Influence of Pouring System on Casting Deformation
Advanced equipment castings require internal stress to be as small as possible to prevent casting deformation and crack-ing.This paper discusses the influence of pouring system on the internal stress and deformation of castings,and lists the forms of pouring system that can prevent the deformation of castings in actual production,including the form and location design of sprue,runner and gate.Through the design of proper pouring system,the internal stress of castings is reduced,and the deformation and dimensional out-of-tolerance defects of castings are avoided.
