用铝青铜铸造的蜗轮、螺母、轴套以及其它要求强度高和耐蚀耐磨的异形件,在冶金设备、机床等各类机械中有着广泛的应用。虽然可以用离心铸造生产某些套、环类铸件,但破型铸造毕竟仍是一种最主要的生产方式。这样,浇冒口的设计就是一个十分重要的问题。本文着重讨论冒口的设计,自然也会涉及到浇口设计中应注意的一些问题。 Aluminum bronze casting worm, nuts, bushings and other demanding high strength and corrosion-resistant wear-resistant pieces of shape, in metallurgical equipment, machine tools and other machinery has a wide range of applications. Although centrifugal casting can be used to produce certain sleeve and ring castings, after all, break casting is still one of the most important modes of production. In this way, the design of the riser is a very important issue. This article focuses on the riser design, will naturally involve the gate design should pay attention to some of the problems.
