With the continuous improvement of metallurgical technology, the application field of metallurgical products is expanding. At present, China’s basic industry is developing rapidly, especially the development of electrode paste.
Electrode paste is a conductive material used for electric furnace equipment such as ferroalloy furnace and carbide furnace. It can withstand high temperature and has a small coefficient of thermal expansion. And has a relatively small resistance coefficient so that the loss of electric energy can be reduced. It has a small porosity so that the electrode in the heated state can be oxidized slowly. With high mechanical strength, the electrode will not be broken due to the influence of mechanical and electrical loads.
The current is input into the furnace through the electrode to generate an arc for smelting. The electrode plays a very important role in the whole electric furnace. Without it, the electric furnace cannot produce its role. To make the electrode work normally under the temperature generated by the arc, it needs to have a high degree of oxidation resistance and conductivity. This electrode can only be made of carbon material and has this excellent property. Because the carbon electrode can withstand arc temperatures up to 3500. D egree.
