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.

Graphite Electrode

Q: Thermal expansion coefficient of graphite: The graphite electrode in the thermal expansion coefficient is related with the diameter of the graphite electrode, you have what is the expansion coefficient of specific diameter range not to say it, I put the general heat on high power graphite electrode national Ministry of metallurgical industry YBT/4089--2000 give you a lower coefficient of expansion. For reference only

Q: How to improve the efficiency of graphite electrode milling, please tell me: When the tool is broken, it will not only stop the continuous processing of the steel, but also affect the quality of the product, which will lead to the scrap of the parts and the waste of the material. Considering the foreseeable future, the graphite electrode will occupy a high position, usually used equipment for processing graphite electrode the highest efficiency mold manufacturers will unremittingly, expand and between those determined to use the hard steel processing manufacturer competition gap. The foundation of micro cutting tools, in terms of graphite electrodes, is one of its most magical words: "high speed."". The spindle speed of the high speed machining center is up to 30000~60000r/min, and the feed speed can be increased to shorten the processing period and improve the quality of the surface and edge. The motor needed to drive this type of spindle is relatively small and light, which helps to reduce cutting power and reduce tool breakage. This is critical because many of the electrodes are complex, and their production involves small, easily broken micro tools (see Figure 1).

Q: What are the skills of hardfacing process for wear-resistant alloy powder blocks?: The hardfacing of wear-resistant alloy powder block is mostly made by carbon arc surfacing. General selection of graphite or carbon arc surfacing carbon rod and plate electrodes, which has good conductivity, high melting point;

Q: Can graphite be used as an electrode for electrolysis of silver in silver nitrate?: If it is molten, it can be made out of silverFor solution, only AgNO3+H2O== electrolysis ==Ag+HNO3+O2 is analyzedWhen the HNO3 concentration is enough, it will continue to react with Ag.... So you can't get Ag elements.

Q: Please senior doubts. The graphite electrode is used in the mold cavity In what case is graphite processing taken?: Because of the great loss of graphite electrode in finishing, it is not suitable to be used as finishing electrode material. Because of the small coefficient of thermal expansion of graphite, it can also be used as a big electrode material in perforation processing.

Q: How much does a graphite electrode cost about a ton?: According to purity and quality, the price is 1-6 tons / tonDo not calculate the processing cost

Q: What is anodized graphite?: According to the production method of brush, there are two kinds. One is colored brush, that is, metal graphite brush. One is black brush. The black brush is made of petroleum coke, pitch coke, carbon black, charcoal and natural graphite powder and so on. Some binders (such as coal tar pitch, coal tar and artificial resin etc.) are added to the black brush. The resin binder by curing brush manufactured for high resistance brush, and the calcined product called carbon brush and graphite brush (with natural graphite as the main raw material) graphitised after product called electrographite brush,

Q: 800KVA and 12500 EAF transformer data graphite electrode furnace.: The graphite electrode must be roasted by a cathode or anode baking furnace, and a large amount of harmful gas and dust will be produced during the roasting process.

Q: How do graphitized electrodes differentiate between high power and low power?: Compared with other materials of graphite anode plate has high temperature resistance, good electrical and thermal conductivity, easy machining, good chemical stability, acid and alkali resistance, low ash content; for electrolytic solution, preparation of chlorine, caustic soda, salt alkali electrolytic solution preparation; application such as graphite anode plate can be used as conductive anode electrolytic salt solution preparation of caustic soda. Graphite anode plate can be used as conductive anode in electroplating industry. It is an ideal material for electroplating. It can make electroplating products have the advantages of smoothness, delicacy, wear resistance, corrosion resistance, high brightness and not easy to change color.

Q: What is the composition of petroleum coke and what is its use?: Petroleum coke can be used for the manufacture of graphite, smelting and chemical industries, depending on its quality. For example, the quality of cooked sweet coke coke, mainly used in the manufacture of ultra high power graphite electrode and some special carbon products; needle coke in steelmaking industry is an important material new technology development of EAF steelmaking.
