摘要

把双辊铸轧熔池处理成钢水和大气的自由表面两相流

考虑了实际生产过程中铸轧辊的转动

建立了铸轧熔池内钢水三维流动传热耦合数学模型。通过此模型

计算并分析了采用楔形布流器时

铸轧熔池内钢水的流动形式和温度分布情况。结果表明

钢水在熔池内以布流器侧水口的位置为基准

在侧水口上部和下部区域分别存在着强弱程度不同的钢水回旋区域。Kiss点（凝固结束点）的高度在纵向上根据侧水口的位置近似呈余弦形式分布。

Abstract

Three-dimensional mathematical model coupling with fluid-thermal field was established for molten pool based on considering free surface between air and molten steel as two phase flow

where rotation of twin-roller was taken into account.Flow morphology

temperature distribution and solidification of liquid steel in the molten pool with adopting wedge-shaped inlet were simulated by the model.Simulated results show that two circulation flow areas exist at the top and bottom regions of the side-nozzle in the molten pool.The height of Kiss point distributes in cosine pattern similarly according to the position of inlet along the longitudinal direction.
