An equivalent simulation of finishing unit of hot strip rolling millwas carried out for austenite recrystallization. Hot deformation equation of auste-nite of 09MnNb steel was established, and the critical regression equations of dy-namic recrystallization were described as: σ_P=ε/5.75×10~(-7)·exp(96.3/RT)~(1/6.13) Z=8.51×10~9·e~(32.18~εC) Z=6.32×10~9·e~(16.99~εS) Austenite recrystallization taking place during hot deformation was explainedwith residue strain theory. It has been concluded that austenite dynamic recrystalli-zation of 09MnNb steel during hot deformation is the principal fining mechanismof austenite grain before transformation.
