Product Description

Graphite Electrode is mainly usde for steel-making in electric arc furnace, Ore-smelting Electric furnace and electric resistance furnace. Graphite electrode conduct electric current into the furnace. Electric current produces arc in the smelting

district in the electric furnace, when the temperature increase to about 2000 degree centigrade, raw material begin smelting and products manufactured.A series of graphite electrode is applicable to the common furnace and high power furnace with high pressure and short arc.

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: 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: What's the use of carbon?: High power graphite electrode. Allows the use of current density of 18 ~ 25A/ cm 2 graphite electrode, mainly used in steel-making high power arc furnace

Q: Can graphite be used as an electrode for electrolysis of silver in silver nitrate?: Xiaoyi Liyang said the principle is correct, but can get silver? I think we can solve the problem if we take proper measures to get the silver elements, such as separating the anode and the cathode from the salt water!

Q: What is the application of wire cutting with graphite electrode?: Greatly shorten the preparatory time of mechanical processing, and improve the level of automation of the whole process of machining, and also enhance the ability of the manufacturing system to adapt to changes in production conditions.

Q: Can Naiduo high temperature graphite: The reinforced graphite gasket is made of flexible graphite tape or flexible graphite and is molded into ring products of different sizes. Suitable for hot water, high temperature, high pressure steam, heat exchange liquid, nitrogen gas, organic solvent, hydrocarbon, low temperature liquid and other medium. Used in compressors, machines, pumps, valves, chemical instruments, instruments, etc..

Q: How should carbon deposits be treated?: At certain temperature, can make alloy and carbon can react in the engine surface coated with a layer of graphene film, graphene nano particles can fill the pores, wear scratches, on the friction surface repair function.

Q: Carbon graphite electrode and what is the difference?: The difference between graphite electrode and carbon is mainly composed of graphite manufacturing, the latter for carbon materials,

Q: 800KVA and 12500 EAF transformer data graphite electrode furnace.: Graphite project: Project Description: steel furnace and iron smelting furnace, ferrosilicon smelting, electrolytic aluminum and so on, all use large surface graphite electrode.

Q: Graphite is made of high-strength graphite, it is a kind of graphite grade specification.: The difference is: the graphite bar may be machined graphite electrode materials may be insulated with material of graphite. Graphite electrode is an electrode product to guide the processing of graphite material with good electrical properties. Bars are usually cylindrical.
