摘    要: 基于将氧化钼代替钼铁加入AOD炉中生产316L不锈钢的新思路,分析了AOD炉熔池中主要元素还原氧化钼的热力学和氧化钼还原机理并推导出其还原速率公式,讨论了AOD炉冶炼过程中氧化钼加入方式,介绍了将氧化钼置于AOD炉中冶炼316L不锈钢钢液的工业实践。结果表明:氧化钼在AOD中有很好的还原条件,在加入AOD炉后的半小时之内能够完全还原;氧化钼应该以复合球团(氧化钼、还原剂和抑制剂混合造球)的形式加入AOD炉中,保证冶炼正常进行的同时最大限度提高钼资源的利用效率。实际生产状况良好,达到了预期的效果。

关 键 词:氧化钼  还原  AOD炉  316L不锈钢

Abstract:A new smelting method was raised that molybdenum trioxide instead of ferromoly, was added to AOD furnace for 316L stainless steel. Based on the new method, thermodynamics of reduction of molybdenum trioxide was analyzed by the main elements in the AOD bath,the reduction mechanism of MoO3 was discussed and the formula of its reduction rate was deduced. In addition, it was involved that how the moly-oxide was put into the AOD furnace. There was a brief account of industrial practice in which moly-oxide was used for the refining of 316L stainless in AOD furnace. It shows that on one hand, the moly-oxide AOD furnace possesses excellent condition for the reduction of moly-oxide, for which reason it will be completely reduced in half an hour, on the other hand, it is better to utilize moly-oxide composite pellet containing moly-oxide, reductant and inhibitor for steady and safe refining process and the best use of moly- resource.
