冶炼过程技术经济指标的改善和提高直接与电炉工作制度的研究有关。按现有的工艺,中碳锰铁是以间歇式方法用精炼电炉进行熔炼的。所用的炉料是:1级氧化锰精矿、石灰或石灰石及再制硅锰合金。电炉准备工作结束之后,将大部分硅锰合金撒到电极下方,然后放下电极送电,此后将熔炼一炉用
The improvement and improvement of the technical and economic indexes of the smelting process are directly related to the research on the working system of the electric furnace. According to the existing process, medium carbon ferromanganese is melted by a batch method using a smelting electric furnace. The charge used is: a manganese oxide concentrate, lime or limestone and rework Si-Mn alloy. After the preparation of the electric furnace is completed, most of the silicon-manganese alloy is sprinkled below the electrodes, and then the electrodes are lowered for power transmission, after which a furnace for melting
