首钢中厚板四辊轧机工作辊轴向窜动研究

针对首钢3 500 mm四辊可逆式中厚板轧机工作辊轴向窜动问题,从工艺、设备以及操作角度全面分析了窜动的原因,对其进行理论分析,并结合现场实际采取相关措施,最终解决了工作辊轴向窜动的问题。为了防止工作辊轴向窜动再次发生,对中板轧机的日常管理和维护提出一些建议和要求,通过这些措施的实施,大幅度减少了设备故障时间,明显提高了生产作业率和经济效益。

Research on axial movement of working roll for four-high reversing mill of the medium and heavy plate in Shougang Group

The paper comprehensively analyzes the cause for movement in terms of technology and equipment and operation with regard to axial movement problem of working roll of 3500mm four-high reversing mill of the medium and heavy plate,and presents theoretical analysis thereof so as to take relevant measure based on actual situation on site and solve the problem of axial movement of working roll at the end.In order to prevent working roll from repeated axial movement,the paper comes up with some proposals and requirements in terms of daily management and maintenance for medium plate mill,the implementation of which shall greatly reduce equipment failure time and significantly enhance production operation efficiency and economic benefit.
