| 摘 要： | 对某炼铝企业的赤泥进行了物相分析和物化性能研究,并针对该物料特点提出了还原熔炼生铁的工艺。考察了温度、焦比、氧化钙加入量三因素对还原炼铁渣型的影响。在焦比20%、温度1500℃、C]/A]为2.0左右的优化条件下,熔炼出的生铁符合炼钢用的生铁国标(GB717-82)。对熔渣进行了碳酸钠法浸出回收铝试验研究,改善了赤泥熔炼生铁的经济性。

| Abstract: | The phase analysis and physicochemical feature of red mud from a aluminum factory are studied,According to the feature of material,the technology of reduction smelting pig iron is invented.The phase of iron slag is investigated under temperature,coke ratio and dosage of CaO.The best conditions are 20%(coke ratio),1500℃ and 2.0().At the best condition,the pig iron is adapt to the standard(GB717-82).The aluminum is recovered from iron slag by alkali leaching,which can improve the economical efficiency of smelting pig iron by red mud. |
