摘　　要：柳钢烧结工艺长期受混料圆筒结料厚、清料难困扰,经常因圆筒结料造成非计划停机进行清理。技术人员针对该问题,提出气液复合多点分段式加水、圆筒运行电流结料预警和高压喷吹在线清料3项优化措施和改造方案,并将3者有机结合,从而实现在线清料。投产使用后,有效解决圆筒结料现象,烧结工艺参数得到优化,为保障烧结工艺高效、连续、稳定运行提供一定技术指导。Sintering process of Liugang has been plagued by thicker mixing cylinders and difficult cleaning for a long time.Unplanned downtime for cleaning is often caused by serious sticky material problems in the cylinder.In response to this problem,technicians put forward three optimization measures and transformation schemes which were gas-liquid composite multi-point segmented water addition,cylinder running current accumulation warning and high-pressure injection online cleaning,and organically combined the three to achieve online cleaning.After putting into production,it improved the phenomenon of cylindrical material formation effectively,optimized the sintering process parameters,and provided certain technical guidance for ensuring the efficient,continuous and stable operation of sintering process.
