| 摘 要： | 针对FTSC薄板坯工艺生产热轧板卷存在的纵裂纹和烂边缺陷,对其形成原因进行了系统研究,并提出相应的改善措施.研究结果表明,板坯存在的宽面纵裂纹和窄面或角部横裂纹缺陷,将分别导致热轧板卷纵裂纹和烂边缺陷的形成.通过控制钢水温度,控制结晶器铜板厚度,降低二次冷却强度等措施,质量缺陷明显减少.

| Abstract: | Aiming at longitudinal crack and edge damage of hot rolled coil sheet by FTSC thin slab process,the authors conducted systematic study and put forward relevant improvement measures.Study results showed that slab longitudinal crack at wide side and transverse crack at narrow side or corner caused the formation of the above defects,which were remarkably minimized by controlling molten steel temperature and mould plate thickness and reducing secondary cooling intensity. |
