket fixture, induction heater and so on of single crystal silicon are all processed with high purity graphite. In addition, graphite can also be used as vacuum smelting graphite insulation plate and base, high temperature resistance furnace tube, rod, plate, lattice shed and other components.
Graphite electrodes are sold in a wide range and can also be used in the nuclear and defence industries. Because graphite has a good neutron moderator used in atomic reactors, uranium graphite reactor is one of the more widely used nuclear reactors. As a decelerating material in power nuclear reactor, it should have high melting point, stability and corrosion resistance, graphite can fully meet the above requirements. As the atomic reactor used for graphite purity requirements are very high, the impurity content should not exceed dozens of PPM. In particular, the content of boron should be less than 0.5PPM. Graphite is also used in the defense industry to make nozzles for solid-fuel rockets, nose cones for missiles, parts for space flight equipment, heat insulation and radiation- proof materials.
The allowable current density of conventional power graphite electrode is less than 17A/cm2. The quality of graphite electrode determines the productivity and cost of eaf steelmaking. As manufacturers, we also offer UHP grade graphite electrodes and HP grade graphite electrodes for ultra high power or high power arc furnaces. In addition to electric arc furnace, graphite electrode is also widely used in buried arc furnace and ladle furnace. Welcome customers to consult and purchase, we will provide you with the most appropriate program.
