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

- Inquire about price/MOQ

Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
Most of the graphite electrodes are cylindrical, but also have square and multi ribbed shapes. Graphite blank refers to the firing of raw materials without processing graphite.
Q:How about graphite electrode high-temperature oxidation resistant coating?
Heat resistant coating is generally able to withstand 300 degrees below the temperature, commonly used aluminum heat-resistant paint, high temperature resistance can withstand higher temperatures, such as 800 degrees or more, commonly used silicone heat-resistant paint
Q:How to improve the efficiency of graphite electrode milling, please tell me
The technical development of the high-speed machining center lays the foundation for improving the milling efficiency and quality of the graphite electrode, especially for the milling of the small electrode with complicated shape and thin wall. In the EDM mold processing, the graphite electrode needs to be processed by the high-speed machining center (HSM), so the demand for HSM machine tools is also increasing. But for some time, because of the technological developments in hard steel processing, it seems possible to make graphite electrodes an obsolete technology.
Q:The production of one ton of steel required graphite electrode
The consumption of graphite electrode in steelmaking in arc furnace, according to the different material, different specifications of graphite electrode used (normal power graphite electrode, high power graphite electrode, ultra high power graphite electrode) have relations.
Q:Excuse me, why does the graphite electrode flake when electrolyzed salt water is used?
The structure of the electrolytic cell is different when the electrolytic cell is constructed with different electrolytes
Q:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?
Can't。 During electrolysis, there is depletion of sulfite ions.
Q:What is anodized graphite?
Anodized graphite is mainly used for making brushes. The utility model has the advantages of good performance, high resistance coefficient and contact voltage, favorable for suppressing spark, and wide application range, and can be used for various types of motors and motors with more difficult commutation conditions.
Q:What is the graphite furnace electrode with a diameter of 400?
With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
Q:Can high-purity graphite be used as an electrode?
The thin and deep bone electrode can not be deformed, and the pure graphite electrode is brittle. It is better to break or deform, and can bear high temperature without deformation.
Q:Where is the graphite electrode scrap?
Finally, a bright white Ar-ICP discharge is formed, especially like a drop of water droplets.
