摘　　要：针对烧结机的漏风问题,分析了其漏风原因,找出了相应的漏风环节,在此基础上介绍了中冶长天开发的低漏风综合密封技术—负压吸附式端部密封技术、新型滑道密封技术、烧结机台车密封技术、气动双层卸灰阀技术等。并采用烧结机台车空载静态密封测试与烧结机台车额定负载动态测试相结合检测烧结机漏风率的方法对实施低漏风综合密封技术的湛江烧结机进行了漏风检测,烧结机本体漏风率为17.59%,与普通烧结机相比,漏风率下降比例近50%,符合国家节能减排、降本增效的产业化政策。In view of air leakage problem of the sintering machine, the causes of air leakage were analyzed, and the corresponding air leakage parts were found, and based on this, the integrated low leakage sealing technologies devdoped by Zhongye Changtian were introduced, including the negative pressure adsorption end sealing technology, the new type slide sealing technology, the pallet sealing technology of sinter machine and the pneumatic double-act dust dump valve technology etc. The method of detecting the air leakage rate of the sintering machine in combination with the static load test of the sintering machine pallet and the dynamic test of the rated load of the sintering machine pallet was used to test the air leakage rate of the Zhanjiang sinter machine, and the air leakage rate of the sinter machine was 17.59%. Compared with the conventional sinter machine, the air leakage rate of sintering machine has dropped by nearly 50 %, which is in line with the national industrial policy of energy conservation, emission reduction and cost reduction.
