摘要
用电子分析天平测量了热轧卷取板试样表面氧化铁皮的增重,用扫描电子显微镜(SEM)和能谱仪(EDS)观察测量了试样表面氧化皮形貌、氧化层厚度和成分,并用热力学方法进行了分析。结果表明,快速冷却时,试样氧化层形成3层结构,即Fe2O3→Fe2O3、Fe3O4→Fe3O→Fe;延长冷却时间,试样氧化层形成2层结构,即Fe2O3→Fe2O3、Fe3O4→Fe。
The increased weight ratio of the hot-rolled coiled sheet sample is measured by electronic analytical balance,and the surface,cross-section morphology,thickness and composition of the oxide scale are observed by optical microscope,scanning electron microscope（SEM） and energy dispersive spectrometer（EDS）.It is found that the oxide coating has 3-layer structure（Fe2O3→Fe2O3、Fe3O4→Fe3O→Fe） with rapid cooling.With the extension of the cooling time,it has acquired 2-layer structure（Fe2O3→Fe2O3、Fe3O4→Fe）.
