采用金相显微镜和扫描电镜分析了含铌微合金化钢铸坯角部横裂纹的形成原因。
The optical microscope and SEM were applied to analyze the formation mechanism of transverse corner cracks of Nb microalloyed steel slab.
分析了含铌钢铸坯横裂纹的影响因素,并提出控制措施,取得良好效果。
The present paper analyzes the influential factors for the transverse crack in the CC slab and puts forward the control measures. Better results have been achieved.
含铌钢由于含有铌等裂纹敏感性元素,其铸坯横裂纹发生率远远大于其它钢种。
The transverse cracking rate of the Nb containing slab is far greater than that of other steel grade since the former contains Nb and other cracking susceptive elements.
