摘　　要：某镍冶炼厂采用侧吹炉将二次镍精矿、镍残极熔炼生产镍阳极板试验。本次试验形成了一套侧吹工艺技术,产出镍阳极板Ni含量>70%,S含量<21%,Ni回收率99%、Cu回收率99%,并实现连续进料、连续吹炼,减轻了物料进入炉内的频繁翻料现象。该试验不仅在镍产能方面全面提升,更在镍冶炼工艺技术路线上进行革命性突破。A nickel smelter was tested to produce nickel anode plates by smelting secondary nickel concentrate and nickel residue in a side-blown furnace.This test formed a set of side-blowing technology,the output of nickel anode plate Ni content>70%,S content<21%,Ni recovery rate of 99%,Cu recovery rate of 99%,and to achieve continuous feeding,continuous blowing,reduce the material into the furnace frequent turnover phenomenon.The test not only comprehensively improves the nickel production capacity,but also makes a revolutionary breakthrough in the nickel smelting process technology route.
