Q:What about graphite electrodes for steel mills?
Hebei North graphite electrode factory produces various specifications of graphite electrode, with low resistance, high density, small ash, and so on, so that less tons of steel-making, quality is good
Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
Petroleum coke is divided into needle coke and sponge coke and projectile reef, fixed carbon content components of petroleum coke is around 80%
Q:Synthesis techniques of carbon nanotubes
Laser evaporation is an effective method for the preparation of single-walled carbon nanotubes. Single walled carbon nanotubes and single-walled carbon nanotube bundles were prepared by evaporation of carbon targets doped with Fe, Co, Ni or their alloy by high energy CO2 laser or Nd/YAG laser. The diameter of the tubes can be controlled by laser pulses. The researchers found that the shorter the laser pulse interval, the higher the yield of SWNTs, while the SWNT structure was not affected by the pulse interval time. Using CO2 laser evaporation method for single wall carbon nanotubes at room temperature, if the use of fast imaging technology and emission spectra can be observed in morphology of smoke and carbon containing debris flow evaporation in argon, the diagnostic technology makes the growth process of single wall carbon nanotubes tracking possible. The main disadvantage of laser evaporation (ablation) is that the purity of single walled carbon nanotubes is low and easy to entangle.
Q:What is the graphite furnace electrode with a diameter of 400?
The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.
Q:Is graphite electrode good for foreign trade?
Profits can be made for foreign trade. Even if you produce it yourself. Traders take big head. Own production. It's hard for you to play. If you have a client, we can work together
Q:How large is the permissible overload current per square millimeter of the graphite electrode cross section?
Overhead wires, radiating the best conditions, allowed the current largest. The insulated wire in the house is laid in the wall, which has the worst heat release conditions and the smaller permissible current, so there are different safety currents.
Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
The ultra high power graphite electrodes produced in China are 300mm, 350mm, 400mm, 450mm, 550mm, 600mm, 650mm, 500mm and 700mm, with lengths of 1600mm, 1800mm, 2000mm, 2200mm, 2400mm and 2700mm.
Q:Classification of graphite electrodes
A graphite electrode with a current density of 18~25A/ cm 2 is used, which is mainly used in steel-making of high power arc furnace.
Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
Or did you adjust the electrode when it was installed? There are two electrode distance, two away, causing melting after different lengths.
Q:Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
Graphite here acts only as an electrode, and the real reaction on the graphite is oxygen, the galvanic cell reaction called iron oxygen corrosion
