摘要/Abstract

摘要： 开发了用于模拟高碳钢高速线材生产过程中断面温度分布,奥氏体组织演变和产品性能的系统数学模型组。由实验确定的临界应变、奥氏体再结晶、斯太尔摩冷却线上奥氏体相变、组织和力学性能关系子模型耦合轧件温度场,构建了一个组织性能预报系统。该系统所计算出的轧制线上关键点钢材温度,奥氏体晶粒度和力学性能与实测值吻合较好。

Abstract: A systematic mathematical model group has been developed to simulate the billet section temperature distribution,austenite structure evolution and products properties. "Die prediction system for structure and properties is established based on the sub-models determined by test including critical model, austenite recrystallization, phase transformation in steel at Stelmor cooling line and relation between structure and mechanical properties to couple temperature fields of billet. Hie billet temperature at key point of rolling production line, austenite grain size rating and mechanical properties calculated by this system are in agreement with measured value at situ.
