【摘要】 采用SIMPLER迭代方法进行数值计算,针对连续铸造过程中的结晶器内部紊流流场和结晶器弯月面表面的液位波动情况,进行了三维数值模拟和水模拟试验验证,并使用表面动能法定量表征液面波动情况。通过对不同拉速、水口浸没深度和水口出流角度下的紊流流场及液位波动情况的模拟计算,分析各工艺参数对于连续铸造结晶器内部流场分部和表面波动幅度的影响,为合理地设计水口结构和选取合适的浇铸工艺参数提供了可靠的理论依据。更多还原

【Abstract】 Fluid flow in the mold of slab continuous casting has especially effects to the thickness of shell and to avoiding breakout. High surface wave leads to slag inclusion of slabs. This study simulated the turbulence fluid and surface wave in slab continuous casting, which is confirmed by water simalating experiments. The 3-D simulation software Visual Cast aids parameter selection and nozzle construction in slab continuous casting.更多还原
