Product Description

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. Our products own the following characteristics: low electric resistance, good electric and

thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.

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

shock, high mechanical strength, high machining accuracy, low consume.

Graphite Electrode/High Purity CNBM Graphite

Q: Is graphite electrode good for foreign trade?: Foreign sales commission depends on the price you talk to the customer, and the profit is objective.

Q: Where is the graphite electrode scrap?: Finally, a bright white Ar-ICP discharge is formed, especially like a drop of water droplets.

Q: After electrolysis of CuCl2 solution with graphite electrode for a period of time, we can observe that the graphite surface attached to the DC power supply is attached to the red material,And will the color of the solution be deep or shallow?: Negative poleThe color becomes lighter (the copper ion gets electrons in the cathode and becomes copper)

Q: Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?: The temperature is not enough, the composition of graphite is carbon, of course, flammable, but each kind of object burning point is not the same, the nature of graphite is relatively stable, burning point is very high, cigarette lighter this temperature is certainly not burning up.Useful words, remember to adopt Oh, thank you ~!

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: The use of graphite as an electrode in alumina electrolysis: The technical knowledge of electrolytic aluminum, cleaning and maintenance of alumina equipment, you can search for Baidu on the green, looking for.

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: Graphite powder produced by graphite electrode and what we usually call graphite is a kind of thing?: Graphite electrode is mainly in petroleum coke, coke as raw material

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: What is the difference between SGL graphite electrode and graphite electrode in general?: In fact, the graphite electrode abroad (including Japan) in several ways than we can control the fine, one is pure, another is anisotropic (resistance, thermal conductivity ah) usually do some control, in the strength of domestic now is also doing well, but when we are comparing high quality products, general domestic products it is basically a piece of the indicators are poor
