<p>FIELD: process engineering.SUBSTANCE: invention relates to metallurgy. Gating system comprises central riser with diverging lower part, horizontal runners, vertical runner, runner feeders, central metal intake and horizontal circular collector. Central metal intake is composed of a square located at the runner lower part. Angles of central metal intake accommodate horizontal runners connected with vertical runner. Gating system comprises four runner feeders arranged in horizontal plane at 90-0 degrees relative to the mould centrifugal rotation speed vector.EFFECT: higher quality of metal intake capacity and melt unobstructed flow.8 dwg, 2 tbl</p> |
