摘　　要：旨在镍铁渣回收利用。本文探究了从镍铁渣中提取硅铁合金的可行性实验。通过用C作还原剂,在不同温度、真空度和不同添加剂的条件下,对镍铁渣进行还原反应得到硅、铁元素。结果表明Fe2O3还原率和Si元素的收得率随着反应温度的升高而升高,随着真空度的升高而升高,在一定范围内随着添加剂添加量的增加而升高。For the recycling of ferronickel slag,in this paper,the feasibility experiment of extracting ferronickel alloy from ferronickel slag was explored.By using C as the reducing agent,the reduction reaction of ferronickel slag was carried out to obtain silicon and iron elements under the conditions of different temperatures,vacuum degrees and different additives.The results show that the reduction rate of Fe2 O3 and the yield of elemental Si increase with the increase of the reaction temperature,with the increase of the vacuum degree,and in a certain range with the increase of the additive addition.
