Abstract: Pour tubes for use in conjunction with slidable gate valves that regulate the flow of molten metal from the pour opening in a bottom pour teeming vessel are operatively positioned with respect to the gate valve collector nozzle by means of mounting apparatus of particular construction. A pouring tube is replaceably positioned in the apparatus which is operative to manipulate the tube within a confined space into its operating position with respect to the collector nozzle between the teeming vessel and a receiving vessel.

Abstract: A method and apparatus for flame-cutting cracked corner portions from continuously cast metal workpiece. The cutting torches are positioned adjacent the corners of the workpiece and are aimed downwardly at angles of about 35.degree. to 55.degree. with respect to the vertical and at angles of about 80.degree. to 100.degree. with respect to planes which bisect the corner angles of the workpiece. Preferably the torches are aimed downwardly at angles of about 45.degree. and approximately perpendicular to the bisecting planes. In this manner the depth of segment cut from the workpiece is closely controlled and the material removed from the workpiece is directed away from the surfaces thereof.

Abstract: A slidable gate mechanism for controlling flow of material from an outlet in the bottom wall of a vessel. The gate is mounted in a carrier which is supported for sliding movement under the bottom wall. Springs mounted on a side wall of the vessel act on the carrier to urge the gate upwardly toward the bottom wall. The springs are remote from the outlet and do not require air-cooling.
