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.

Made in China Very Good Quality Graphite Electrode for EAF Furnace

Q: Classification, uses and manufacturers of graphite electrodes: Graphite as electrode(1) the processing speed is faster: normally, the mechanical processing speed of graphite can be 2~5 times faster than copper, while the discharge processing speed is 2~3 times faster than copper;More material is not easily deformed: obvious advantages in the processing of thin electrodes; copper softening point at about 1000 degrees, easily deformed by heat; graphite sublimation temperature is 3650 degrees; the thermal expansion coefficient of copper is only 1/30.(2) lighter weight: the density of graphite is only 1/5 of copper. When large electrode is used for discharge machining, it can effectively reduce the burden of machine tools (EDM). It is more suitable for large-scale die applications.

Q: Why should supercapacitors use graphite as electrode material?: There are some similarities between the supercapacitor and the lithium-ion battery technology...... Typing and super capacitor is divided into three kinds: organic (carbon based, including now speculation is very powerful, Shi Moxi) principle is potential polarization of electrolyte, electrolyte and the positive and negative ion conductive material on the electron positron forming an electric double layer, high porous carbon materials.

Q: What is the difference between pyridine type nitrogen and graphite type nitrogen?: In fact, this problem is very simple, the carbon graphite is six square lattice ordered, natural graphite and artificial graphite is divided into two kinds: the classification of natural graphite flake graphite and graphite is earthy, basically it is not forming soil shaped graphite graphite, are rough machining, the battery core and do more. The use ratio of flake graphite.

Q: Graphite electrode specifications, graphite electrode manufacturers which good?: Graphite electrode to Qingdao Chenyang graphite Co., quality assurance, trustworthy, we have been purchasing graphite electrode for them, you can ask them,

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: 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: What kind of asphalt is better for natural graphite coating?: Special graphite mainly to high quality petroleum coke as raw material, coal tar or synthetic resin as binder, the raw material preparation, mixing, kneading, pressing, crushing, mixing, molding, roasting, soaking, repeatedly repeated purification and graphitization, and made the processing machine. It is generally used in the aerospace, electronics and nuclear industry sectors. It includes pure graphite, high purity, high strength, high density and pyrolytic graphite.

Q: Can high-purity graphite be used as an electrode?: The thin and deep bone electrode can not be deformed, and the pure graphite electrode is brittle. It is better to break or deform, and can bear high temperature without deformation.

Q: Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?: This is not a good estimate of the sheet graphite resistance after 5mm
