【摘要】 针对大规格圆钢(φ120m)轧后存在内裂纹的现象,利用有限元软件 DEFORM、ANSYS 对形变应力和热应力进行了模拟计算,并计算了相变后所产生的组织应力,根据三种应力的耦合结果,指出了圆钢内裂产生的主要原因是形变应力所致,生产中应通过优化孔型,降低终轧道次形成的心部拉应力.
【Abstract】 In order to solve the problem of internal crack of large size round bar (φ120mm)after hot rolling,deformation stress,thermal stress and transformation stress were coupled in this paper.The numerical simulation under software of DEFORM and ANSYS was applied to analyze the deformation stress and thermal stress.Result shows that deformation stress is the main reason of crack,so central tensile stress can be reduced through optimizing design of passes in practice.
