Abstract
PURPOSE:To achieve the reduction in slab conveyance time and the miniaturization of rolling equipment by performing the pressing of the leading end of slabs independently from the rolling of the preceding slab and performing the working of the trailing end after ending of the rolling at the time of the final pass of the preceding slab. CONSTITUTION:The leading end part of a slab 1 is taper-worked by means of the pressing tools 10, 10' of a pressing machine 12 after which the slab 1 is moved and its trailing end part is taper-worked. The slab 4 after the working is sent to broadside rolling mills 16, whereby it is reduced broadside in several passes. On the way of the broadside rolling of the preceding slab, the leading end of the slab 1 is taper-worked and the slab is let to wait for a while. Right after the starting of the final pass rolling of the preceding slab 4 or at the ending of the final pass rolling, the next slab 1 is conveyed and the trailing end part thereof is taper-worked, thence the slab is sent to the broadside rolling mills 16. Thereby, the space between the pressing machine 12 and the broadside rolling mill 16 is made about one slab length and the equipment as well as buildings etc. are made smaller in size.
