Comparison of the effects of different lubrication methods on wear and energy consumption of stainless steel cold rolling equipment
不同润滑方式对不锈钢冷轧设备磨损及能耗的影响比较

摘要

不同润滑方式对不锈钢冷轧设备的磨损状态与能耗水平存在显著差异。油基润滑、水基润滑及固体润滑作为主流方式，在摩擦系数调控、磨损产物生成及能量转化效率等方面呈现不同特性。油基润滑凭借高附着力可形成稳定油膜，但易因残油堆积增加清理能耗；水基润滑冷却性能优异却可能加剧轧辊锈蚀磨损；固体润滑能适应高温环境，却受限于膜层承载能力。通过对比三种润滑方式下设备关键部件的磨损量、表面粗糙度及单位产量能耗数据，揭示润滑机理与设备性能的关联规律，可为不锈钢冷轧工艺的润滑方案优化提供依据，对降低生产成本、延长设备寿命具有实践价值。

Abstract

Different lubrication methods exhibit significant differences in the wear status and energy consumption levels of stainless steel cold rolling equipment. As mainstream approaches, oil-based lubrication, water-based lubrication, and solid lubrication demonstrate distinct characteristics in friction coefficient regulation, wear product generation, and energy conversion efficiency. Oil-based lubrication can form a stable oil film due to its high adhesion, but it tends to increase cleaning energy consumption due to residual oil accumulation. Water-based lubrication has excellent cooling performance yet may exacerbate roll corrosion and wear. Solid lubrication can adapt to high-temperature environments but is limited by the load-bearing capacity of the film layer. By comparing the wear amount, surface roughness, and energy consumption per unit output of key equipment components under these three lubrication methods, the correlation between lubrication mechanisms and equipment performance is revealed. This provides a basis for optimizing lubrication schemes in stainless steel cold rolling processes and holds practical value for reducing production costs and extending equipment service life.
