Mold for continuous casting and manner null of width changing the time

摘要

PROBLEM TO BE SOLVED: To always bring a mold into contact with a cast slab near the corner part of the mold, even in the case of continuously casting the slab at high velocity. ;SOLUTION: The mold for continuous casting has a structure having a rectangular cross section shape and interposing the cooling surfaces 12a of short side 12 with the cooling surfaces of long side. The cooling surfaces of the long side are formed with the flat surfaces without curving and bending parts in the whole range from the inlet to the outlet. On the other hand, the cooling surfaces 12a of the short side 12 arranges the curving 12b and bending parts at the inlet 12aa so that the thickness t₁ at the center part in the width direction in the inlet 12aa is smaller than the thickness t₂ at the long side. Further, this curving 12b and bending parts are gradually changed so that the thickness at the outlet 12ab is a little larger than the thickness t₂ of the long side at the inlet 12aa and becomes the flat surface without curving and bending parts.;COPYRIGHT: (C)1999,JPO
