| 摘 要： | 采用刚塑性有限元方法并借助商业有限元软件对连铸坯三点矫直过程进行模拟分析,然后与一点矫直和连续矫直进行对比.结果表明,三点矫直过程中,应变均布在3个矫直段内,沿铸坯厚度方向,应力应变值在表面处最大,中性面偏向外弧侧,总应变值与理论值吻合较好;铸坯温度变化接近实际值.

| Abstract: | The simulation and analysis of slab three point unbending process were carried out using rigid-plastic finite element method(FEM) by commercial software,which is contrasted to one point unbending and continuous unbending.In the process of three-point unbending,there is uniform distribution of plastic strain in three piece fields while the plastic strain is the largest on the surface,and the neutral surface is bias to outer arc.The FEM result of the total plastic strain is in agreement with theoretic value and the slab temperature corresponds to the practical value. |
