- 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: Thermal expansion coefficient of graphite
- In the graphite electrode, the national standard, the volume density in more than 1.60 of both high power graphite electrode, of course because of the national standard index is low now, the volume density of normal power graphite electrode factory can reach 1.65, such as Chengde and long carbon factory.
- Q: The reason why graphite is used as electrode
- Graphite has good thermal stabilityThe softening point of copper in 1000 degrees, easily deformed by heat, the melting point of graphite is 3850 + 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade. In comparison, the thermal expansion coefficient of graphite material is only 1/30 of copper material.
- 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: 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: 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: 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: Classification of graphite electrodes
- A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace.
- 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 are the factors that affect the electrode wear rate of machine tools?
- Effect of processing voltage on electrode wear. The processing voltage is the average voltage between the discharge time and the gap. When the voltage is lower than the power supply voltage (voltage) 25%, electrode loss will increase, which is due to the electrode and the workpiece is too close, the discharge column energy is too large, the electrodes generate heat radiation is too strong, at the same time, there are a large number of continuous arc discharge. But the working voltage is too high (partial load processing), bad conditions of thermal effect in the gap, is not conducive to the adsorption of copper electrode of carbon graphite, destroy the covering effect. Similarly, the electrode loss increase, therefore, corresponding to different processing standards should be selected to adjust the discharging gap voltage.
