Product Description:

Description: 

Graphite electrode is made from the domestic first petroleum 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.

Note: The consumption of Electric Arc Furnace(EAF) is about 3-5kg per ton steel. The Ladle Furnace(LF) is about 1kg per ton steel. The converter with Ladle Furnace(LF) is about 0.5kg per ton steel. All the information is for your reference. There are many factors can influence the consumption, such as the kinds of steel, conduction time, process production and so on. So if you have any question, please don’t hesitate to contact us.


FAQs:

Q1  What’s the transport method?

A1  FCL delivery goods with wooden pallet; If LCL delivery, must with wooden case; Sometimes need open top, flat rack or bulk cargo.

Q2  What’s the required payment term?

A2  Generally 30% TT as the prepayment, 70% TT before delivery. If need, 100% Irrevocable Letter of Credit or negotiation.

Q3  Which country are our products exported to?

A3  Apart from entire Chinese market, the US, Russia, Japan, Korea, Australia and some Southeast Asian Nations.

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?
Anodic iron is directly oxidized without oxygen generation
Q:How about graphite electrode high-temperature oxidation resistant coating?
The utilization ratio of graphite energy can reach more than 95%. Many kinds of antioxidant paint, it is recommended to directly find their technicians, you can give professional advice, according to the actual situation, the reasonable use of high-temperature oxidation resistant paint.
Q:Synthesis techniques of carbon nanotubes
Laser evaporation is an effective method for the preparation of single-walled carbon nanotubes. Single walled carbon nanotubes and single-walled carbon nanotube bundles were prepared by evaporation of carbon targets doped with Fe, Co, Ni or their alloy by high energy CO2 laser or Nd/YAG laser. The diameter of the tubes can be controlled by laser pulses. The researchers found that the shorter the laser pulse interval, the higher the yield of SWNTs, while the SWNT structure was not affected by the pulse interval time. Using CO2 laser evaporation method for single wall carbon nanotubes at room temperature, if the use of fast imaging technology and emission spectra can be observed in morphology of smoke and carbon containing debris flow evaporation in argon, the diagnostic technology makes the growth process of single wall carbon nanotubes tracking possible. The main disadvantage of laser evaporation (ablation) is that the purity of single walled carbon nanotubes is low and easy to entangle.
Q:National standard for graphite electrodes
Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB
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:Why use platinum ferroalloy instead of iron as electrode?
General industrial grade silicon dioxide, because the preparation technology is different, can be divided into two types, one is dry, sintered (Fume Type), a wet precipitation type (Precipitated Type), and two of the surface area, the surface with hydroxyl (-OH) are the same, in general, the former the latter is more, less, the two surface has the tendency of hydrophilic, as for lipophilic polymer, such as paint, rubber... Etc.,... If the silica surface pre rendered hydrophobic, has a good effect.
Q:How large is the permissible overload current per square millimeter of the graphite electrode cross section?
Overhead wires, radiating the best conditions, allowed the current largest. The insulated wire in the house is laid in the wall, which has the worst heat release conditions and the smaller permissible current, so there are different safety currents.
Q:What is the application of wire cutting with graphite electrode?
Machine: wire cutting wire, wire EDM, wire EDM wire is the cutting machine.
Q:What is the difference between SGL graphite electrode and graphite electrode in general?
Can not say that the more detailed the better, is relative, must be uniform within the range (after all, it is very important to choose the aggregate), such as spectral pure graphite, is not due, he is a lot of technology to producing stains, then burning, and then producing stains, the strength is quite good,
Q:What is the striking electrode in the die making? Where is the technical point?
Electrical discharge machining (EDM) is a spark discharge in a liquid medium at a lower voltage range to meet the required shape and size.
