G grade Carbon Electrode 1020-1400 CNBM Silicon Production

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 graphite can be used as conductive material?: Graphite used in the electrical industry requires a high degree of particle size and grade. Such as alkaline batteries and some special electric carbon products, requiring graphite particle size control within the scope of the project, grade above, harmful impurities are required in the following. The graphite used in a picture tube for television is required below. As a wear-resistant and lubricating material, graphite is often used as a lubricant in the mechanical industry.

Q: What is the difference between pyridine type nitrogen and graphite type nitrogen?: The fine structure graphite is the raw material used in the production of graphite electrode. The particle size is relatively small, generally below 0.5.

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?: The graphite is cheaper and easier to obtain, but the carbon electrodes sold in the general market are not very pure at most times. The experiment is done for a period of time, and the carbon is inexplicably broken, especially if you need to work for a long time. So, if your graphite electrode is of good quality, it's still graphite.

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?: The oxygen will react with the graphite and the gas will dissolve.The iron has been oxidized.

Q: Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?: Ultra high power electrode of the main raw material is coke, but in order to increase the strength of the product will add some metallurgical coke, another is in the process of producing stains in coal tar pitch in after graphitization has become one of the A

Q: The graphite electrode made by the machining center adopts cooling method, which is water cooled, oil cooled and blow cold. Which is good?: Use oil cold. Air cooling will cause graphite dust flying, on the one hand, toxic, on the one hand there are security risks (caused by circuit short circuit). Water cooling is virtually out of use, taking into account the maintenance and maintenance of the CNC.

Q: After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?: Or did you adjust the electrode when it was installed? There are two electrode distance, two away, causing melting after different lengths.

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.
