摘要
本文根据某钢铁公司φ12 mm×4切分现场应用,通过有限元仿真,进行了切分孔型设计。就轧件成型中尺寸形貌、温度、力能载荷等变化,与轧制程序表进行了校对。与Eklund力能计算方法相比,得到了一些有用的结果:并联轧件在边部和中间的温差,会显著影响成品质量(线差和力学性能);应考虑预切和切分孔型设计中,轧件呈圆滑边部,降低散热;传统设计中无法加入并联轧件具体形貌,导致计算载荷较高;通过仿真得出:b=0.933d轧+b0,可准确预测圆-平孔系轧件宽展。
In this paper, reference to the φ12 mm ×4 slitting rolling field application of some iron &steel Co., and through the finite element simulation method, the design of slitting rolling pass is carried out. The change of the rolled piece forming size, morphology, temperature, force and energy load were compared with rolling schedule. Compared with the Eklund force energy calculation method, some useful results were obtained: the temperature difference between the edge and the middle of the parallel rolled piece will significantly affect the quality of the finished product(line difference and mechanical properties);in the design of pre-slitting and slitting pass, the rolling piece should be smooth edge and reduces heat dissipation;it is impossible to add the specific morphology of parallel rolling parts in traditional design, which results in high computational load;obtaining the empirical formula b=0.933 d Roll+b0 by finite element simulation method, which can accurately calculate the width of the rolled piece with circular and flat pass system.
