Abstract RU 2167025 C2

FIELD: foundry; applicable in casting into metal molds. SUBSTANCE: gating system has porous changeable funnel, riser, feeder and pipeline for supply of inert gas. During pouring of metal into receiver whose cavity is limited by external side wall of funnel and walls of metal mold, inert gas is supplied through pipeline. Gas flow passing through porous funnel fills mold cavity and washes stream of poured metal to protect metal from contact with atmosphere. EFFECT: higher quality of castings due to prevention of metal secondary oxidation. 1 cl
