一、前言如何减少漏风.是当前设计烧结设备和改造烧结设备都必须考虑的重要问题之一。目前国内烧结机总漏风率一般在40～60％,有的甚至高达70％,烧结机风机的抽风量仅仅利用丁50％左右。另外也影响烧结厚料层操作的推广应用,所以减少烧结机的漏风率是增产节能最重要最有效的途径之一。根据目前烧结设备的特点及我厂实际,我们选定 I. Preface How to reduce the air leakage is one of the important issues that must be considered in the current design of sintering equipment and renovation of sintering equipment. At present, the total domestic air leakage rate sintering machine is generally 40 to 60%, and some even up to 70%, the sintering machine blower exhaust capacity of only about 50%. In addition it also affects the popularization and application of the operation of sintering thick material layer, so to reduce the air leakage rate of the sintering machine is one of the most important and effective ways to increase energy efficiency. According to the characteristics of the current sintering equipment and our actual plant, we selected
