摘　　要：针对马鞍山钢铁股份有限公司300t顶底复合吹炼转炉原工艺存在的问题,通过对氧枪系统管道压力损失测定,喷头参数分析及实验室底吹系统水模试验的研究,借鉴同类转炉相关经验,对氧枪喷头、吹炼枪位、加料及底吹工艺进行了优化。生产实践表明,其对稳定转炉操作,改善终渣状况、减少终点钢水氧含量、提高转炉炼钢过程和终点控制水平等方面均有不同程度的效果。In light of the problems existing in the original process of 300 t top-bottom combined blown converters in Ma＇anshan Iron and Steel Co. , Ltd. , the nozzles of the oxygen lance, position of the blowing lance, materials charging and bottom blowing process are optimized by way of measurement on the pressure loss of the tube in the oxygen lance system, analysis on the parameters of the nozzles of the oxygen lance and water modeling of the blowing system in the laboratory as well as learning from the experiences concerned. Production practice shows that positive results have been achieved to some extent in the aspects of stabilization of the converter operation, improvement in the final slag, reduction of the end-point oxygen content in the hot metal and improve- ment in the control level of in-process and end-point control of steel-making.
