Q: Is graphite electrode good for foreign trade?: Profits can be made for foreign trade. Even if you produce it yourself. Traders take big head. Own production. It's hard for you to play. If you have a client, we can work together

Q: Why use platinum ferroalloy instead of iron as electrode?: Its surface properties must comply with the characteristics of the additives so that they can be dispersed evenly.

Q: Where is the graphite electrode scrap?: Atoms, ions, and electrons collide with each other in strong oscillatory motion to produce more electrons and ions.

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: The original battery is not necessary to form the electrode potential? Why can we use graphite as electrode only? No potential difference.: Indeed, the original battery electrode potential using two different electrodes, produce potential difference, so that the electron flow generated current. Graphite is used as an electrode because of its excellent electrical conductivity and stability

Q: The production of one ton of steel required graphite electrode: Can not generally say, a ton of steel production consumes much of graphite electrode.

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: What does graphite electrode GSK mean?: Graphite board material is GSK, GSK refers to model specifications

Q: What are pyrolytic graphite electrodes used for?: (1) the processing speed is faster: normally, the mechanical processing speed of graphite can be 2~5 times faster than copper, while the discharge processing speed is 2~3 times faster than copper;More material is not easily deformed: obvious advantages in the processing of thin electrodes; copper softening point at about 1000 degrees, easily deformed by heat; graphite sublimation temperature is 3650 degrees; the thermal expansion coefficient of copper is only 1/30.

Q: Graphite is made of high-strength graphite, it is a kind of graphite grade specification.: Most of the graphite electrodes are cylindrical, but also have square and multi ribbed shapes. Graphite blank refers to the firing of raw materials without processing graphite.
