Abstract

Molten steel temperature is a key parameter related to LF refining, and it has an important influence on steel quality and casting. Aimed at a steel ladle with capacity of 300 tons, a heat transfer model was developed. Ladle wall and bottom lining temperature distribution curve was obtained. The factors influencing LF endpoint molten steel temperature was analyzed. The results show that LF endpoint molten steel temperature would reduce 8-11ËšC if ladle repair time extends 30 minutes. LF endpoint molten steel temperature would raise 4ËšC if ladle is baked for 30 minutes. The rate decreases with the extension of baking time. The temperature would increase 1.5ËšC if baking gas temperature increases 200ËšC. The temperature would reduce 1.0ËšC if awaiting time increases 5 minutes.
