摘　　要：对宣钢1号高炉风温持续降低的原因进行了分析,通过降低煤气含尘、采用自动烧炉技术、提高高炉富氧率、换热器定期清灰、规范化职工操作、强化设备点检等一系列措施,遏制住了风温持续下滑趋势,并且风温水平逐步提高,为高炉长期稳定顺行和节焦降耗奠定了基础。This paper analyzed the reasons that blast temperature continuing to falling, through reducing the dust content in gas, adopting the measures of hot stove automatic burning, improving the oxygen enrichment percentage,heat exchanger cleaning periodically, pushing staff standard operating,strengthening equipment inspection, and so on.The blast temperature downturn is curbed, and blast temperature is being raised gradually, laying the foundation for the smooth operation state and section code consumption on BF.
