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.

Made in China Graphite Electrode for EAF Furnace Very Good Quality

Q:Classification, uses and manufacturers of graphite electrodes: Classification of graphite electrodes:(1) common power graphite electrode (RP), (2) high power graphite electrode (HP), (3) quasi ultra high power graphite electrode (SHP), (4) ultra high power graphite electrode (UHP) Note: poly carbon classification method

Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?: After calcined to eliminate ash and volatile part of the points in this process will be a lot of weight loss, in the process of crushing mixing in process of baking or graphite in high temperature heat treatment, another part of the impurities were excluded, so the raw material is higher than the rate of finished products.

Q:Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?: Graphite electrodes react with oxygen to form carbon dioxide, soluble in water

Q:What is the application of wire cutting with graphite electrode?: Greatly shorten the preparatory time of mechanical processing, and improve the level of automation of the whole process of machining, and also enhance the ability of the manufacturing system to adapt to changes in production conditions.

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:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?: The temperature is not enough, the composition of graphite is carbon, of course, flammable, but each kind of object burning point is not the same, the nature of graphite is relatively stable, burning point is very high, cigarette lighter this temperature is certainly not burning up.Useful words, remember to adopt Oh, thank you ~!

Q:The use of graphite as an electrode in alumina electrolysis: Graphite acts as an electrode:The electrical conductivity of graphite, the electrode itself must be electrically conductive;When graphite acts as an anode, it acts as a reducing agent and displaces an element of aluminum in a chemical reaction;Graphite is cheap and cost saving.

Q:Is the anode of electrolytic water suitable for ordinary titanium wires?: Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.

Q:Why is graphite a negative pole and copper is an anode?: The process of causing a chemical change by passing through a substance. Chemical change is the process in which material is lost or obtained by electrolysis (oxidation or reduction). Electrolysis is performed in an electrolytic cell. The electrolytic cell is composed of two electrodes, yin and Yang, which are respectively immersed in the solution containing positive and negative ions. The current into the negative electrode (cathode), are positively charged ions migrate to the cathode solution, and with the combination of electronic elements, become neutral or negatively charged molecules; negative ion transfer to another electrode (anode), electrons are given into neutral elements or molecules.

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.
