采用有限差分和二维稳态层流模型，应用边界适体坐标（ＢＦＣ）技术对异径双辊薄带铸轧熔池中钢液的流动进行了数值仿真·分析了铸辊转速、液面宽度、浇注区宽度、浇注位置等操作和设计参数对流场的影响·计算结果表明钢液注入熔池后，在双辊相向转动的作用下，会引起强制对流并产生２个逆时针方向的回流区·通过对不同工况的分析指出浇钢时采取低压头、偏流浇注并维持一定的液面高度等操作有利于铸轧过程的稳定进行·
The finite difference and two-dimensional steady-state laminar flow model was used to simulate the flow of molten steel in the molten pool with different diameter and double-roll strip casting by using BFC technique. The effects of casting speed, Width, pouring zone width, casting position and other operating and design parameters of the flow field of the impact of the calculation results show that the molten steel poured into the pool, the two rollers in the opposite rotation will cause forced convection and produce two counterclockwise Reflux zone · Through the analysis of different conditions, it is pointed out that the operation of adopting low pressure head, pouring at a constant flow rate and maintaining a certain level of liquid level is conducive to the stability of the casting process
