摘　　要：在“以风为纲”的铁矿烧结过程中,漏风对烧结生产带来严重的不利影响,如增大主抽风机的功耗、降低烧结生产质量和产量、加速设备失效、加大环保治理难度等。从分析烧结机漏风的部位出发,介绍了烧结机漏风率测定方法,指出应将静态流量法和烟气成分分析法相结合来综合评估烧结系统的漏风率;综合整理和分析了烧结机漏风治理关键技术,重点分析了以负压吸附式端部密封技术为代表的烧结机综合密封技术;总结归纳了国内外钢铁企业针对烧结机漏风所采取的有效措施及效果,为烧结机漏风治理提供参考和借鉴。In the sintering process of iron ore with"wind as the key link",air leakage has a serious adverse effect on sintering production,such as increasing the power consumption of main exhaust fan,reducing the quality and output of sintering production,accelerating equipment failure,and increasing the difficulty of environmental protection.Based on the analysis of air leakage positions for sintering machine,the detection method of air leakage rate for sintering machine is introduced.It is pointed out that the air leakage rate of sintering system should be comprehensively evaluated by combining static flow method with flue gas composition analysis method.The key technologies of air leakage control of sintering machine are comprehensively sorted out and analyzed,and the comprehensive sealing technology of sintering machine represented by negative pressure adsorption end sealing technology is emphatically analyzed.The effective measures and effects taken by iron and steel enterprises at home and abroad for air leakage of sintering machine are summarized,which provide reference for air leakage control of sintering machine.
