用有限元模型研究液心连铸板坯矫直过程，用与时间有关的加载过程的三维几何图形模拟整个矫直区域的铸坯截面的变化情况。用该模型可以解释粘弹性材料的各种性能。因为钢水有静压力，所以鼓突和矫直变形同时存在。在滚筒处预先规定了接触边界条件；用近似法描述坯料内部的... The finite element model was used to study the straightening process of liquid-slab continuous casting billets. The 3D cross-sectional geometry of the loading process was used to simulate the change of slab cross section in the straightening area. This model explains the properties of viscoelastic materials. Because the molten steel has static pressure, so the bulge and straightening deformation exist. The contact boundary conditions are pre-specified at the drum; the approximation is used to describe the internal ...
