ferronickel use electrode paste
The purpose and characteristics of ferronickel use electrode paste
In the process of producing calcium carbide, ferrosilicon, ferromanganese and other ferroalloys, the smelting temperature needs to be increased. This can only meet the requirements of production by inputting a strong current through a special electrode into the furnace.
To make the electrode work normally at the very high temperature in the electric arc furnace, the electrode itself must have good electrical conductivity, oxidation resistance and thermal shock resistance. Only ferronickel use electrode paste produced with carbon raw materials can be capable of 3000 degrees. The above stringent smelting requirements under continuous arc high temperature. Therefore, ferronickel use electrode paste occupies a very important position in the above mine thermoelectric furnaces, so it is called the “heart” of this type of electric furnace.
Ferronickel use electrode paste is a kind of “continuous self-baking electrode” in terms of its use method and properties. During use, the outer layer of the continuous self-baking electrode is made of steel plate with a thickness of 1-2 mm. , Ferronickel use electrode paste is regularly added to the cylinder. With the time of production, ferronickel use electrode paste is gradually softened—melted—baked. During baking, a large amount of volatile matter is released, and when it enters the conductive clip part of the electrode , Due to the effect of high temperature from semi-coking to complete coking, it becomes a conductive carbon electrode, and the cylinder made of steel plate is melted into the charge. By the various heat of the electric furnace itself, ferronickel use electrode paste is baked into a conductive electrode, so it is called a self-baking electrode.
