介绍了在莱钢集团板带厂1 500 mm热连轧线开发的热轧工艺润滑系统组成及良好的应用效果。应用热轧工艺润滑后,可以降低轧辊磨损20%～40%,轧制力降低10%～20%,轧机主电机电流亦相应降低,实现节能降耗,效益显著;同时改善带钢表面质量,效果明显。另外本系统具有创新点:国内唯一采用喷嘴小孔径技术,吨钢油耗量指标国内领先;在控制系统中设置了独有的喷嘴清洗防堵塞技术。
The composition of the hot rolling process lubrication system developed on the 1 500 mm hot rolling line of the strip plant of Laiwu Steel Group Co., Ltd. and its good application effects are introduced. After the hot rolling process is applied, the wear of the roll can be reduced by 20-40%, the rolling force can be reduced by 10-20%, the main motor current of the rolling mill can be reduced correspondingly to realize energy saving and consumption reduction with significant benefits; at the same time, the strip surface quality, The effect is obvious. In addition the system has the innovation: the only nozzle using a small aperture technology, tons of steel fuel consumption indicators leading the country in the control system set a unique nozzle cleaning anti-jamming technology.
