摘要
针对重卡汽车轮毂在铸造过程中出现的缩孔缩松缺陷问题,采用顺序凝固结合均衡凝固理论,利用华铸CAE进行铸造模拟,优化了补缩系统.优化后的浇冒口系统显著缩短了凝固时间,降低了因缩松缩孔造成的废品率.结果表明,铸件的结构完整性和理化性能均满足标准要求.本研究为提高铸件质量和优化铸造工艺提供了有益参考.
Abstract
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.
