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.

Q:Can Naiduo high temperature graphite
Graphite gasket medium: hot water, steam, oil, acid, alkali, ammonia, hydrogen, organic solvents, hydrocarbons, cryogenic liquids, etc..Maximum use pressure of graphite gasket: 30MPa.Service temperature of graphite gasket: -200~650
Q:Why is graphite conductive electrode oxidized?
Graphite electrode uses petroleum coke (carbon), pitch coke (carbon) as granule material
Q:MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?
The impact of carbon on the car is quite large, first of all, to reduce the power of the engine, that is, to make the power output uneven and gradually attenuated, in other words, more and more lack of force. Two is to increase fuel consumption, increase your financial burden.
Q:How long is the graphite electrode machining cycle?
When the cut depth is less than 0.2mm, the graphite will break down very little, and the surface quality of the side wall will be better.
Q:Classification of graphite electrodes
A graphite electrode coated with an antioxidant protective layer (graphite electrode, antioxidant). The utility model has the advantages of forming a protective layer capable of conducting electricity and resisting oxidation at high temperature, reducing electrode consumption (19%~50%) during the steelmaking process of the poly carbon graphite electrode, prolonging the service life of the electrode (22%~60%), and reducing the electric energy consumption of the electrode. The popularization and use of this technology can bring about such economic and social effects:The unit consumption of graphite electrode is less, and the production cost is reduced.The power consumption of the graphite electrode is less, the energy consumption per unit of steelmaking is saved, the production cost is saved, and the energy saving is saved.Because the number of graphite electrodes is changed less, the labor quantity and danger coefficient of operators are reduced, and the production efficiency is improved.Graphite electrode is a kind of low consumption and low pollution product. It has a very important social significance in today's energy saving, emission reduction and environmental protection.
Q:What is the composition of petroleum coke and what is its use?
Mainly used for making carbon products, such as graphite electrodes, anode arc, steel, non-ferrous metals, with aluminum for use; silicon carbide products, such as grinding wheel, rubber, sandpaper; producing goods for the production of synthetic fiber, calcium carbide acetylene and other products; also can be used as fuel for fuel, but for grading impact for grinding superfine grinding, through the JZC-1250 device can be made of coke powder after combustion, using coke powder as fuel is mainly some glass factory, coal water slurry plant etc..
Q:Electrolysis of CuCl2 solutions with graphite electrodes
After energization, electrolysis occurs, not ionizationIonization does not require energization, and can occur in aqueous or molten state.
Q:Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
What happens is oxygen etching negative pole: Fe-2e-=Fe2+ positive electrode: O2+2H2O+4e-=4OH-, of course, the current is produced.
Q:Synthesis techniques of carbon nanotubes
Catalytic pyrolysis is one of the widely used methods for preparing carbon nanotubes. The method mainly uses transition metal as catalyst, and is suitable for large-scale preparation of carbon nanotubes. The content of carbon nanotubes in the products is higher, but the defects of carbon nanotubes are more.
Q:Graphite can be used in acid towers in chemical plants because of graphite
The popularization and use of this technology can bring about such economic and social effects: (1) the consumption of graphite electrode units is less, and the production cost is reduced. For example, a steel plant, according to the annual production level did not occur in LF refining furnace 35 week graphite electrode, refining furnace 165 consumption calculation, using anti oxidation technology of graphite electrode, graphite electrode can save 373 per year(153 tons) electrode, each year ultra high power electrode 16900 yuan computation, can save 2 million 585 thousand and 700 yuan rmb.
