宽厚板坯连铸结晶器流场、温度场及应力场的耦合数值模拟OA北大核心CSCDCSTPCD
Coupling numerical simulation of flow field, temperature field and stress field in a wide-thick slab continuous casting mold
利用ProCAST软件对2400 mm×400 mm宽厚板坯结晶器建立三维动态模型,采用移动边界法实现结晶器内流场、温度场及应力场的耦合模拟.结果表明:考虑凝固坯壳的影响,下回流区位置向铸坯中心靠拢,真实反映了钢液在连铸结晶器内的流动情况.自由液面的钢液从窄面流向水口,速度先增大后减小,距水口约0.7 m处,出现最大表面流速,约为0.21 m· s-1.结晶器出口坯壳窄面中心厚度最小且由中心向两侧逐渐增大,最小厚度约为10.4 mm;受流股冲击影…查看全部>>
Based on a moving boundary approach, a three-dimensional dynamic model is built for 2400 mmí400 mm wide-thick slab molds by using ProCAST to realize the coupling simulation of flow field, temperature field and stress field. The results show that the position of the lower recirculation zone moves to the slab center by the effect of the solidified shell, which reflects the real flow condition of molten steel in the continuous casting mold. The liquid on the fr…查看全部>>
