渗透探伤法在连轧坯和钢板表面质量检验中的应用

Application of Penetrant Method in Testing Surface Quality of Continuous Rolled Slab and Steel Plate

利用表面渗透探伤法对高碳钢连轧坯和轧后钢板的表面质量进行了检验,并且对缺陷形貌和来源进行了分析。结果显示,表面渗透探伤法能准确确定连轧坯和轧后钢板表面缺陷的位置。与酸浸法相比,表面渗透法更加直观、准确。

The surface quality of high carbon continuous roiled slab and steel plate after roiled are tested by penetrant method and the defaults morphology and resource are analyzed. The results show that the defaults places can be exactly determined by penetrant method which is more visual and accurate than acid leaehing method.
