Abstract Dynamic recrystallization action for Nb bearing steel on flexible thin slab rolling has been investigated by Gleeble-2000 thermal/mechanical simulation tester. Considering the effect of Nb content, modelling of dynamic recrystallization have been studied. Research results show that with the increasing of Nb content, (the activation energy of dynamic recrystallization) increase and the value of is higher than that of the traditional hot strip rolling. With the increasing of Nb content, the value of A and n increases linearly, the value of m decreases linearly and the value of B increases. The calculated and experimental results are in good agreement. That is, the modelling of dynamic recrystallization can simulate the dynamic softening action for Nb bearing steel on flexible thin slab rolling and provide the direction for rolling technique.
