| 摘 要： | 基于计算流体软件Fluent,比较全面地分析双辊超薄连续铸轧的流场,特别是铸嘴型腔三维流动现象及其特点.分析铸轧区对流场的作用.铸轧区有利于铸嘴出口速度的均匀流动,有利于速度均匀混合,但不能彻底消除速度梯度.把计算的铸嘴出口处的流体速度与实验结果相比较,两者基本吻合,并得出结论:分流块的形状与位置是影响铸轧流场的主要原因之一,常规铸轧常用铸嘴熔体出口速度相对误差达38%,不能满足超薄连续铸轧技术的需要.

| Abstract: | Based on computational fluid software Fluent,a more comprehensive analyze the twin-roll casting of ultra-thin flow field.In particular analyze the nozzle casting three-dimensional flow phenomenon and its characteristics.For the first time analyzed the effect of the district casting upon the flow field,casting area can be propitious to flow uniformity of exit velocity,will help speed evenly mixed,but can not completely eliminate.Compare the nozzle casting exit velocity of the fluid with the experimental resu... |
