| 摘 要： | 简述了枝晶腐蚀低倍检验技术在连铸生产中的应用。结果表明,枝晶腐蚀低倍检验方法不仅能够非常清晰地显示连铸坯中的缺陷和铸坯凝固组织全貌,而且提供了优化工艺和提高钢材质量的有效途径。同时,在此次检验中,采用砂带磨削代替砂轮磨削可大幅度缩短制样的时间并提高制样的质量。

| Abstract: | Application of low-power test technology for dendritical etching in the continuous casting production is introduced. The results show that the low-power test of dendritical etching can not only show the defects in continuous casting billet and the details of solidification structure, but also provide an effective way to optimize the process and improve the quality of steel. At the meantime, using belt grinding instead of grinding wheel can greatly shorten the time of sample making and improve the quality of sample making. |
