摘要
18辊轧机工作辊止推轴承在使用过程中易损坏,通过分析发现主要是因为工作辊作用在止推轴承上的轴向力过大造成的,本文主要针对带钢板型呈楔形或镰刀弯、中间辊与侧支撑的作用力的因素讨论分析造成止推轴承损坏的原因,找到了延长止推轴承使用寿命的方法。结合机组运用的实际情况,经过相对应的优化措施改善后,能降低损坏率41.7%。
The work roll thrust bearing of the 18 high rolling mill is prone to damage during use.Through analysis,it is found that the main reason is the excessive axial force acting on the thrust bearing by the work roll.This article mainly discusses and analyzes the factors that cause damage to the thrust bearing,such as the wedge-shaped or sickle shaped steel plate shape,the force between the intermediate roll and the side support,and finds a method to extend the service life of the thrust bearing.Based on the actual operation of the unit,after corresponding optimization measures,the damage rate can be reduced by 41.7%.
