烧结机抽风系统漏风原因分析及对策

Cause Analysis and Solution Strategy of Air-leakage of the Air-suction System of Sintering Machine

通过对265 m2烧结机抽风系统漏风点逐一排查,找出烧结机台车车体间、风箱伸缩节等5处漏风点,采取了改造烧结机固定滑道润滑系统、利用年修治理烧结机的跑偏问题、改造双层卸灰阀等措施,使系统漏风得到治理,烧结机利用系数提高了0.06 t/(m2.h),产品合格率提高到93.63%,直接经济效益近千万元。

Through a comprehensive study of the air suction system on a 265 m^2-sintering machine, 5 air- leakage places were found, includ- ing the alr-leakage in the trolley system and wind box branch pipe. To solve this problem, we came up with some solution strategies, modifying lubrication system, controlling of sintering machine running deviation by maintenance and reforming the double dust valve etc. Solution on the air-leakage makes the utilization coefficient of sintering machine increased by 0.06 t/（m^2. h）, qualified rate of production reached 93.63%, which improved economical benefits of about 10 million Yuan.
