Abstract

The presented research was focused to optimize the conditions in a T-shaped three-strand tundish to minimize the intermix zone during steel casting. The intermix zone occurs when different steel grades are cast in a single sequence without interruptions or restarts, resulting in mixing of old and new steel grades in the tundish and the continuous cast billet. To achieve maximum steel casting efficiency, the conditions of the tundish were optimized to minimize the intermix zone. The study is focused on investigating the starting height of the steel level in the tundish before opening the pouring ladle and the duration of the steel level in the tundish after opening the pouring ladle for a specific time period. The SimCont physical model was utilized to realize the research.
