根据Froude数相似准则 ,做了铝铸轧铸咀型腔熔体流动的水模拟实验 ,其结论 :现有铸咀出口处熔体流动速度相对误差达19 %以上 ,不能满足超薄快速铸轧工艺的需要
According to the similarity criterion of Froude number, the water simulation experiment of cavity melt flow in aluminum casting nozzle was made. The conclusion is that the relative error of the melt flow rate at the exit of the existing casting nozzle is more than 19%, which can not satisfy the requirements of ultra-thin rapid casting and rolling The need of craft
