摘　　要：结合现场工艺参数 ,试验研究了奥氏体再结晶区平均道次变形量及奥氏体未再结晶区变形温度对钒微合金化低碳钢形变奥氏体、铁素体、珠光体组织及力学性能的影响。与工业产品对比 。According to the industrial rolling technology,the influence of rolling parameters on the microstructure of austenite, ferrite and pearlite,and mechanical properties of vanadium micro-alloyed low-carbon steel plate were studied in this paper.These rolling parameters included average pass reduction above T_(nr)(non-recrystallization temperature)and rolling start temperature below T_(nr).By contrast with the specimen produced in the factory,it was found that the reduction of rolling start temperature below T_(nr) contributes greatly to the grain refinement and the mechanical propertics improvment.
