Abstract In this paper, the influence of rolling parameters on the generation of wear particles is studied experimentally using a pilot scale rolling mill. Further, a multi-scale wear model is proposed to predict the amount of wear particles generated in cold rolling processes operating under the boundary lubrication. Rolling experiments revealed that thickness reduction and roll roughness are the two dominant process parameters that control wear particles generation in cold rolling processes. Analysis of the wear particles size distribution showed that most of the wear particles are less than 5 μm in diameter. The proposed model captures the trend correctly and give values in the same order of magnitude as the experiments in terms of the volume of wear particles generated.

了解冷轧过程中磨损颗粒的产生

摘要 本文利用中试轧机对轧制参数对磨损颗粒产生的影响进行了实验研究。此外，提出了一种多尺度磨损模型来预测在边界润滑下运行的冷轧过程中产生的磨损颗粒量。轧制实验表明，厚度减小量和轧辊粗糙度是控制冷轧过程中磨损颗粒生成的两个主要工艺参数。磨损颗粒尺寸分布分析表明，大多数磨损颗粒的直径小于5μm。所提出的模型正确地捕捉了趋势，并根据产生的磨损颗粒的体积给出了与实验相同数量级的值。
