electrode paste is a conductive material for electric furnace equipment such as ferroalloy furnace and calcium carbide furnace. The electrode paste is also called self-baking electrode, which is roasted by the heat in the ore furnace. Therefore, matching the electrode consumption rate with the roasting rate is the key to the use of electrode paste. Due to the development of ore furnace technology, the electrode paste is gradually developing towards large-scale and closed direction. In the process of electrode roasting, the most conductive heat and radiant heat obtained by the previous open furnace type are only conductive heat, so the heat obtained by the electrode from the furnace is greatly reduced, which requires improving the sintering performance of electrode paste to make up for this deficiency.
electrode paste can withstand high temperature and has low thermal expansion coefficient. With relatively small resistivity, can reduce the loss of electric energy. Low porosity allows slow oxidation of the heated electrode. With high mechanical strength, the electrode will not be broken due to mechanical and electrical loads.
Current is through the electrode input furnace arc smelting, the electrode in the entire furnace is a very important position, without it, the furnace can not produce effect. For an electrode to operate at the temperatures generated by the arc, it must have a high degree of oxidation resistance and electrical conductivity, which can only be achieved by electrodes made of carbon materials, which can withstand arc temperatures up to 3500℃ and only slow oxidation.
