降低高线粗中轧机轧辊轴承消耗的措施

Measures of Decreasing Roll Bearing Consumption in Roughing and Intermediate Mill of High-speed Wire Rod Mill

分析了高速线材生产线上粗中轧机轧辊轴承损坏的原因,并针对轧辊轴承的组装、清洗、检查、使用和维护等方面提出了相应的改进措施。实践表明,改进后该轴承的平均使用寿命由原产钢12万t提高到20万t。

The causes of roll bearing failure used in roughing and imermediate mill of high-speed wire rod production line were analyzed.The counter-measure were put forward about assembling, washing, examining, using and maintaining. The practical production show that the service life of bearing increased from 12 × 10^4t to 20 × 10^4t steel.
