通过实验研究，确定了连续包覆型腔汇合室中金属流动分流线的几何形态，并在此基础上建立了塑变区的速度场。该速度场描述的金属流动状态与金属的实际流动相吻合。由此速度场给出了型腔的几何参数与金属流动均匀性之间的理论关系式，并以金属流速均匀为目标函数，确定了最佳型腔几何参数。 Through the experimental study, the geometry of the metal flow shunting line in the continuous cladding cavity confluence chamber is determined, and the velocity field of the plastic deformation zone is established. The velocity field describes the state of metal flow that corresponds to the actual flow of metal. The velocity field gives the theoretical relationship between the geometrical parameters of the cavity and the uniformity of the metal flow. The optimal cavity geometry parameters are determined by taking the metal flow velocity as the objective function.
