摘　　要：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。In fact, the life of work roll bearing of strip mill is rarely reached the target value of 3000-5000hs the designed servce life. Economical losses in domestic steel plants are great due to premature damage of roll bearing, especially when the inner ring is bonded with the roll neck, losses are even greater. In this artical, causes have been analysed. preventive measures put forward, and ways of extending service life explored.
