从迁钢2号高炉系统投产运行现状,分析了风温限制环节,从热风炉、热风管道和高炉接受高风温等全面考察了其实现高风温的可行性。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1 280℃的目标,上述研究为进一步提高风温试验提供参考。
Based on the operation status of blast furnace No.2 blast furnace system, the article analyzes the limitation of air temperature, and investigates the feasibility of achieving high wind temperature from hot blast stove, hot blast pipe and blast furnace. Through high temperature test of No.2 blast furnace in Qiangyang Iron and Steel Co., Ltd., concrete measures to achieve high wind temperature are summarized and analyzed. It is pointed out that high wind temperature is not only closely related to operation of hot blast stove, but also factors such as raw fuel and blast furnace operation directly affect high blast temperature . The results show that the high wind temperature must be combined with technologies such as large coal injection, oxygen enrichment and so on to realize and exert energy saving effect. The high wind temperature test initially achieved the highest temperature of 1280 ℃ goal, the above study to further improve the wind temperature test provide a reference.
