Q:Graphite electrode specifications, graphite electrode manufacturers which good?
The key is you use and what type of need, say, abroad, what Dongyang, sigley are good, but also, very expensive, you can also choose to try our home
Q:Graphite is made of high-strength graphite, it is a kind of graphite grade specification.
Most of the graphite electrodes are cylindrical, but also have square and multi ribbed shapes. Graphite blank refers to the firing of raw materials without processing graphite.
Q:How to improve the efficiency of graphite electrode milling, please tell me
There are many factors that determine the need to continue producing graphite electrodes, so high-speed machining has become a key manufacturing process in the die manufacturing industry. Compared with the time required for the milling of graphite electrodes, the processing of high rigidity hard steel still takes longer. When milling dies, cavities, and complex 3D surfaces on hard steel, radial runout errors and tool deviations often result in fracture of the tool. 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.
Q:What is the difference between pyridine type nitrogen and graphite type nitrogen?
The fine structure graphite is the raw material used in the production of graphite electrode. The particle size is relatively small, generally below 0.5.
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:Do electroplating experiments, graphite as an electrode, graphite how to pre process to ensure that the coating will not fall, resulting in increased color of the solution
Graphite as anode, generally do not need special treatment, but to choose high purity, high density, high strength (so-called "three high" graphite) graphite on the line, this graphite in brush plating operations are often used as anode material.
Q:Graphite graphite graphite graphite electrode what is the use?
The graphite electrode can be divided into artificial graphite electrode and natural graphite, artificial graphite electrode is the main raw material of petroleum coke and pitch coke, made after graphitization process of the natural graphite electrode is better than that of artificial graphite electrode, and does not require the graphitization process is complex, it can save energy, therefore, natural graphite electrode the rapid development in recent years.
Q:What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?
The ultra high power graphite electrodes produced in China are 300mm, 350mm, 400mm, 450mm, 550mm, 600mm, 650mm, 500mm and 700mm, with lengths of 1600mm, 1800mm, 2000mm, 2200mm, 2400mm and 2700mm.
Q:Is graphite flammable?Why do I bake pencil cores with a fever that doesn't burn?
The temperature is not enough, the composition of graphite is carbon, of course, flammable, but each kind of object burning point is not the same, the nature of graphite is relatively stable, burning point is very high, cigarette lighter this temperature is certainly not burning up.Useful words, remember to adopt Oh, thank you ~!
Q:Which department in the steel plant needs graphite in large quantities?
Steelmaking department. 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
