Production Description:

Graphite electrode is made from the domestic first petroleum coke and high quality needle coke and widely used in the electric arc furnaces for production of alloy steels, metal and other nonmetallic materials, etc. The graphite electrodes include regular power, high power, super high power, ultra high power and square electrode. The range of diameters covers from 200mm to 700mm. Our products own the following characteristics: low electric resistance, good electric and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.

 

 

 

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.

Q:Can Naiduo high temperature graphite
The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..
Q:What is the difference between SGL graphite electrode and graphite electrode in general?
In fact, the graphite electrode abroad (including Japan) in several ways than we can control the fine, one is pure, another is anisotropic (resistance, thermal conductivity ah) usually do some control, in the strength of domestic now is also doing well, but when we are comparing high quality products, general domestic products it is basically a piece of the indicators are poor
Q:Why is graphite conductive electrode oxidized?
Graphite electrode uses petroleum coke (carbon), pitch coke (carbon) as granule material
Q:How long is the graphite electrode machining cycle?
The dust produced in the processing of graphite electrode is relatively large, the possible intrusion to the machine tool guide screw and spindle, which requires a corresponding machining device of graphite graphite dust machine, sealing better, because the graphite toxic.
Q:Why should the carbon brush for the trolley be made of graphite?
Graphite has good conductivity
Q:Why is graphite a negative pole and copper is an anode?
Graphite, as an electrode material, can conduct electricity, which belongs to an inert electrode. It only acts as a conductive agent, but does not participate in the electrolytic reaction process. So the anode is made, and copper is oxidized in the electrolysis of monovalent cations, so copper is used as the anode.
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: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?
What happens is oxygen etching negative pole: Fe-2e-=Fe2+ positive electrode: O2+2H2O+4e-=4OH-, of course, the current is produced.
Q:Can high-purity graphite be used as an electrode?
The utility model has the advantages of small density and suitable tool electrodes for processing large parts or moulds, and the whole quality is small.
Q:Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?
Graphite electrode should be relatively pure, composed of graphite.
