Abstract：Aiming at the problem of abnormal slab during the steelmaking process of Baosteel， the field tracking and analysis were carried out， and the results showed that the slab anomalies during the steelmaking process were mainly concerned with the abnormal superheat and liquid level fluctuation. The study found that time interval between each procedure of steelmaking is not appropriate， and it is easy to cause a low temperature coincidence rate between procedures； the instability of casting speed during the production process of the head and tail slab and transition slab of different steel grade and the large argon flow during normal slab continuous casting process， both are easy to cause the liquid level fluctuation， further resulting in abnormal slab. By setting the corresponding train timetable， improving of steelmaking production schedule， and optimizing the argon flow during the continuous casting， the abnormal of superheat and liquid level fluctuation during the continuous casting process were controlled， thus the abnormal slab yield was effectively improved.
