摘　　要：采用Gleeble-2000热/力模拟试验机模拟了FTSR(Flexible Thin Slab Rolling)工艺中高Nb钢HTP(High Temperature Processing)的动态软化行为,并建立了动态再结晶数学模型,得出了临界应变与Z参数之间的关系,为制定合理的轧制工艺提供了实验和理论依据。The dynamic recrystallization behavior of high Nb micro - alloyed steels was simulated by Gleeble-2000 thermal/mechanical simulation tester and a dynamic recrystallization model suitable for FTSR was developed. The relationship of critical strain and Z parameters was determined which can be used as guidance for high Nb micro- alloyed steel rolling.
