摘　　要：QT500-10轮毂铸件常用于重型卡车。为了保证铸件具有较高的抗拉强度和较好的伸长率,并且同时提高生产效率、降低成本,在试制过程中对铸件的成分、浇注系统和泥芯结构设计等方面进行了有效的改进,从而在产品性能、成本控制方面获得了较大提升。QT500-10 wheel boss castings are often used for heavy-duty trucks. To ensure that the castings have a higher tensile strength and good elongation, and at the same time to improve production efficiency and reduce costs, the design of composition, the gating system and the core sand structure of the casting were efficiently improved in trial-produce. Thus the properties of products and cost control acquire bigger advance.
