摘 要:
SPAH钢是一种耐候钢，由于它具有良好的抗大气腐蚀的特性而被广泛用于集装箱制造。但该钢在生产线上有时会形成反常的红色锈层。本文采用模拟氧化实验的方法研究了温度对SPAH钢红色锈的影响。利用金相、扫描电镜和能谱等手段研究了红色锈层的微观结构，利用有限元方法模拟了CSP生产线上工件不同部位的温度分布状况。研究发现，生产线上形成红色锈层的部位在生产过程中在560℃左右停留的时间比较长，说明560℃是形成红色锈层的特征温度。[著者文摘]

Abstract:
SPAH steel is weathering steel widely used for manufacturing containers for its high corrosion resistance in atmosphere. However,red rust forms on the llne of compaction strip production（CSP）. Static oxidization method was used to study the effects of temperatures on the red rust. OM, SEM and EDX were used to study the layer of the red rust. And at the same time,a finite element method was used to simulate the distributed condition of temperature at different spot in the workpiece on the CSP line. Results show that the location with red rust on the products has undergone a relative longer time at 560℃ than that without red rust.[著者文摘]
