Carbon electrode are applied for the production of silicon metal as they have peculiar characteristics.
Carbon electrode is used as electric current conductors in electric furnaces where silicon metal, elemental phosphorus or -to a small extent -other specialties are produced.
Requirements for carbon electrode are:
- Good electrical conductivity: in order to withstand the high current density required by the metallurgical process.
- Good thermal conductivity: to minimize the temperature differences inside the electrodes when in use and, consequently to reduce internal stresses.
- Good mechanical strength: to withstand the stresses when in use.
- High level of chemical purity: to avoid polluting the end product.
- Reliable joint: to ensure current flow continuity in the electrode column.
- Easy mounting: to facilitate and speed up operations for the lengthening of the electrode column.
- Accurate machining on the external surface on the joints: to avoid problems when the joint passes through the holding clamps and the contact shoes and to facilitate the current flow from one electrode to the following one.
Peculiar characteristics of carbon electrodes for silicon metal production are:
- Carry large amounts of electrical current.
- Withstand very high temperatures.
- Keeping good mechanical properties under above-described circumstances.
What are the benefits of using the carbon electrode?
Day by day there exist so many industries that move
started to use the carbon electrode because it
remains the most utilized in several kinds of machinery. Once you realize the
worth of it surely you will never choose another one at any time. Still, there
is nothing can replace the worth of it because it is the most wanted one for
all the people.
Highly preferred one forever
It implies essentially utilized for the electrolysis
method plus it remains to have a high melting point also. If you are having any
doubt to use it you will clarify it from the internet. Now it is available at a
very low cost also that is the main reason for it becomes the stunning one than
the other. It is available in two for which denotes insert electrodes including
active electrodes.
It holds the widely utilized one for many types of machinery. Hereafter you no need to worry about where you can get better results about to choose the carbon electrode. Now you will have a clear idea about it so try to share the merits of it with everyone. You can also suggest who needs it plus it will be more helpful for them.
