板带轧机工作辊轴承的设计使用寿命是3000～5000h,但实际上远达不到这一目标值。国内务钢铁厂因轴承过早损坏而造成的经济损失是很大的。当轴承内圈和辊颈粘接时,则损失更大。本文分析了原因,提出了预防措施,探索了延长工作辊轴承使用寿命的途径。 Strip mill work roll bearing design life is 3000 ~ 5000h, but in fact far less than the target value. Domestic steel plant due to premature bearing damage caused by economic losses are great. When the bearing inner ring and roll neck bonding, the greater the loss. This article analyzes the causes, puts forward the preventive measures and explores ways to prolong the service life of the work roll bearing.
