Technical Key Points

For small and medium-sized pump body castings, we usually set pouring system in the horizontal parting surface, with semi-circular horizontal runners and scattered inner runners, so as to reduce hot section and expands the filling surface, in the premise of ensuring the cross-sectional area, try to increase the width thickness rate (7: 1-5: 1). For larger pump castings, surface area is large and flow route of molten steel is long, so the temperature of steel drop fast, normally we use the bottom injected open-type pouring system, to achieve effective, fast and smooth filling.
