摘　　要：文章从CSP薄板坯连铸机生产SS400Ti产生纵裂的原因分析出发,通过对裂纹源进行电镜扫描分析,导致纵裂纹产生的真正原因为结晶器保护渣变性。结合CSP生产线多年的生产实践,总结归纳出CSP生产线生产SS400Ti中纵裂问题的控制和解决路径。为减少纵裂缺陷,提高热轧产品的合格率提供帮助。In the paper,the cause of longitudinal crack in the production of SS400Ti from CSP thin slab caster is analyzed,and through the electron microscopic scanning analysis of crack source,the real cause of longitudinal crack is degeneration of mould fluxes.Combined with production practice of CSP production line for many years,the control and solving path of longitudinal crack of SS400Ti production line in CSP production line are summarized.Provide help to reduce the longitudinal crack defects and improve the qualified rate of hot-rolled products.
