Zusammenfassung:	A tundish cover for use with a treating ladle in the production of ductile iron is disclosed wherein the tundish cover is provided with a pouring spout, a pressure exhaust port, a treatment alloy charging tube, a slag removal port and mounting tabs to detachably connect the tundish cover to the treating ladle. The pressure exhaust port includes a floating cover to provide a host for oxide condensation during the treatment process. Removable covers on the charging tube and the slag removal port permit selective access to the interior of the treating ladle without requiring disassembly of the tundish cover from the treating vessel.
