摘要

Based on Cr microalloying, the influence of V, Nb, Ti and their interactions on casting blank macrostructure and segregation were studied.The results show that Nb has great influence on the refinement of dendrite, which obviously influences carbon segregation in the range of addition, reducing carbon segregation with the increase of Nb addition. In V microalloying, V-Nb microalloying and V-Nb-Ti microalloying, carbon segregation evidently reduces with the increase of V addition. Ti has not apparent influence on carbon segregation in the range of addition, but obviously reduces Mn segregation. To some extent V, Nb and Ti reduce Mn, Si and S segregation.
