Nanolayer Degradation Deposits on Cold Rolled Steel Strip: The Influence of Rolling Oil Emulsions in Sequential Oxidative and Reductive Environments

冷轧钢带由必和必拓生产，是生产国际公认的澳大利亚产品ZINCALUMER Steel和COLORBONDR Steel的前体材料。冷轧过程中使用贵格化学公司提供的润滑油。当暴露在直接燃烧的热处理过程中时，纳米层表面残留物会从滚动的油膜中形成，并对随后熔化的锌合金对钢表面的润湿产生不利影响。这一合作研究项目将利用先进的热和表面分析技术，调查纳米层残留物形成的基本性质，目的是确定影响残留物形成的因素，并减少其影响。

Cold rolled steel strip, produced by BHP Steel, is a precursor material for production of internationally recognised Australian products ZINCALUMER Steel and COLORBONDR Steel. Lubricating oils supplied by Quaker Chemical are used during the cold rolling process. When exposed to the direct fired annealing process, nanolayer surface residues can develop from rolling oil films and adversely affect subsequent steel surface wetting by the molten zinc alloy. This collaborative research project will investigate the fundamental nature of nanolayer residue formation, using advanced thermal and surface analysis techniques, with the aim of determining the factors influencing residue formation and reducing their impact.
