摘要
Based on the achievement of high speed continuous casting in SGJT, fluid flow, heat transfer, and lubrication behavior were analyzed elaborately. The results indicated that well-bottom SEN with the angle of -20 degrees together with FC mold could reduce the level fluctuation effectively. When FC mold was applied at 1.9 m min(-1), there was an increase of average heat flux about 0.06-0.1 MW m(-2). During heat transfer analysis, the empirical equation of heat flux was proposed and solidification crater end was validated by pin shooting method. Furthermore, a kind of mold powder employed in high speed casting was described and a new criterion of the consumption rate for high speed casting was put forward.
