摘　　要：常温状态下的运动副通常采用油脂类润滑剂润滑,热连轧机生产线上的冷床由滚盘、轴套和销组成的转动副,处于380℃以上的高温工作环境,必须喷涂特殊耐磨、耐高温润滑剂,但其涂层厚度难于控制,涂覆和固化比较困难。为此,从涂层要求和涂料性能入手,经过喷涂和浸涂两种涂覆方式小批量零件试验,从涂层厚度、附着力等对比试验数据结果分析,确定以喷涂方式作为冷床转动副零件表面最终涂覆方案。设计了喷涂工艺与专用喷涂工装,对不同结构的批量件进行涂覆与热固化,工作效率显著提高,并应用在摩洛哥2800热连轧机生产线上的冷床"输送链"上,取得了成功。The kinematic pair in the normal temperature is usually lubricated with grease and lubricant. The cooling bed on the hot rolling mill production line is composed of roller, shaft and pin. The working temperature is above 380℃, and must be sprayed with special wear and high temperature. Lubricants, but the coating thickness is difficult to control, coating and curing more difficult. In this paper, from the coating requirements and coating performance, after spraying and dip coating two small batch parts test, from the coating thickness, adhesion and other comparative test data analysis to determine the way to spray as a cooling bed surface parts final coating scheme. The spraying process and the special spra- ying tooling were designed, and the coating and heat curing of the batches with different structures were improved and the working efficiency was improved. veyor chain of the 2800 hot roiling mill production The application was successful in the cooling conline in Morocco.
