    • 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.
    • 用于在铸造期间将熔融金属转移到模具的紧凑且可重复使用的浇口装置采用类似于梯形块状耐火材料的基本上单一的结构。 在该块内是一个大致圆柱形的旋转室,一个入口通道,其容纳熔融金属并将其向切向地注入到旋转室中,使得金属迅速旋转以分离非金属夹杂物,以及将净化后的金属输送到模具 。 旋转室可以具有位于出口通道的开口下方的底部和从底部到至少开口稍微向外倾斜的壁,使得在底部固化的夹杂物和金属可以从旋转室 。 或者,出口通道可以在偏心位置处进入底部,使得所有的熔融金属都将被排出。
