The Tips of Graphite Electrodes

Taking from a pile, subject to a support conductor of the current, copper tube and at a reasonable distance a plastic handle, Graphite Electrode is nothing more than a sharp graphite rod. What melts the metal is the graphite tip that shortly turns to bright white. What is heated by the current is graphite, not metal, because graphite electrode has a much greater resistance and dissipates more of the power. It's common to see that the tips of graphite electrodes are sharp. There are two main reasons:

 

Firstly, the finer point of contact between the material and the tip has more resistance to current and more temperature reach. If it is too thick, heat is transmitted easily from the tip to the soldering iron and a large part it dissipates without reaching the necessary temperature. The scrap iron only works if it concentrates most of the power at the point to be soldered. The second reason is that it's easy to attach to the machine or changing to the new one. With one side convexity and the other side concavity, two of rods can be attached to each other easily with the small nipple inside. This system allows changing the electrodes quickly, adjusting their position, and providing a good electrical contact in use as well.

 

For providing with better connection with graphite electrodes and furnaces, Xinhui Carbon has strict quality monitoring on the quality of nipples as it plays the crucial role in the electric current passing through the graphite electrodes. Our main plant is located in the city of Handan, the heart of Northeast China. Not only one of the best sellers domestically but also exported to different countries with excellent product quality.
