摘要
改善高碳钢盘条氧化铁皮的剥离率,有助于提高其拉丝成材率。通过扫描电镜显微分析技术研究了高碳钢盘条氧化铁皮剥离后内表面的微观形貌,系统分析了内表面皱褶产生的机理,根据断裂力学理论给出了内表面皱褶起伏的高度和长度与其剥离性能的关系。通过拉伸试验结果与电镜扫描图片对比,研究发现内表面皱褶起伏的高度越小、长度越大就越有利于高碳钢盘条氧化铁皮的剥离。
it would be helpful to improve the yield of wire drawing when the ratio of oxide scale on high carbon steel wire was improved. The morphology of internal surfaces of stripped oxide scale on high carbon steel wire was studied by SEM microscopic analysis, the mechanism of internal surface corrugation was analyzed systematically. The relationships between the stripping performance and the height and length of the corrugation on the internal surface relief were given by fracture mechanics. Comparing the tensile test results with SEM, the conclusion was proved, that height of corrugation of internal surface was the greater and the length was longer, it was more conducive for the stripping performance of oxide scale on high carbon steel wire.
