通过现场取样检验的方法，对汽车梁用热轧钢板表面氧化铁皮的宏观形貌、厚度、微区化学成分、组织结构及O/Fe质量百分含量进行了研究，分析了汽车梁用钢表面氧化铁皮产生的原因并提出了解决办法。经大批量工业生产和用户使用表明，产品表面光洁，冲压性能优良，完全满足冲制汽车纵梁和横梁的使用要求。

Macro-morphology, thick, micro-chemical composition, structure and the mass percent content of O / Fe of the surface iron oxide skin of automotive beam steel were investigated by samples collected in factory. We analyzed the cause the surface iron oxide skin of automobile beam steel, and also proposed a solution. Large quantities of industrial production and feedbacks of users explain that products with smooth surface and excellent stamping performance can fully fully satisfy the application requirements of automotive longitudinal beam and beam.
