Study of shrinkage processes in the mold during casting of continuously cast round billet with diameter of 200 mm

The study investigates the influence of shrinkage processes in the mold of a continuous casting machine on the formation of surface defects during the casting of a 200 mm diameter round billet. The necessary shrinkage criteria for the continuously cast billet were determined to form an optimal shell by selecting molds with a specific geometric configuration and by using slag‑forming mixtures of customized chemical composition.
