摘要: 利用碳热还原方法,开展了高炉瓦斯泥焙烧脱锌实验研究。研究结果表明,碳热还原焙烧高炉瓦斯泥可有效脱除高炉瓦斯泥中的锌。最佳工艺条件为:焙烧温度为1 423 K,焙烧时间为180 min,物料粒径为9.5~10.5 mm。在最佳工艺条件下,高炉瓦斯泥脱锌率达99.2%,焙烧剩余渣中锌质量分数低于0.15%,可返回高炉使用。

关键词: 高炉瓦斯泥, 碳热还原, 脱锌率

Abstract: The dezincification of blast furnace flue slime was investigated by carbothermal reduction method.Researching results showed that zinc in the blast furnace flue slime could be effectively removed by carbothermal reduction method.Under the optimum conditions of sintering temperature of 1 423 K,sintering time of 180 min,and material′s particle size at 9.5~10.5 mm,dezincification rate of the blast furnace flue slime could be as high as 99.2%,and zinc content of the sintering remaining slag was less than 0.15%. The remaining slag could be returned to the blast furnace.

Key words: blast furnace flue slime, carbothermal reduction method, dezincification rate
