Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?: Connect the fan with a thicker pipe and suck it out of the workshop. The air inlet is mounted on the milling head. Reduce milling speed properly.

Q:In EDM, the electrodes are made of graphite and copper. Please tell us the difference between them: For operators, copper is certainly better, graphite will have dust, the human body has serious harm

Q:What are pyrolytic graphite electrodes used for?: Discharge consumption; because the spark oil also contains C atoms in the discharge process, high temperature oil spark decomposition of C atom, and form a protective film on the surface of the graphite electrode, graphite electrode loss compensation.

Q:What is the composition of petroleum coke and what is its use?: Medium sulphur and common cooked coke; used in large quantities for aluminium smelting. High sulfur, ordinary coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting and other fuels. Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used for smelting aluminium and making graphite.

Q:What is anodized graphite?: Anodized graphite is mainly used for making brushes. The utility model has the advantages of good performance, high resistance coefficient and contact voltage, favorable for suppressing spark, and wide application range, and can be used for various types of motors and motors with more difficult commutation conditions.

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 should the carbon brush for the trolley be made of graphite?: Graphite conducts electricity and is self lubricant, resistant to wear. As for why, high school chemistry textbooks have ah.

Q:Which department in the steel plant needs graphite in large quantities?: 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.

Q:Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?: The main components of carbon electrodes are graphite, carbon powder and other impurities which are not converted into graphite. The resistivity is higher than that of graphite electrode. These electrodes are mostly used in electric furnace steelmaking, smelting aluminium oxide and other electric arc furnaces.

Q:What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found: The graphite part is called pyrolytic graphite. Stronger than ordinary graphite, strong oxidation resistance.
