The defect-free continuous casting billet technology is an eternal theme in modern continuous casting techniques, serving as the foundation and prerequisite for the hot delivery and hot loading process of continuous casting billets. Current measures and new technologies employed to prevent defects in continuous casting billets include:

(1) Utilizing bulk slag detection technology, the primary objective is to prevent bulk slag from entering the tundish, thereby enhancing the cleanliness of the steel in the tundish.

(2) Utilizing crystallizer electromagnetic braking technology to reduce casting flow impact and enhance quality.

(3) Automatic crystallizer liquid level control.

(4) Compaction Casting Technology.

(5) Electromagnetic Stirring

(6) Developed casting billet surface defect detection technology.

(7) Casting Billet Quality Management.
