Abstract (en)
[origin: US4741463A] A compact and re-usable ingate device for transferring molten metal to a mold during casting employs a substantially unitary structure resembling a trapezoidal block of refractory material. Within the block are a generally cylindrical rotation chamber, an inlet channel which receives the molten metal and injects it tangentially into the rotation chamber, so that the metal swirls rapidly to separate nonmetallic inclusions, and an outlet channel which conveys the cleaned metal to the mold. The rotation chamber may have a bottom that is positioned below the opening to the outlet channel and walls which slope outward slightly from the bottom to at least the opening, so that inclusions and metal that has solidified at the bottom can be removed from the rotation chamber. Alternately the outlet channel may open into the bottom at an eccentric position, so that all of the molten metal will be drained.
