Abstract
A mathematical heat transfer model was built to simulate temperature, shell growth and phase transformations in continuous casting based on the technical conditions of the bloom caster of some steelmaking plant. The simulation result is coincided with the measurement. The effects of the operation parameters including casting speed, bloom size and steel melt superheat on the solidification process were discussed and the means of enhancing the bloom temperature was brought forward. The research results have been applied in the practical manufacture process to compute the best casting speed, to control the flow rate of secondary cooling water and to optimize the spray pattern of secondary cooling zone. The bloom quality and productivity could be improved.
