Electrode paste: It is a conductive material used for electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. Electrode paste, also known as self baking electrode, relies on the heat inside the ore furnace to complete the baking process. Therefore, matching the consumption rate of the electrode with the baking rate is the key to the use of electrode paste. Due to the development of ore furnace technology, it is gradually moving towards larger and more enclosed directions. During the baking process, the electrode can only reduce the amount of conductive and radiative heat obtained from the open furnace type in the past, which is only conductive heat. Therefore, the heat obtained by the electrode from the furnace is greatly reduced. This requires improving the sintering performance of the electrode paste to make up for this deficiency. Electrode paste can withstand high temperatures and has a low coefficient of thermal expansion. Having a relatively small resistance coefficient can reduce energy loss. Having a smaller porosity can slow down the oxidation of electrodes in a heated state. Having high mechanical strength is essential to prevent electrode breakage due to the influence of mechanical and electrical loads.
