Product 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 mechanicalshock, high mechanical strength, high machining accuracy.

Q:Graphitized coke, graphite, broken, mixed up, how to export?
Graphite fossil oil coke is the best smelting carburizing agent. In the steel-making industry, to produce good steel, there must be good raw materials, including good carburizing agent, and the graphitization of petroleum coke is the best carburizing agent.
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?
1. graphite (two kinds of EDM3 and EDM200)2. copperIn general, graphite electrode for extensive escape material (graphite texture loose, discharge energy is relatively large, removal of materials faster, but face flowers that roughness is relatively large
Q:What is the role of the Pt electrode? What is the difference between the graphite electrode and the graphite electrode?
Carbon electrodes, however, are less likely to be less controllable because of their microstructure, or have some effect on the electric field, if they are sensitive signals
Q:What about graphite electrodes for steel mills?
The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys
Q:Synthesis techniques of carbon nanotubes
Catalytic pyrolysis is one of the widely used methods for preparing carbon nanotubes. The method mainly uses transition metal as catalyst, and is suitable for large-scale preparation of carbon nanotubes. The content of carbon nanotubes in the products is higher, but the defects of carbon nanotubes are more.
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:What are the skills of hardfacing process for wear-resistant alloy powder blocks?
Because the carbon containing ash, a graphite resistor 2-3 times, so the use of graphite electrode is better.
Q:What are the factors that affect the electrode wear rate of machine tools?
In the pulse peak voltage, current and pulse width decreased, the electrode loss increase, and the heat produced from the processing of large pulse width, is conducive to the adsorption of copper electrode graphitization induced by carbon, which is commonly referred to as the covering effect".
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 is the application of wire cutting with graphite electrode?
Machine: wire cutting wire, wire EDM, wire EDM wire is the cutting machine.
