METHOD FOR PRODUCING HOT-ROLLED STRIPS IN A CONTINUOUS CASTING MACHINE AND WIDE STRIP MILL METALWORKING COMPLEX

摘要

It is proposed, during casting in a continuous casting machine, to produce slabs of identical length but different thicknesses and, during deformation of these slabs in a roughing train or a reversing roughing stand, to lessen reduction in the roughing passes, according to the reduction in thickness of the slabs supplied for rolling, to the point of completely excluding the first roughing stands from the deformation of the slabs or of reducing the number of passes in the reversing roughing stand. The length of the cast slabs is equal to the maximum length of the slabs that the wide strip mill is designed to roll, while the thicknesses of slabs of identical width are determined by the mass of the coils produced therefrom.
