RUNNER SUPPLYING SYSTEM FOR LOW-PRESSURE CASTING OF LARGE-SIZED INGOTS FROM ALUMINIUM ALLOYS

摘要

Usage: for casting of large castings of aluminum alloys of complex configuration at low pressure in the presence of a large number of casting massive thermal units. SUMMARY OF THE INVENTION: powering a gating system consists of a riser metalloprovo- yes 1, collector 2, configured as a trapezium anisoplural and uniformly tapering the ends, the lower tier feeders 3, 4 and the bosses of the upper tier feeders 5. Thus the lug 4 are arranged vertically on an upper horizontal manifold 2 and bonded to at least one light brown feeders 3. Moreover, the ratio of cross sections lloschadey riser-metalloprovoda, collector bosses and feeders feed is 1: (0.8 ... 0.9) (2 .. 3): 4 min. 4 yl.
