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.
PRODUCT DETAILS
Graphite electrode is a major conduction material used in the electric smelting industry, which has the properties of superior electric conductivity, thermal conductivity, high mechanical strength, oxidation and corrosion resistance in high temperature. Graphite electrode is typically used in EAF(for smelting steel),submerged-arc furnace(for producing ferrodalloy, pure silicon, phosphor, matte, calcium carbide, etc.)And electric resistance furnace furnace, such as graphitization furnace producing graphite electrodes, glass-melting furnace, electric furnaces producing carborundum, etc.

- Q:Will the brush grease not short-circuit the commutator?
- The reverse pole surface should be clean and dry. Any grease, moisture or dust will destroy the carbon film on the commutator surface. The carbon film can not be formed or destroyed. It is very harmful. Grease material will be embedded in the joint between commutator and commutator. Under the action of electric spark, it will be carbonized and conductive. When serious, it will cause partial short circuit between the reversing pieces and reduce the service life of reversing.
- Q:Is graphite electrode good for foreign trade?
- I do graphite electrode production, but also do trade. The profit depends on the price you talked about. It should be around 2000.
- Q:Why should the carbon brush for the trolley be made of graphite?
- What you said is the graphite electrode graphite, there may be a high pure graphite graphite conductive rate so high, strong, high density, the graphite is mostly used in motor vehicles, such as generators, and electric tools.
- Q:Why is the production of one ton of ultra high power graphite electrode requires 1.05 tons of coke?
- After calcined to eliminate ash and volatile part of the points in this process will be a lot of weight loss, in the process of crushing mixing in process of baking or graphite in high temperature heat treatment, another part of the impurities were excluded, so the raw material is higher than the rate of finished products.
- Q:Why use platinum ferroalloy instead of iron as electrode?
- Its surface properties must comply with the characteristics of the additives so that they can be dispersed evenly.
- 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 to solve the problem of graphite electrode being crushed during electrolysis
- I can only use the experience of the past to tell you that if you want to save money easily, the time can be considered as the costA thick graphite stick; inexpensive
- Q:What is the composition of petroleum coke and what is its use?
- Medium sulphur and common cooked coke; used in large quantities for aluminium smelting. High sulfur, ordinary coke is used in chemical production, such as the manufacture of calcium carbide, silicon carbide, etc., but also as a metal casting and other fuels. Most of the petroleum coke produced in China belongs to low sulfur coke, which is mainly used for smelting aluminium and making graphite.
- Q:What's the use of carbon?
- Oxidation resistant coating graphite electrode. A graphite electrode coated with an antioxidant protective layer is applied to form a protective layer that is conductive and resistant to oxidation at high temperature, thereby reducing electrode consumption during steelmaking.
- Q:Graphite electrode in milling machine processing, dust is especially big, boot 5 minutes, workshop can not open the figure, what is the solution?
- Because will cause a short circuit, the best selection of bag type dust collector, our company is graphite in Linzhou, and before you like, then Xinxiang Keli machinery to help us to design a set of dust removal equipment, and then the operation almost no dust, you can consult the specific
