Zusammenfassung:The invention belongs to the field of steelmaking continuous casting, and relates to an operation method for discharging a tail billet of a slab continuous casting machine, which comprises the following steps of: adopting a water-free top sealing mode after a tundish stops pouring, placing a cover plate on a crystallizer opening skin, setting a constant pulling speed, and adopting a manual timing calculation mode when the tail billet is discharged to a crystallizer lower opening; a worker does not need to stand at an upper opening of the crystallizer to observe the tail blank process, and potential safety hazards can be effectively eliminated. 本发明属于炼钢连铸领域,涉及一种板坯连铸机出尾坯操作方法,通过中包停浇后采取无水封顶模式,在结晶器口皮放置一个盖板,同时设置恒定的拉速,采取人工计时计算尾坯出至结晶器下口时转模式,不需人工站在结晶器上口观察出尾坯过程,能够有效消除安全隐患。
