PURPOSE:To improve the dimensional accuracy of a strip in the transverse direction thereof without strip crack in the stage of pouring a molten metal into a casting mold, cooling the molten metal and casting the strip by dividing the pouring part of the mold to a plurality in the transverse direction and making the pouring temp. to the specific divided part of the mold higher than the pouring temp. to the other divided parts. CONSTITUTION:The molten metal 3 supplied from a tundish 3 to a gate flask 2 is cooled by horizontal rolls 1 under rotation and a solidifed shell 5 is formed from the surface sides of the rolls 1. The shell 5 grows gradually and is pulled downward, by which the strip 7 is cast. For example, two sets of intermediate partition plates parallel with side seals 2b are fixed within the flask 2 constituted of barrel seals 2a and the side seals 2b to trisect the inside of the flask 2. The temp. of the molten metal to be poured to the specific divided part of the mold is made higher than the temp. of the molten metal to be poured to the other divided parts of the mold. |
