Q:What are the structures of pyrolytic graphite electrodes? What are their properties and applications? We hope that some details will not be found

The high purity graphite component is put into the furnace, and nitrogen and methane are produced under vacuum high temperature. Then graphite is shown to produce 10% coating.

Q:After vacuum melting of quartz crucible, there are three graphite electrode rods. What's the adjustment?

Or did you adjust the electrode when it was installed? There are two electrode distance, two away, causing melting after different lengths.

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

The national standard normal power graphite electrode graphite electrode: the standard name standard classification number Q51 Standard No. YB/T 4088-2000 for YB/T 4088-2000 YB/T 4088-1992 2000/12/1, instead of the execution time of 0:00:00 release time 2000/7/26 0:00:00 adoption situation

Q:What about graphite electrodes for steel mills?

For steel and iron alloys, graphite electrodes are used, when powerful currents pass through electrodes into the melting zone of the electric furnace to produce an arcThe electric energy is converted into heat energy, and the temperature is increased to about 2000 degrees, so as to achieve the purpose of smelting or reaction. In addition, the electrolytic goldWhen the magnesium, aluminium and sodium are used, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as the burnerConductive material.

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:How does graphite produce solar cells?

Gerrit J said: "despite the modifications, but the inherent nature of graphene remains unchanged, is a significant advantage of composite materials."

Q:How can I electroplate iron? I would like to use graphite as an electrode. Iron is plated on graphite with iron solution, so it can be processed into iron parts. I wonder if it can be done

Iron plating can be, with 2 valence iron, but on the graphite joint force is good, it is difficult to say, electroplating is bad, peeling is also common. Relatively speaking, iron parts on nickel plating is relatively simple, also more applicable

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

Because in the process of electrolysis of water in cathode electron generated hydroxyl, the alkaline solution increased. But with the hydroxyl reaction of sodium carbonate and sodium bicarbonate, carbonate and calcium ions exist at the same time, must produce the precipitation of calcium carbonate, the ion in the solution is reduced, thereby conductive resistance increases. Thus weakened over time current cannot be raised

Q:Specification for graphite electrodes commonly used in steel works

The variety and specifications of graphite electrodes used in modern EAF steelmaking are mainly determined by the technical parameters of the steelmaking furnace. 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.
