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?: What happens is oxygen etching negative pole: Fe-2e-=Fe2+ positive electrode: O2+2H2O+4e-=4OH-, of course, the current is produced.

Q:Electrolytic water solution, two electrodes are graphite electrode, the negative electrode can produce large amounts of hydrogen, the anode does not produce half of oxygen, and only a small amount of it?: The oxygen will react with the graphite and the gas will dissolve.The iron has been oxidized.

Q:Graphite graphite graphite graphite electrode what is the use?: Of course all conductive graphite gray, conductive powder is used for professional conductive, the conductivity is different, in order to achieve its electrical resistance value, the graphite powder of different particle by the ratio to reach the ideal value of resistance. Graphite powder is pure graphite powder, requirements of mesh consistent, high purity.

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 are the factors affecting the service life of graphite electrode in ultra high power arc furnace?: The ultra high power graphite electrodes produced in China are 300mm, 350mm, 400mm, 450mm, 550mm, 600mm, 650mm, 500mm and 700mm, with lengths of 1600mm, 1800mm, 2000mm, 2200mm, 2400mm and 2700mm.

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:What are the factors that affect the electrode wear rate of machine tools?: Effect of processing voltage on electrode wear. The processing voltage is the average voltage between the discharge time and the gap. When the voltage is lower than the power supply voltage (voltage) 25%, electrode loss will increase, which is due to the electrode and the workpiece is too close, the discharge column energy is too large, the electrodes generate heat radiation is too strong, at the same time, there are a large number of continuous arc discharge. But the working voltage is too high (partial load processing), bad conditions of thermal effect in the gap, is not conducive to the adsorption of copper electrode of carbon graphite, destroy the covering effect. Similarly, the electrode loss increase, therefore, corresponding to different processing standards should be selected to adjust the discharging gap voltage.

Q:How about graphite electrode high-temperature oxidation resistant coating?: The utilization ratio of graphite energy can reach more than 95%. Many kinds of antioxidant paint, it is recommended to directly find their technicians, you can give professional advice, according to the actual situation, the reasonable use of high-temperature oxidation resistant paint.

Q:Graphite can be used in acid towers in chemical plants because of graphite: Ultra high power graphite electrode. A graphite electrode that allows current densities greater than 25A/ cm 2 is allowed. Mainly used in ultra high power steelmaking arc furnace

Q:Why use platinum ferroalloy instead of iron as electrode?: Silica (Silica) is widely used in paint, ink, plastic, rubber and cosmetics, are often added to increase the performance of silica, such as oil absorption, extinction, strengthen the mechanical... Etc., and can reduce the cost of...

Graphite electrodes are widely used in electric arc furnace and ladle refining furnace for steel making; and used in electric smelting furnace for producing ferroalloys, yellow phosphorus, corundum . The products are well sold to more than 30 countries and regions including Europe, America, Japan, Brazil, South Africa, Australia, the Middle East and so on , and enjoy good reputation. We sincerely welcome domestic and overseas customers to our company for cooperation.
