摘 要：<正> With the help of solidification kinetics, precipitation and growth of TiN have been studied theoretically and the effect of cooling rate on the growth of TiN has been discussed. Through induction electric furnace experiment and electroslag remelting experiment with different cooling rates, the distribution and particle size of TiN were investigated. It is proved that the higher cooling rate is, the smaller the final size of TiN is and the more TiN particles can be found in the steel. That TiN can restrain the growth of columnar crystal and enhance the proportion of equiaxed crystals to refine solidification structure as the heterogeneous nucleation sites of 8-ferrite is confirmed preliminarily. A new method to reduce macrosegregation in continuous cast steel is provided.
