electrolysis using graphite electrodes
Electrode paste and waste electrolysis using graphite electrodes What are the components and differences?
Electrode paste is a conductive material supplied to electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. It can withstand high temperatures and has a small coefficient of thermal expansion. It has a relatively small resistivity, which can reduce the loss of electrical energy. With a small porosity, the electrode in the heated state can be oxidized slowly. The high mechanical strength prevents the electrode from breaking due to the influence of mechanical and electrical loads.
The electric current is smelted by the electric arc generated in the furnace through the electrode input, the electrode occupies a very important position in the entire electric furnace, without it, the electric furnace cannot produce any effect. To make the electrode work normally at the temperature generated by the arc, it needs to have a high degree of oxidation resistance and conductivity. This is only the electrode made of carbon material, because the carbon electrode can withstand the arc temperature of 3500 ℃ Only slowly oxidize.
