摘要
昆铜隧道窑生产的直接还原铁存在产品质量不稳定的问题，影响了转炉应用隧道窑直接还原铁的工业性试验。经过试验研究，针对直接还原铁的金属化率和S含量的波动问题，提出了适宜的工艺参数和改善直接还原铁质量的措施。
The problem of the unstable quality of DRI effected industrial application test of DRI on the convener. After the test, the measures of the process parameters and improvement in quality of DRI were proposed to solve the fluctuation of the metallization rate and [ S ] of DRI.
