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.
Claims16
In a continuous-casting operation in which a workpiece at an elevated temperature travels within a casting machine and is subject to having cracks form in its corners, a method of flame-cutting a cracked corner portion from the workpiece comprising moving the workpiece past a cutting torch which is aimed at an angle of about 80.degree. to 100.degree. with respect to a plane which bisects the adjacent corner angle of the workpiece, whereby the torch cuts the workpiece along a line spaced from the corner and removes a segment of material which is triangular in cross section.
In a continuous-casting installation which includes means for carrying a workpiece at an elevated temperature along a path of travel, the combination therewith of a flame-cutting apparatus for removing cracked corner portions from the workpiece, said apparatus comprising a frame adjacent said path, and at least one cutting torch supported on said frame, said torch being located adjacent a corner of the workpiece and aimed at an angle of about 80.degree. to 100.degree. with respect to a plane which bisects the adjacent corner angle of the workpiece, whereby the torch cuts the workpiece along a line spaced from the corner and removes a segment of material which is triangular in cross section.
