Production 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.

Applications

Used in EAF and LF for steel making, as well as in electric smelting furnace for producing industrial silicon, phosphorus, etc.

Programmable properties
1.Good electrical conductivity
2.High resistance to thermal shock
3.High mechanical strength

Grades:RP, RPI, HP, SHP, UHP

Graphite Electrode RP Grade

Q: What are the skills of hardfacing process for wear-resistant alloy powder blocks?: The power supply adopts the DC arc welding machine with steep drop characteristic, adopts the positive connection method, the electrode is negative, and the electrode is a high strength spectrum pure graphite rod,

Q: Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?: In anaerobic conditions, the ignition temperature is at least above 3000 degrees. There are many types of graphite, different types of ignition points, and the burning point of pyrolytic graphite...

Q: MITSUBISHI machine graphite electrode processing, how does not accumulate carbon?: Carbon deposition can cause insufficient combustion of gasoline and cause engine chattering.

Q: Classification of graphite electrodes: A graphite electrode with a current density of 18~25A/ cm 2 is used, which is mainly used in steel-making of high power arc furnace.

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?: Graphite here acts only as an electrode, and the real reaction on the graphite is oxygen, the galvanic cell reaction called iron oxygen corrosion

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: What do carbon products include?: Carbon and graphite materials are mainly carbon based non-metallic solid materials, in which carbon material is basically composed of non graphitic carbon material, and graphite material is basically composed of graphite carbon material. For the sake of simplicity, carbon and graphite materials are sometimes referred to as carbon materials (or carbon materials).

Q: I used 12V direct current, graphite electrode electrolysis sodium sulfide solution, the anode produced a large number of black material, this is why ah?: The actual electrolysis of hydrogen sulfide, which produces no black, or impurities that are absorbed by the anode, is graphite, because the dots explain the loose particles that are absorbed on the surface

Q: What about graphite electrodes for steel mills?: The graphite electrode steelmaking is to enter the electric energy through the graphite electrode to the electric arc furnace, and takes the arc between the electrode end and the furnace charge as the heat source to carry on the steel smelting. The electric arc furnace takes electric energy as heat source, and can adjust the atmosphere in the furnace. It is very beneficial to smelt the steel which contains more easily oxidized elements. Smelting a variety of alloys

Q: How about graphite electrode high-temperature oxidation resistant coating?: Can be used, temperature characteristics of nano composite ceramic coating is more stable, and nano composite ceramic nano high temperature oxidation resistant coatings of different graphite products according to the use conditions, can the temperature of 1600 degrees, forming a dense coating on graphite coated with rust, corrosion, high temperature resistance, oxidation resistance, wear resistance and other properties.

We enjoy convenient access to major transportation networks. Furthermore, all our products are manufactured with advanced equipment and strict QC procedures in order to ensure high quality.
