摘　　要：利用不同热轧工艺获得不同微观结构的氧化铁皮,通过电子天平、扫描电子显微镜等分析了M510L钢表面氧化铁粉重量与氧化铁皮微观结构之间的关系。结果表明,相同厚度规格的M510L钢的表面氧化铁粉重量与氧化铁皮厚度及微观形貌有关,氧化铁皮厚度在7~9mm范围内时,M510L氧化铁粉重量主要与氧化铁粉微观形貌有关。微观结构特征为10%FeO+90%Fe_3O_4,且FeO呈岛状均匀分布在Fe_3O_4中,对应的M510L钢的氧化铁皮粘附性最好,表面氧化铁粉重量小于1.0g/m^2。Different microstructures of the oxide scales are obtained by different hot rolling proceslationship between the weight of iron oxide powder on M510L steel and microstructure of the oxide scale were analyzed by electronic balance and SEM. The results show that the weight of iron oxide powder othickness is related to the thickness and microstructure of the iron oxide scale. When he thickness of he oxide scale is in therangeof 7-9mm, theweight of M510L ironoxidepowder ismainly related toitsMicroscopicmorphology. The Microscopic characteristics are that 10% FeO adds 90% Fe3O4 , the oxide scale of M510L steel, whose FeO distrib-utes uniformly in Fe3O4 in the microstructure, has he best adhesion, and the weight of iron oxide powder is less than 1.0g/m2.
