轧辊轴承专用脂在钢厂中的应用

Application of Roller Bearing Special Grease in Steel Mill

文章主要讲述了一种具有优良高温性能、高负荷以及良好抗水性能的轧辊轴承润滑脂,与以前轧机使用的极压锂基润滑脂相比,这是专门针对钢厂轧机设计的一种能够延长换脂周期的润滑脂。通过轧辊轴承润滑脂在西北一家钢厂轧机上的应用,证明该产品性能完全满足轧机高温、高负荷和水冲刷工况的使用要求,并使其换脂周期从30天提高到45天,使用轧辊轴承润滑脂全年的润滑费用降低近6万元。在检维修周期延长后,减少检维修次数,全年轧钢工段可降低润滑费用和检维修费用共计约40万元。保障了钢厂轧机的正常运转,降低了工人的劳动强度和生产成本。

A roller bearing grease with high temperature, high-load and good water resistance is mainly described in this paper. Compared with extreme pressure lithium based grease used before, this grease is designed specifically for steel rolling mill to prolong its grease change period. The application result in a steel rolling mill of the northwest showed that the roller bearing grease can meet all the rolling requirements, such as high temperature, high-load and water flushing conditions, and prolong the grease change period from 30 days to 45 days. The cost can be reduced about 60000 Yuan a year. Additionally, after prolonging the period of inspection and repairing, times of inspection and repairing can be also reduced so that the annual total cost in lubricating and repairing can be saved about 400,000 Yuan. So, it ensures the steel rolling mill normal operating, and reduces the labor intensity and production cost.
