一、前言现今的铁合金生产电炉,几乎都使用自焙式电极。特别是大型电炉,如果不使用这种形式的电极,电炉的制造和生产是不可能的。可是这种形式的电极的最大缺点是可能发生电极折断事故。如果一旦发生电极折断事故,电炉的全面运行就将停止。特别是超大型电炉,由于采用封闭式,给事故后的复 First, the preface Today’s ferroalloy production furnace, almost all use self-baking electrodes. Especially for large electric furnaces, the manufacture and production of electric furnaces are not possible without the use of this type of electrode. However, the biggest disadvantage of this type of electrode is that an electrode breakage may occur. In the event of an electrode breakage, the full operation of the furnace will cease. Especially large electric furnace, due to the use of closed, to the complex after the accident
