Abstract NbC morphology of carbon round steel in niobium microalloying was studied and analyzed after rolling. According to the study, when the mass fraction of niobium in medium carbon steel is 0.03%, niobium carbide above 5 μm will be precipitated in the process of continuous casting solidification.When the heating temperature of billet rolling is about 1 250 ℃ and the holding time of high temperature section is more than 4 h, the solution of micron grade niobium carbide can be obtained.
