We have established the international advanced quality management system，every link from raw material to final product we have strict quality test；We resolutely put an end to unqualified products flowing into the market. At the same time, we will provide necessary follow-up service assurance.
- 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: Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
- This is to use the dust collector, the graphite itself is a semiconductor, can not be electrostatic dust removal
- Q: What kind of asphalt is better for natural graphite coating?
- Main types of graphite electrode with petroleum coke and needle coke, coal tar pitch as binder, calcination, mixing, kneading, pressing, baking and graphitization, and made the processing machine, is a conductor in an electric arc furnace to form arc release electricity for heating and melting of the charge, according to the quality index level, can is divided into ordinary power, high power and ultra high power.
- Q: What's the purpose of the electrode material?When the electrolytic molten state of NaCl is said, what is the use of the graphite electrode and the iron electrode?
- The copper electrode used for finishing size of the copper electrode discharge speed is not fast but spent graphite electrode is relatively smallRequirements of the high surface, the appearance of products are copper electrode discharge processingThe iron electrode is not clear enough to be used
- Q: How can the graphite powder be processed into high quality carburizing agent? Thank you
- If you are through the material can also be screened and then sold, usually 1-5 of the particle size, fine powder can only add adhesive column
- 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.
- 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: 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 are pyrolytic graphite electrodes used for?
- (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.
- Q: How large is the permissible overload current per square millimeter of the graphite electrode cross section?
- The safe current is decided according to the conductor wire cooling conditions, cooling conditions, the overhead line package, an insulating layer and bare, cooling conditions are also different.
