APPARATUS AND METHOD FOR FORMING OF A WIDE SIDE WALL FOR A CHILL MOLD INTENDED FOR A THIN SLAB CASTING INSTALLATION

摘要

A method of forming a wide side wall of a chill mold for a thin slab casting installation and which has a bulged widened region proceeding from the upper edge of the wall and terminating toward the sides and toward the bottom of the wall, includes making the wall of copper with a thickness of 5-50mm, and forming the bulged widened region under tension or a combination of tension and compression conditions. The apparatus for performing the method includes a bottom plate die with an appropriate contoured face, and a power-operated upper die the end face of which is shaped to match desired bulge of the widened region of the wall and cooperates with the contoured face of the bottom die plate to form the widened region.
