Design of tapping Hole of Molten Metal to improve performance and cleaning

摘要

The present Invention relates to a casting Hole structure for container coated with Refractory MaterialContaining a Molten Metal that has a layer of slag and sobreyacente, where the tapping Hole extends through the side wall of the vessel in the Upper portion of the same.Through which the rotation of the container from an Upright position to a Tilted position.Cause the Molten Metal flow through the tapping Hole; The Hole structure of casting Refractory comprising: a member that extends generally tubular configurationThrough the side wall of the Container and has a Closed end portion that extends into the container side wall and Openings of the tubular Member closely ad RefractoryRecumbent a Closed end, which extends into the container through which the Molten Metal will not Flow directly towards the end of the tubular Member Refractory,Rather, will flow into the Refractory Member through the side wall openings, through which the slag will not materially vortices to the tapping Hole,The Container can be rotated at an angle with respect to the vertical during casting, and can get a higher amount of Free Metal in slag from the container.
