本文从迁钢2号高炉系统投产运行现状，分析了风温限制环节，并从设备和材料方面考察了其实现高风温的可行性。采用运行参数校核计算1300℃风温，利用仿真软件研究了煤气流量和空气预热温度变化对热风炉流场、温度场的影响，从理论上研究热风炉风温影响因素和存在问题。研究结果表明通过调整热风炉操作参数，可以有效提高风温。通过迁钢2号高炉开展高风温试验，总结分析了实现高风温的具体措施，阐明高风温不仅与热风炉操作紧密关联，而且原燃料、高炉操作等因素直接影响高炉使用高风温。研究结果表明，高风温必须与大喷煤、富氧等技术相结合，才能实现并发挥节能作用。本次高风温试验初步实现最高风温1280℃的目标，上述研究为进一步提高风温试验提供参考。

Limited factor of blast temperature is analyzed as to present state of QIANGANG No.2 blast furnace system put into production, feasibility of high blast temperature is reviewed from facility and material. Blast temperature about 1300℃ is calculated and checked as running parameter, effect of gas flow and air preheated temperature is studied by simulation, blast temperature impacting factor and existing problem of hot blast stove is studied in theory. It shows that blast temperature can be improved in effect by regulating operation parameter of hot blast stove. By high blast temperature test in QIANGANG No.2 blast furnace, practical measure of realizing high blast temperature is summed up and analyzed, it shows that high blast temperature is related with stove operation, and factor of material-fuel and operation affects using high blast temperature in blast furnace. It shows that high blast temperature should be combined with technology such as large coal injection and enriched-oxygen, so it will be realized and bring the effect of energy-saving. The aim of high blast temperature to 1280℃ is realized by this test of high blast temperature, the study above will offer reference for improve blast temperature more.
