Abstract：In view of the frequent occurrence of “cold teeth”, bonding and more longitudinal cracks on the slab surface in the process of thin slab continuous casting at high casting speed. According to the solidification shrinkage characteristics of medium carbon steel and the actual production situation in the field, a kind of mold flux suitable for thin slab medium carbon steel continuous casting at high casting speed was developed. The production practice showed that with the increase of casting speed, the longitudinal cracks on the slab surface were basically avoided by using the new mold flux, and there were no alarm phenomena such as “cold teeth” and bonding. The quality of the slab was improved remarkably, which fully met the production requirements.
