Large Size Carbon Electrode CNBM China 500--700

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: What are the skills of hardfacing process for wear-resistant alloy powder blocks?: The power supply adopts the DC arc welding machine with steep drop characteristic, adopts the positive connection method, the electrode is negative, and the electrode is a high strength spectrum pure graphite rod,

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

Q: What is the reason that the current cannot be increased when the graphite electrode is used for anode electrolysis?Add calcium chloride and sodium bicarbonate into electrolytic water: The reason is that the resistance increases continuously, the number of ions is limited, and the conductivity is limited

Q: Does the silicon carbide heat plant require a fine structure graphite electrode? What kind of graphite products do you need?: Silicon carbide graphite is very famous for its high hardness and wear resistance. It is generally used in high wear resistance machinery industry and high wear resistant sealing industry.

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: Is the anode of electrolytic water suitable for ordinary titanium wires?: Graphite firstFirst of all, the titanium electrode is usually not pure titanium, it should be titanium with a metal oxide coating. Secondly, the advantages of the titanium electrode is mainly to save electricity, the corrosion resistance of carbon is much stronger than that of industrial production, if the meaning is relatively large, but it is still in laboratory experiments, electrolysis of water, not what meaning.

Q: The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.: A galvanic cell is a device that converts chemical energy into electrical energy. Electron transfer not by oxidizing and reducing agents to complete the effective collision between, but the reducing agent loss electron oxidation reaction occurs in the anode, the electron transport to the anode through the external circuit, the oxidant to the anode electron reduction reaction, so as to complete the transfer of reductant and oxidant electrons.

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.
