薄板坯结晶器内应力场的数值模拟

Numerical simulation of stress field in CSP slab mold

用Matlab工程数据计算软件对薄板坯结晶器内的应力场进行了计算,结果表明铸坯应力分布与结晶器形状密切相关。对薄板坯连铸而言,结晶器漏斗边缘处形状突变,应力集中,裂纹指数大,是一个裂纹敏感区域,这是导致薄板坯表面产生纵裂的力学原因。

The numerical simulation of stress field for slab in CSP mold is calculated using Matlab project data software. The results show that the stress distribution features depend upon the shape of mold. At the edge area of mold larger stress can be observed, which causes the vertical crack of slab in its surface.
