Abstract (en)

[origin: US4437652A] The invention relates to a vessel for the continuous treatment of molten metals under reduced pressure, according to the circulation process. In order to increase the through put of the molten metal, the inlet and outlet pipes are located on the longitudinal axis of an elongated vessel-bottom, for example an elliptical vessel-bottom, a cross-section of the inlet and outlet pipes being enlarged. The lower portion of the vessel is bell-shaped. With this geometry of the lower portion of the vessel, the volume of the vessel remains small, despite comparatively large cross-sections of the inlet and outlet pipes, which can be located with an adequate clearance from each other and the walls of the vessel, so that the danger of erosion effects resulting from the circulating molten metal remains small.
