Q: Why is graphite conductive electrode oxidized?: Graphite electrode uses petroleum coke (carbon), pitch coke (carbon) as granule material

Q: Thermal expansion coefficient of graphite: In the graphite electrode, the national standard, the volume density in more than 1.60 of both high power graphite electrode, of course because of the national standard index is low now, the volume density of normal power graphite electrode factory can reach 1.65, such as Chengde and long carbon factory.

Q: What are the skills of hardfacing process for wear-resistant alloy powder blocks?: Because the carbon containing ash, a graphite resistor 2-3 times, so the use of graphite electrode is better.

Q: Where is the graphite electrode scrap?: Vortex ring formed in a highly ionized internal ICP can be regarded as the secondary coil of the transformer is only one turn, and the work coil water is equivalent to the primary winding of the transformer, the coupling between them, the strength and direction of the magnetic field varies with time, the electronic and ionic field acceleration continuously changes its direction of motion. Lead to Joule heating effect and incidental ionization. This gas forms a new and stable "electric flame" light source in the quartz torch tube in a very short time.

Q: What is the graphite furnace electrode with a diameter of 400?: The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace.

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 is graphite a negative pole and copper is an anode?: Graphite, as an electrode material, can conduct electricity, which belongs to an inert electrode. It only acts as a conductive agent, but does not participate in the electrolytic reaction process. So the anode is made, and copper is oxidized in the electrolysis of monovalent cations, so copper is used as the anode.

Q: Carbon graphite electrode and what is the difference?: Graphite electrode is a mixture of natural graphite and petroleum coke and asphalt coke. After being treated by high temperature graphitization, the material is composed of graphite;

Q: What is anodized graphite?: Anodized graphite is mainly used for making brushes. The utility model has the advantages of good performance, high resistance coefficient and contact voltage, favorable for suppressing spark, and wide application range, and can be used for various types of motors and motors with more difficult commutation conditions.

Q: What are pyrolytic graphite electrodes used for?: The weight is lighter: the density of graphite is only 1/5 of copper. When the large electrode is used for EDM, it can effectively reduce the burden of machine tools (EDM). It is more suitable for applications on large moulds.

Our products have been sold to Europe, Southeast Asia, South America, India, and other countries and regions. Meanwhile, Our Graphite Electrodes and nipples have already been ISO9001:2000 approved. We will pay attention to product quality and offer you the best price. We hope that we could establish business relationships with all friends on the basis of equality and mutual benefits.
