Graphite Electrode
Graphite electrode is made from the domestic first class 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, ultra high power and square electrode. The range of diameters covers from 200mm to 800mm. Our products own the following characteristics: low electric resistivity, good electrical and thermal conductivity, high oxidation resistance, greater resistance to thermal and mechanical shock, high mechanical strength, high machining accuracy.
CNBM and its partner have 4 production bases and the annual production capacity of graphite electrodes is 60,000 MT.

FAQ
Q:Are you a trading company or manufacturer?
A:CNBM is a large-scale central governmental industrial group with its own manufacturing sector, research and development sector, trading sector and logistics sector.

Q:I have some special requirement about specifications.
A:We have a well-rounded product range, which endows us with the capability of applying many special specifications. Please feel free to contact us with yours.

Q:Do you accept OEM service?
A:Yes, we do.

Q:What is your delivery time?
A:It depends on the size/complexity of your order and our own production schedule. Usually we provide a faster delivery than the industry's average.

Q:What is the payment term?
A:Our payment terms are negotiable.

Q:Can I have my own logo on the product?
A:Sure, we can apply your own logo on the products according to your requirement.

Q:The reason why graphite is used as electrode
Graphite has good thermal stabilityThe softening point of copper in 1000 degrees, easily deformed by heat, the melting point of graphite is 3850 + 50 DEG C, the boiling point of 4250 DEG C, even after the ultra high temperature arc ignition, the weight loss is very small, the thermal expansion coefficient is small. The strength of graphite increases with the increase of temperature, and the strength of graphite is doubled at 2000 degrees centigrade. In comparison, the thermal expansion coefficient of graphite material is only 1/30 of copper material.
Q:Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?
But because the silicon carbide is too hard, it is difficult to machining, good workability, such as non special requirements, using graphite instead of silicon carbide, instead of the effect is not good, but can use a silicon carbide, easy processing, small life than silicon carbide.
Q:Are graphite and carbon electrodes the same? What kinds of ore furnaces are used?
Graphite electrode should be relatively pure, composed of graphite.
Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?
The shorter one is the farther away from the other, and the shorter one is the shorter one
Q:The use of graphite as an electrode in alumina electrolysis
Graphite acts as an electrode:The electrical conductivity of graphite, the electrode itself must be electrically conductive;When graphite acts as an anode, it acts as a reducing agent and displaces an element of aluminum in a chemical reaction;Graphite is cheap and cost saving.
Q:How long is the graphite electrode machining cycle?
The dust produced in the processing of graphite electrode is relatively large, the possible intrusion to the machine tool guide screw and spindle, which requires a corresponding machining device of graphite graphite dust machine, sealing better, because the graphite toxic.
Q:Why should supercapacitors use graphite as electrode material?
Because graphite material, light weight, good thermal conductivity and conductivity.
Q:How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done
Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable
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 a negative pole and copper is an anode?
Graphite, as an electrode material, can conduct electricity, which belongs to an inert electrode. It only acts as a conductive agent, but does not participate in the electrolytic reaction process. So the anode is made, and copper is oxidized in the electrolysis of monovalent cations, so copper is used as the anode.
