BD 轧机为特钢新区 100t 电炉主要轧机。轧钢为初轧钢坯所需辊轴粗大轧辊颈所配轴承直径 1.4m 期间为四列滚珠初轧钢坯带给轧辊的力矩巨大自然对轴承径向载荷的能力要求也较高。轴承好坏直接影响整个初轧生产甚至对最后的成品合格率也会有较大的影响。对于四列滚珠轴承现场环境恶劣性能和寿命都取决于轴承润滑。如果轴承内部缺少润滑寿命会大幅度减少。轴承润滑分为脂润滑和油润滑。目前轧机采用的润滑为油润滑效果较差铁屑等杂质很容易混入其中大大降低了轴承正常使用寿命。现改造为使用脂润滑脂润滑的润滑脂流动性小且有密封的效果设备简单可靠拆装方便而且补充脂方便。BD 轧机为热轧采用脂润滑效果更好。改造后运行顺畅轴承的使用寿命大幅度延长收到了生产方的良好赞誉。
