| 摘 要： | 针对铝箔轧后退火时,轧制油对铝箔表面的污染进行分析研究.首先利用热重与差热分析仪对轧制油和添加剂的退火失重和差热曲线进行测定,发现轧制油随温度增加,经历了两个阶段变化:先大量挥发,后发生氧化.退火油斑的形成取决于后者,这从理论上解释了轧制油在退火时的热物性变化对铝箔退火表面的影响.

| Abstract: | It was analyzed that rolling oil stains form on the surface of an aluminum foil when the aluminum foil was annealed after rolling.The curves of thermal gravity and differential thermal analysis of rolling oil and additive were determined by means of a differential thermal analyzer.The results indicate that rolling oil has two phase changes with the increase of temperature.At first,rolling oil is volatilized in a large scale,and then oxidation occurs.The oxidation process is the main reason for the stains forming on aluminum surface,which theoretically reveal the effect of the thermal properties of rolling oil on the annealing surface. |
