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 mechanical shock, high mechanical strength, high machining accuracy.

Do you know our material of the graphite electrode?
The regular power graphite electrode is made from petroleum coke with a little pitch, which meets
the state standards YB/T4088-2000
The high power graphite electrode is made form 70% petroleum coke and 30% imported needle
coke, which meets the state standards YB/T4089-2000
The ultra high power graphite electrode is made form 100% imported needle coke, which meets
the state standards YB/T 4090-200
Note: Needle coke is one kinds of very important material to produce the high grade graphite
electrode,which is rapid development in carbon graphite industry. The needle coke own the
following characteristics: low electric resistance, low dilatation coefficient, good electric and
thermal conductivity,high oxidation resistance, greater resistance to thermal and mechanical
shock, high mechanical strength, high machining accuracy, low consume.
Picture
- Q:How long is the graphite electrode machining cycle?
- The dust produced in the processing of graphite electrode is relatively large, the possible intrusion to the machine tool guide screw and spindle, which requires a corresponding machining device of graphite graphite dust machine, sealing better, because the graphite toxic.
- Q:How do graphitized electrodes differentiate between high power and low power?
- Compared with other materials of graphite anode plate has high temperature resistance, good electrical and thermal conductivity, easy machining, good chemical stability, acid and alkali resistance, low ash content; for electrolytic solution, preparation of chlorine, caustic soda, salt alkali electrolytic solution preparation; application such as graphite anode plate can be used as conductive anode electrolytic salt solution preparation of caustic soda. Graphite anode plate can be used as conductive anode in electroplating industry. It is an ideal material for electroplating. It can make electroplating products have the advantages of smoothness, delicacy, wear resistance, corrosion resistance, high brightness and not easy to change color.
- Q:What are pyrolytic graphite electrodes used for?
- In 1960s, copper is widely used as electrode material, usage rate of about 90%, about graphite only 10%; in twenty-first Century, more and more users start using graphite as the electrode material, in Europe, more than 90% above the graphite electrode material is. Copper, the once dominant electrode material, has almost lost its advantages over graphite electrodes.
- 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: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 graphite a negative pole and copper is an anode?
- Electrolysis (Electrolysis) is the current through the electrolyte solution or molten electrolyte (also called electrolyte), caused by the redox reaction in the cathode and the anode, the electrochemical cell can occur when an external DC voltage in the electrolysis process.
- Q:Can high-purity graphite be used as an electrode?
- The high purity graphite electrode has little wear and is suitable for increasing the machining of the cavity;
- Q:I remember the more lively metal, the electron?
- Metal ion is more inert electron, graphite electrode for electrolytic salt solution containing the same amount of substance A and C two metals, C first precipitated, so C is copper. In a dilute sulfuric acid with H2 precipitation, certainly not a copper. The more active metal betatopic ability is strong, have the corresponding ion electronic ability weaker. First metal ions corresponding to metal electrons are not active.
- Q:I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?
- The actual electrolysis of hydrogen sulfide, which produces no black, or impurities that are absorbed by the anode, is graphite, because the dots explain the loose particles that are absorbed on the surface
- Q:The future of graphene
- A report released recently pointed out that the Chinese Academy of Sciences, graphene research and industrialization continues to heat up, from the distribution of graphene patents in the field, including the application of technology research hot spots: layout of graphene as a electrode material of lithium ion batteries, solar battery electrode materials, thin film transistor preparation, sensor, semiconductor device, composite material preparation of transparent, touch screen display, transparent electrode
