摘　　要：文章主要对沙钢80钢热轧盘条的氧化皮进行了初步研究,采用SEM观察了氧化皮的宏观形貌以及氧化皮的内、外表面形貌,并用XRD初步分析了其成分;同时,测量了氧化皮的厚度,并结合高温氧化机理,应用Tam-mann型抛物线方程,从理论上计算了氧化皮的厚度,这对于氧化皮厚度(质量)的控制具有指导意义。The steel 80＂s scale on wire rod of Shagang was primarily studied. The scale macroscopical feature and the feature of inner and outer surface were observed through SEM. The scale composition was primarily analyzed through XRD. At the same time, the scale thickness was measured. Associated with the oxidation mechanism at high temperatures and by the Tammann-type parabolic equation, the scale thickness was theoretically calculated. This has directive meaning for controlling the scale thickness （weight）.
