轧机主轴平衡缸润滑技术的改进

介绍了1700机组R₂轧机主轴平衡系统的组成及工作原理,对主轴平衡缸使用过程中出现的润滑不良问题进行了分析和技术改进。实践表明,改进后保证了液压缸的顶头与顶臼充分润滑,主轴平衡缸振动大的问题得到改善,避免了断辊、研瓦的重大事故发生,同时大大减少更换液压缸的费用及时间,减少备件损耗,延长了备件使用寿命.

Improvement of Lubrication Technology for Spindle Balance Cylinder of Rolling Mill

Describe the composition and working principle of the balance system of the R₂mill spindle of 1700 unit.An analysis was made on the problem of had lubrication occurred in the operation of the spindle balance cylinder,and technical modification was carried out.The practice shows that a full lubrication on the head and socket of the hydraulic cylinder is guaranteed after taken improvement.Big vibration existing in the spindle balance cylinder is improved.The major accidents are avoided,surh as roller broken and bush abrasion.Meanwhile,the costs and time for replacing hydraulic cylintiers are greatly reduced.Spare parts consumption is decreased,and the service lifetime of spare parts is prolonged.
