Abstract

An improved apparatus for pouring molten metal into a mold or other cavity. The apparatus includes a tiltable pouring ladle having a pouring spout disposed coaxially with the axis of rotation or tilt of the ladle to permit pouring of metal in a direction coincident with such axis of rotation. The apparatus is further provided with a positionable pouring trough for directing molten metal from the pouring spout to a pouring cup located at any position on the mold surface. With this apparatus, a fixed relationship between the pouring spout, the pouring trough, and the mold surface at any phase of the pouring process may be maintained such that the trajectory of molten metal being poured through air is minimized. The ladle is shaped such that molten metal may be poured at a rate proportional to the tilting rate of the ladle. The ladle also includes apparatus for preventing impurities such as slag or dross inclusions introduced into the ladle with the molten metal from being poured into the casting. The entire apparatus is contained within a frame permitting it to be readily attached to a coventional crane or monorail system as an easily effected substitute for a conventional manual pou…
