Product Description:

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 mechanicalshock, high mechanical strength, high machining accuracy.

Graphite Electrodes Features:

RP HP UHP Graphite Electrode

Q:How large is the permissible overload current per square millimeter of the graphite electrode cross section?: 9A/mm2 safety current should be bare overhead, 5A/mm2 is obviously insulation lines, the indoor environment standards.

Q:The production of one ton of steel required graphite electrode: Can not generally say, a ton of steel production consumes much of graphite electrode.

Q:What are pyrolytic graphite electrodes used for?: In 1960s, copper is widely used as electrode material, usage rate of about 90%, about graphite only 10%; in twenty-first Century, more and more users start using graphite as the electrode material, in Europe, more than 90% above the graphite electrode material is. Copper, the once dominant electrode material, has almost lost its advantages over graphite electrodes.

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: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:National standard for graphite electrodes: Page 7 the international standard specifies the shape, dimensions and tolerances, technical requirements, test methods, packaging, marking, storage, transportation and quality certificates of graphite electrodes. This standard applies to high quality petroleum coke, asphalt, coke as the main raw material, through molding, roasting, impregnation, graphitization and mechanical processing made of, power supply arc furnace as conductive material of ordinary power graphite electrode. Common power graphite electrode GB

Q:Will the concentration of electrolytic sodium sulfite be increased with graphite as electrode?: No, sodium sulfite reacts with the oxygen produced.

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.

Q:What does graphite electrode GSK mean?: Graphite board material is GSK, GSK refers to model specifications

Q:I remember the more lively metal, the electron?: C is a salt solution of copper metal because copper is first reduced to a single element on a graphite electrode.Moreover, the addition of dilute sulfuric acid has a H2 emission, then a H of the previous metal.
