PURPOSE:To produce slabs having a desired width at a good yield and high speed by producing a broad and thin walled slab by a drum type continuous casting method and cutting online the slab to plural pieces in the transverse direction. CONSTITUTION:The slab 4 which is formed between drums 1, 1 and side gates 2 and is supported by guide roll 6 groups is parted to plural pieces of slab products 8 in a drum type continuous casting method for producing thin steel sheets. The slab 4 is produced by using about 8m broad drums as compared to ordinary about 2m drums. End parts 9 are removed by the prescribed width in the stage of parting the slab by cutters 7. The high-speed production of the slabs having the desired width at a good yield is thus made possible. |
