电炉炼钢电极所用的圆柱形电极接头,在使用过程中,往往因电极表面氧化严重而导致尾部电极丝扣外露而不得不把剩余短电极敲掉,这就使电极消耗增加。上钢五钢厂采用锥形接头代替圆柱形接头,主要特点是电极根部阴螺纹处壁厚增加近三分之一。这样当电极接头处表面氧化变细,但仍有相当壁厚可以继续支持尾部电极使其不致掉扣脱落,尾部电极也不用敲掉;或者在刚通电时不易震断,从而改善电极使用性能,可以继续冶炼1—2炉钢。但采用锥形接头必须与
In the process of using, the electrode terminals of the steelmaking electrodes of the electric furnace are often exposed by the oxidation of the tail electrode due to the serious oxidation of the electrode surface, and the remaining short electrodes have to be knocked off, which increases the electrode consumption. On the steel five steel cone instead of cylindrical joints, the main feature is the thickness of the root electrode at the root wall thickness increased by nearly one-third. In this way, when the surface of the electrode joint is oxidized and thinned, there is still a considerable wall thickness that can continue to support the tail electrode so that it does not fall off and the tail electrode does not need to be knocked out; or the electrode is not easily broken when just powered on, Can continue to smelt 1-2 furnace steel. However, the use of tapered joints must be
