介绍缅甸达贡山镍矿冶炼高品位镍铁的工艺改进和生产实践。通过取消石灰石熔剂的配入、将镍品位由25%提高到35%、焙砂温度提高到700℃以上、强化系统原料控制等措施,有效解决了电炉长期存在的泡沫渣和翻料等工艺问题,产能达到设计产能108%以上,各项消耗指标大幅下降。
Abstract：Technical improvement and plant practice of production of high grade Ni-Fe alloy from nickel laterite in Myanmar Dagaung Taung were introduced.With measures including canceling limestone addition,improving nickel grade from 25% to 35%,raising calcine temperature to 700 ℃ above,and strengthening raw material control etc,long term technical problem of foaming slag in electric furnace is solved effectively,production capacity is 108% of the designed capacity,and consumption index drops sharply.
