矿热炉的自焙电极应满足两个基本要求:焦化后的电极烧结体应具有很高的质量;焦化带的位置应稳定。研究结果确定:电极烧结过程基本上以电极内的焦耳热来保证进行;耗用于烧结过程的热量在电极内的总热平衡中不超过10%; The self-baking electrode of the submerged arc furnace should meet two basic requirements: the sintered body of the electrode after coking should have a very high quality; the position of the coking belt should be stable. The results of the study confirm that the electrode sintering process is basically guaranteed by the Joule heat in the electrode; the heat consumed in the sintering process does not exceed 10% of the total heat balance in the electrode;
