METHOD AND APPARATUS FOR FLAME-CUTTING CRACKED CORNER POR- TIONS FROM CONTINUOUSLY CAST METAL WORKPIECES

摘要

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 DEG to 55 DEG with respect to the vertical and at angles of about 80 DEG to 100 DEG with respect to planes which bisect the corner angles of the workpiece. Preferably the torches are aimed downwardly at angles of about 45 DEG 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.
