PRODUCT DETAILS

Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity, thermal conductivity, high mechanical strength, oxidation and corrosion resistance in high temperature. Graphite electrode is typically used in EAF(for smelting steel),submerged-arc furnace(for producing ferrodalloy, pure silicon, phosphor, matte, calcium carbide, etc.)And electric resistance furnace furnace, such as graphitization furnace producing graphite electrodes, glass-melting furnace, electric furnaces producing carborundum, etc.

- Inquire about price/MOQ

Q:Why is graphite conductive electrode oxidized?
Graphite electrode uses petroleum coke (carbon), pitch coke (carbon) as granule material
Q:How much does a graphite electrode cost about a ton?
According to purity and quality, the price is 1-6 tons / tonDo not calculate the processing cost
Q:What is the composition of petroleum coke and what is its use?
Mainly used for making carbon products, such as graphite electrodes, anode arc, steel, non-ferrous metals, with aluminum for use; silicon carbide products, such as grinding wheel, rubber, sandpaper; producing goods for the production of synthetic fiber, calcium carbide acetylene and other products; also can be used as fuel for fuel, but for grading impact for grinding superfine grinding, through the JZC-1250 device can be made of coke powder after combustion, using coke powder as fuel is mainly some glass factory, coal water slurry plant etc..
Q:What is the striking electrode in the die making? Where is the technical point?
Electrical discharge machining (EDM) is a spark discharge in a liquid medium at a lower voltage range to meet the required shape and size.
Q:I remember the more lively metal, the electron?
C metal is copper, because a dilute sulfuric acid into the H2 precipitation, then definitely not copper. And the inactive first precipitate
Q:What kinds of carbon are there?
Graphite electrode class can be divided into ordinary power graphite electrode according to the allowable current density. High power electrode and ultra high power electrode.
Q:What about graphite electrodes for steel mills?
The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys
Q:Where is the graphite electrode scrap?
Vortex ring formed in a highly ionized internal ICP can be regarded as the secondary coil of the transformer is only one turn, and the work coil water is equivalent to the primary winding of the transformer, the coupling between them, the strength and direction of the magnetic field varies with time, the electronic and ionic field acceleration continuously changes its direction of motion. Lead to Joule heating effect and incidental ionization. This gas forms a new and stable "electric flame" light source in the quartz torch tube in a very short time.
Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
In theory, as long as a certain temperature is reached, any substance can be burned, and the diamond is converted to graphite at 2000~3000 DEG C under anaerobic conditions. That is to say, graphite (flake graphite)
Q:Which department in the steel plant needs graphite in large quantities?
Steelmaking department. The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements.
