A Model Analysis of the Temperature Variation of Molten Steel in Continuous Casting Tundish

Tetsuya Fujii; Yasuhiro Habu; Hiroshi Ooi

Synopsis: In order to obtain the temperature variation of molten steel in tundish during the teeming of continuous casting, a mathematical model which consists of heat balance of molten steel in tundish has been developed. The results calculated from this model were compared with the data of operation of the bloom caster at the Mizushima Iron Works, and it was proved that this model was useful for
