Product Description:

 

Graphite Electrode for Electric Arc Furnace

 

 Composite of Graphite Electrode for Electric Arc Furnace:

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.

 

Applications of Graphite Electrode for Electric Arc Furnace:

It is used for the electric arc furnace steel making. (About 70-80% graphite electrode is used for steel making).

It is used for the submerged arc furnace, including melting iron alloy, pure silicon, yellow

phosphorus,matte, calcium carbide and so on.

It is used for the resistance furnace, such as the graphite making, melting glass, silicon carbide

making and so on.

Q:How can the graphite powder be processed into high quality carburizing agent? Thank you
Basically, it can no longer be a "good" carburizing agent
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:Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?
Look at what kind of graphite electrode you need. Now, the resistivity of ordinary power graphite electrode in our factory is 7.5-8.5. It is not clear that the graphite electrode is dipped in 6--7.3. copper
Q:The reason why graphite is used as electrode
Graphite is good in plasticity and easier to be machined preciselyGraphite material has the advantages of high processing accuracy and good surface effect, especially in the processing of precise, complex, thin-walled and Gao Ying material mold cavity. Because the cutting resistance of graphite is only 1/5 of copper material, it is easier to do manual grinding and polishing on the operation. There is no burr after graphite processing, and it is easier to realize automatic production. Complex geometric modeling can be realized.
Q:What is the composition of petroleum coke and what is its use?
Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.
Q:I remember the more lively metal, the electron?
C is a salt solution of copper metal because copper is first reduced to a single element on a graphite electrode.Moreover, the addition of dilute sulfuric acid has a H2 emission, then a H of the previous metal.
Q:Why should supercapacitors use graphite as electrode material?
Because graphite material, light weight, good thermal conductivity and conductivity.
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:What's the use of carbon?
High power graphite electrode. Allows the use of current density of 18 ~ 25A/ cm 2 graphite electrode, mainly used in steel-making high power arc furnace
Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
Connect the fan with a thicker pipe and suck it out of the workshop. The air inlet is mounted on the milling head. Reduce milling speed properly.
