OPTIMIZATION OF TEMPERATURE CONTROL IN TH E TUNDISH BY INJECTION OF IRON-CORED WIRES

Objective. Due to the falling steel temperature in the steel ladle, th e steel superheat in a continuous easter tundish has a minimum tempera ture at the beginning of a cast, a maximum at around the midpoint of t he cast, and a minimum again towards the end of the cast. The quality criteria however require as constant a casting temperature as possible . This makes it necessary to precisely adjust the temperature in the l adle and to reduce the superheat in the tundish at the midpoint of the cast. The aim of the steel shop trials was to achieve a constant supe rheat in the tundish by cooling with iron-cored wires.
