中文摘要：
在弄直的阶段的平板的变丑行为被明确的动态有限元素方法，和压力分发在连续的扔期间在平板中心沿着平板和它的变化整齐的宽度方向在连续的扔期间模仿被获得。分发的影响和平板表面上的纵的裂缝的繁殖上的应力的变化被讨论。紧张的压力在内部弧方面和压缩压力出现在平板表面上的结果表演在外部弧方面出现在平板表面上在在在连续的扔期间弄直地区上演 68。纵的裂缝通常在平板顶表面上出现并且不出现在平板底部表面上，它也在工业被观察。
英文摘要：
Deformation behavior of slab at the straightening stage during continuous casting was simulated by the explicit dynamic finite element method, and the stress distribution along the width direction of the slab and its change regularity at slab center during continuous casting were obtained. The influence of distribution and change of stress on the propagation of longitudinal cracks on slab surface was discussed. The results show that the tensional stress appears on slab surface at the inner arc side and the compressive stress appears on slab surface at the outer arc side at stages 6-8 in straightening zone during continuous casting. Longitudinal cracks generally appear on slab top surface and do not appear on slab bottom surface, which are also observed in industry.
