Formation Mechanism of Shrinkage Porosity and Process Optimization in Wheels of Heavy Trucks
Addressing the porosity and shrinkage issues encountered during the casting process of heavy-duty truck wheel hubs,a combination of sequential solidification and equilibrium solidification theories was employed.Casting simulations were conducted using Huazhu CAE software to optimize the feeding and risering system.The optimized gating and risering system significantly reduced solidification time and minimized the defect rate caused by porosity and shrinkage.The results showed that the structural integrity and physicochemical properties of the castings met the required standards.This study provides a valuable reference for improving casting quality and optimized casting processes.
