摘　　要：烧结过程中,蓖条粘结是引起生产波动、产质量下降的重要因素.针对2013年2～4月京唐烧结机台车蓖条粘结严重的问题,比较了不同粘结程度蓖条粘结物的成分与物相组成,发现KCl是引起蓖条粘结的重要表征;同时认为,烧结制粒效果变差、FeO升高等也是造成蓖条粘结的原因.采取了提高铺底料粒度和厚度、降低含钾、氯元素高的原料配比、烧结制粒优化等攻关措施,使蓖条粘结的现象大幅度减少.In sintering the adhesion on grates is an important factor to cause production unsteady, output de- creased and quality worse. For the serious adhesion during Feb. to Apr. of 2013, the composition and phase components of adhesion materials with different adhesive extent are compared, and KC1 is found to be an im- portant factor to cause the adhesion; at the same time it is considered that bad sintering and pelletizing effect and increased FeO content are also the reason. With the measures are adopted： increasing bottom material particle size and spreading thickness, reducing proportion of potassium - bearing and chlorine - bearing raw material, optimizing sintering pelletizing, the adhesion is greatly decreased.
