中高碳钢冷蚀低倍检验与质量改善

Cold Etching for Macro Structure Evaluation and Quality lmprovement of Medium/High Carbon Steel

为了改进中高碳钢的铸坯质量 ,研究了一种专门的冷蚀检验操作法 ,可以清楚地显示中高碳钢低倍结构和缺陷 ,其检验结果可用来指导调整铸造工艺 ,从而改进铸坯质量。

In order to improve the slab quality of medium/high carbon steel a special cold etching method has been developed by which the macro structure and deficiencies of the medium/high carbon steel can be shown clearly in the evaluation process. The results of evaluation could be used as the guide line for adjustment of casting process and improve the slab quality.
