Graphite Electrode for Proudcing Alloy Steels

 

 Composite of Graphite Electrode for Proudcing Alloy Steels

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 Proudcing Alloy Steels:

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:800KVA and 12500 EAF transformer data graphite electrode furnace.
Graphite project: Project Description: steel furnace and iron smelting furnace, ferrosilicon smelting, electrolytic aluminum and so on, all use large surface graphite electrode.
Q:What do carbon products include?
High power electrode and ultra high power electrode. The carbon block can be divided into blast furnace carbon block, aluminum carbon block and electric furnace block. Carbon products can be divided into carbon products, graphite products, carbon fibers and graphite fibers according to the depth of processing. Carbon products can be divided into graphite products, carbon products, carbon fibers and special graphite products according to the raw materials and the production process. Carbon products according to their ash content, and can be divided into multi gray products and less ash products (including ash below l%).
Q:Why should the carbon brush for the trolley be made of graphite?
Graphite conducts electricity and is self lubricant, resistant to wear. As for why, high school chemistry textbooks have ah.
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: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: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:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
This is to use the dust collector, the graphite itself is a semiconductor, can not be electrostatic dust removal
Q:Graphite electrode specifications, graphite electrode manufacturers which good?
Graphite electrode to Qingdao Chenyang graphite Co., quality assurance, trustworthy, we have been purchasing graphite electrode for them, you can ask them,
Q:What kind of asphalt is better for natural graphite coating?
Special graphite mainly to high quality petroleum coke as raw material, coal tar or synthetic resin as binder, the raw material preparation, mixing, kneading, pressing, crushing, mixing, molding, roasting, soaking, repeatedly repeated purification and graphitization, and made the processing machine. It is generally used in the aerospace, electronics and nuclear industry sectors. It includes pure graphite, high purity, high strength, high density and pyrolytic graphite.
Q:Will the brush grease not short-circuit the commutator?
The brush of motor is usually made of pure graphite electrode, electrochemical graphite electrode and metal fossil ink electrode material. Because it contains graphite, it has conductive effect on the one hand
