在电子万能试验机上通过压弯的方法研究了高碳钢盘条氧化铁皮的机械剥离性。采用不同工艺的冷却试验获得了不同特性的氧化铁皮试样，针对不同厚度和微观组织的氧化铁皮试样，经弯曲试验获得不同氧化铁皮的剥离尺寸。结果表明，氧化铁皮的剥离性与其厚度呈正相关关系，与FeO层和Fe3O4层的层厚比呈负相关关系。氧化铁皮的剥离过程受应力状态的影响，与拉应力相比，压应力的剥离效果更好。适当提高高温氧化温度，延长氧化时间；降低600℃以下冷却速度，提高Fe3O4的生成量，均可提高盘条氧化铁皮的机械剥离性。
The descaling property of the oxide scale of high carbon steel wire were researched by the method of bend-ing based on the electronic universal testing machine. Various characteristics of the samples of oxide scale were obtained through different cooling experiments. The descaling size of oxide scale samples with different thickness and microstruc-ture was obtained by bending test. The results show that the descaling property of oxide scale was positively related to its thickness and negatively to the thickness ratio of FeO and Fe3O4. The descaling process of the oxide scale was affected by the stress condition and the descaling effect was better by compressive stress rather than tensile stress. Increasing oxi-dation temperature and oxidation time,reducing the cooling rate below 600℃and increasing the amount of Fe3O4 can all improve the descaling property of the oxide scale.
