摘要
铸坯上的横裂纹是连铸板坯上较严重的缺陷之一,对铸坯质量影响较大。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。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 transverse crack is one of the most serious defects in the continuous casting slab and it has much greater adverse influence on the quality of the CC slab. 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. 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.
