针对宽板坯连铸生产现状,采用商业软件PHOENICS对其建立三维数值模型,模拟宽板坯连铸结晶内钢液的流场分布。研究了不同水口倾角、插入深度及拉速等参数条件对结晶器内流场的影响,得出了适用于宽规格结晶器合理的浸入式水口。这为优化宽板坯结晶器内钢液的流场及浸入式水口结构及确定合理的工艺参数提供了科学依据。
Aiming at the production status of wide slab continuous casting, a three-dimensional numerical model was set up by commercial software PHOENICS to simulate the flow field distribution of molten steel in wide slab continuous casting. The influence of different nozzle inclination, insertion depth and casting speed on the flow field in the mold was studied, and a reasonable immersion nozzle suitable for wide mold was obtained. This provides a scientific basis for optimizing the flow field of liquid steel and the structure of submerged entry nozzle and determining the reasonable process parameters in wide slab mold.
