Simulation of Flow Field and Temperature Tield in the Process of Filling and Solidification for K424 Alloy Thin-Walled Casting

Abstract:

In order to improve the utilization of K424 alloy, Z-Cast analysis software is used to get three-dimensional flow field and temperature coupling simulation in the process of K424 alloy castings filling, by considering the effection of pouring temperature, casting speed, shell thermal conductivity and temperature on the morphology of filling.A three-dimensional simulation of temperature changes in solidification process of molten metal was performed based on the filling simulation. The simulation results on flow field and temperature field shows the order of filling and solidification in different parts of the casting ,and determines the position where cold shut and misrun appears, which provides theoretical support to the improvement of technology plan.
