通过对轴向推力轴承烧熔原因的分析,提出了减小轧制轴向力的方法,为单机架六辊轧机提高工作辊轴承的寿命指出了研究思路。并在生产过程中不断完善轴承的安装、维护、保养以及对轴承座和附件检查制度,取得了较好的应用效果,使生产成本明显降低。 Based on the analysis of the causes of axial thrust bearing melting, the method to reduce the rolling axial force is put forward, which points out the research ideas for improving the service life of the work roll bearing in the single-stand six-high rolling mill. And in the production process and constantly improve the bearing installation, maintenance, maintenance and inspection of the bearing and attachment system, and achieved good results, the production costs significantly reduced.
