- Q: What is the graphite furnace electrode with a diameter of 400?
- With the development of EAF steelmaking technology, the steel-making technology is developing towards large scale and ultra high power. The graphite electrode is mainly made of large size graphite electrode and ultra high power graphite electrode.
- Q: Electrolytic salt water why use iron as a cathode, all with graphite can not?
- Although iron and graphite can be used, it is better to use iron as the cathode: 1, because the cathode will be protected when it is electrolytic, that is to say, iron will be protected and will not lose electrons
- Q: Specification for graphite electrodes commonly used in steel works
- In general, the graphite electrode used in steelmaking furnace is mostly made of ordinary power and high power graphite electrode. Now, the use of ultra high power graphite electrode increases year by year, accounting for almost half of the graphite electrode.
- Q: Why should graphite paper be placed between the heater and the graphite electrode?
- Heater design, the common heater has three shapes, cylinder, cup, spiral, the vast majority of the current heater is cylindrical, as shown in figure. The spiral heater has complicated processing technology and has been eliminated. Cup shaped heater for hemispherical crucible, the bottom melt temperature is more uniform, because the processing technology is difficult, already no use. Nowadays, most of them use cylinder heaters. The cylindrical heater is not only easy to process, but also is related to the large number of flat crucible used in the direct drawing single crystal furnace.
- 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: 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: Iron and graphite as electrodes and Nacl as electrolyte solutions. Why do they produce electric current? Graphite and iron react not with solution, can they be connected by wires?
- Graphite here acts only as an electrode, and the real reaction on the graphite is oxygen, the galvanic cell reaction called iron oxygen corrosion
- Q: Graphite electrode press device
- (1) ordinary power graphite electrode, using graphite electrode with current density lower than 17A / cm 2, is mainly used in steel-making, smelting silicon, refining yellow phosphorus and other common power electric stove(2) anti oxidation coating graphite electrode. The surface is coated with an anti oxidation protective layer of graphite electrode to form a protective layer which has both conductive and high-temperature oxidation resistance, thus reducing the electrode consumption during steelmaking
- 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: Jiqiu conductive graphite electrode, how to compare with copper is relatively large resistance value?
- Look at what kind of graphite electrode you need. Now, the resistivity of ordinary power graphite electrode in our factory is 7.5-8.5. It is not clear that the graphite electrode is dipped in 6--7.3. copper
