摘　　要：以SEBUKU铁矿和硅镁型镍红土矿为原料,采用还原窑还原,研究混合物料还原焙烧的最佳温度及配碳系数对还原镍合金和排放烟气的影响.研究表明:还原时间的是影响金属镍、金属铁的关键因素,合适的配碳量是还原镍铁合金的重要条件.配碳量的多少也直接影响着排放烟气的成分含量.Using SEBUKU iron ore and silicon-magnesium-type nickel-laterite as raw materials,the effects of the optimum temperature and carbon ratio on the reduction and roasting of the mixture on the reduction of nickel alloy and the emission of flue gas were studied in a reduction kiln.The results show that the reduction time is the key factor affecting nickel and iron,and the proper amount of carbon is an important condition for the reduction of ni-fe alloy.The amount of carbon has a direct effect on the composition of the flue gas.
