S grade Carbon Electrode 1020-1400 CNBM Silicon Product

Q: What are the factors affecting the service life of graphite electrode in ultra high power arc furnace?: China's graphite electrode quality standard (YB/T4090-2000) to evaluate the quality of the ultra high power graphite electrode is defined 6 physicochemical indexes, including resistivity, flexural strength, elastic modulus, bulk density and linear expansion coefficient as the quality evaluation index, ash as a reference index.

Q: How to improve the efficiency of graphite electrode milling, please tell me: The technical development of the high-speed machining center lays the foundation for improving the milling efficiency and quality of the graphite electrode, especially for the milling of the small electrode with complicated shape and thin wall. In the EDM mold processing, the graphite electrode needs to be processed by the high-speed machining center (HSM), so the demand for HSM machine tools is also increasing. But for some time, because of the technological developments in hard steel processing, it seems possible to make graphite electrodes an obsolete technology.

Q: Why graphite can be used as conductive material?: Lubricants can not be used in high speed, high temperature, high pressure conditions, and graphite wear-resistant materials can be at the temperature and at a high sliding speed, without lubricating oil work. Many transporting corrosive media devices are widely used, which is made of graphite material piston ring, the sealing ring and the bearing, they are running, without adding lubricating oil, graphite and many metal processing when good lubricant.

Q: The future of graphene: Field of semiconductor materials. Graphene is considered to be an ideal material for replacing silicon. A large number of powerful enterprises have developed graphene semiconductor devices. The Han Guocheng Institute has developed a highly stable n type graphene semiconductor that can be exposed to air for a long time. Graphene silicon optoelectronic hybrid chip developed by Columbia University has broad application prospects in optical interconnection and low power photonic integrated circuit. IBM researchers have developed graphene field effect transistors with cutoff frequencies of up to 100GHz, with frequency performance far superior to the cut-off frequency of the most advanced silicon transistors of the same gate length.

Q: Why should the carbon brush for the trolley be made of graphite?: Graphite has good conductivity

Q: How can hydrogen be produced by electrolysis of sodium hydroxide with graphite as an electrode?: You can think so, since sodium has been reduced, so there is always an atom is oxidized, it can only be oxygen oxidation reaction

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 that affect the electrode wear rate of machine tools?: Effect of peak pulse current on electrode wear. The peak current has a great influence on electrode wear, but the curves are very different due to the different materials of the electrode and the workpiece. In the copper electrode machining steel, general peak current, electrode loss is also large, but also have a great relationship with the pulse width, so in practice, we should choose different peak current of different area according to the data processing technology of power supply and discharge pulse width, can make the processing speed is high, and the electrode loss small.

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: What is the difference between SGL graphite electrode and graphite electrode in general?: Can not say that the more detailed the better, is relative, must be uniform within the range (after all, it is very important to choose the aggregate), such as spectral pure graphite, is not due, he is a lot of technology to producing stains, then burning, and then producing stains, the strength is quite good,
