| 摘 要： | 基于实际生产测得的数据，采用连续动态三维耦合模型对板坯连铸凝固过程的流场、温度场和凝固进行模拟. 结果表明，由浸入式水口进入的钢液在结晶器内冲击形成上下两股回流，凝固促进了流动速度的衰减，提高拉速扩大了回流区域；结晶器内铸坯宽面偏角部100~150 mm处存在局部过热，在结晶器出口，拉速由0.02 m/s增加到0.025 m/s，坯壳厚度减小约3 mm.

| Abstract: | Based on the data obtained from actual solidification process of slab casting,a 3-D coupled model for describing flow field,temperature field and solidification of slab casting process was simulated with the continuum transient model.The results showed that the fluid flowed from the outlet of submerged entrance nozzle forming top and down recirculations in the mold zone,solidification promoted the decay of turbulent fluid flow speed and the region of recirculation was enlarged along with the casting speed i... |
