Abstract

PURPOSE:To double the output per hour by producing a slab of a double width by continous casting or blooming, cutting slits thereto and producting plural steel strips of a standard width. CONSTITUTION:A slab 1 is produced to have the width twice larger than a standard width by continuous casting or blooming, and this double width slab 1 is cut in the longitudinal direction of the slab by leaving a part of the slab thickness in the position where the prescribed width of steel strips is obtained. More specifically, the slab is cut from the front or rear side and is formed with slit grooves by leaving a part of the slab thickness. This grooved double width slab is charged into a heating furnace and is heated to prescribed temp., after which it is subjected to rough rolling and finish rolling with continuous hot rolling mills, whereby a steel strip 4 is produced. This is taken up as a steel strip coil 4. This coil 4 is divided to plural steel strips with shearing rolls 5, after which the strips are taken up.
