摘　　要：对唐钢FTSC工艺薄板坯出现表面纵裂纹的原因进行了分析,认为结晶器铜板形状、镀层质量、水口流场、扇形段对中、保护渣性能和钢水质量是导致纵裂发生的主要因素,据此提出了改进措施,使薄板坯连铸表面纵裂得到有效控制。The reason of longitudinal crack on surface of thin slab with FTSC process is analyzed. It is considered that the main factors include followings： the shape of copper board of mold, quality of painting layer, nozzle flow field, center-alignment of segment, performance of protecting slag and quality of smelting steel. Some improving measures proposed.
