Abstract

A slag stopper assembly for use in a tundish vessel includes a chamber for reducing the flow of slag to the tundish drain and a stopper plunger for regulating the flow of liquid metal through the drain. The chamber includes a central opening for receiving the stopper plunger, and the stopper plunger is retractably movable relative to the chamber through the central opening. In accordance with the invention, a sealing rim is present on the stopper plunger, or on an inner wall of the chamber, or both, in order to reduce the retractable movement of the stopper plunger, reduce the amount of slag which enters the chamber as a result of such movement, and seal off the central opening of the chamber from the tundish drain when the stopper plunger is in a retracted position.
