【摘要】 使用拉伸、冷轧等方法,利用SEM、EDS、XRD等手段对比分析钢材表面除鳞方法。结果表明:氧化铁皮由最外层红色Fe₂O₃,中间层为磁性Fe₃O₄,以及最内层的维氏体组成。以磷酸为基底的复合多元酸GF2&GF1可以进行酸洗以去除氧化铁皮,且效果好于盐酸。机械除鳞时压应力的除鳞效果显著好于拉应力,为了达到破鳞效果,必须迫使钢材产生较大变形。更多还原

【Abstract】 The method of phosphorous removal was analyzed by means of SEM, EDS, XRD, stretching and cold rolling. The results show: The oxide scale consists of the outermost red Fe₂O₃, the middle layer is magnetic Fe₃O₄, and the innermost layer is wustite. The phosphoric acid-based composite polyacid GF2 & GF1 can be acid washed to remove the oxide scale, and the effect is better than hydrochloric acid. Pressure stress descaling effect is significantly better than the tensile stress during mechanical descaling. In order to achieve the scale effect, the steel must be forced to produce a large deformation.更多还原
