摘要
对Q235及HP295热轧板冷弯不合格试样进行了宏观观察及微观分析。结果表明表面质量是导致冷弯性能不合格的主要原因,另外钢坯皮下气泡、偏析、非金属夹杂物以及表面增碳也是导致冷弯不合格的原因。
The macroscopical survey and micro cosmic analysis of unqualified cold bending test samples of Q235and HP295hot -rolling plate had been stu died.The results show that the surfa ce quality of steel or test sample is a mainly reason causing unqualified c old bending property of the plate.Ga s bubble,the inclusion and carboniz ation of the plate surface are also reasons.
