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.

- 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: The difference between graphite electrode and graphite rod
- The difference between an electrode and a rod is that the electrode has a lead conductor, and the rod is not.
- 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: Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?
- In the electric arc furnace, the electric energy is released in the form of an arc, and the conductor is heated and melted. According to the quality index, the conductor can be divided into ordinary power, high power and ultra high power.
- Q: The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?
- In addition, the infiltration of water on graphite is not good, can not get the effect of dust removal. Now there are special graphite machine, sealing system. Air-cooled can be used, after all, the best air-cooled.
- 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: Graphitized coke, graphite, broken, mixed up, how to export?
- The graphite powder is soft, black and gray, greasy and polluting paper. Hardness is 1~2, along the vertical direction with the increase of impurities, its hardness can be increased to 3~5. The specific gravity is 1.9 ~ 2.3. Under isolated oxygen conditions, the melting point is above 3000 degrees Celsius and is one of the most refractory minerals. At room temperature, the chemical properties of stone toner are relatively stable, insoluble in water, dilute acid, dilute alkali and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, wear-resistant and lubricating materials.
- 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
- Q: I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?
- The problem is this. I have done the test of electrolytic copper sulfate, and the anode produced the same phenomenon. Finally, the chemistry teacher told me that it was because the graphite was broken in the process of electrolysis
- Q: What about graphite electrodes for steel mills?
- For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.
