METHOD FOR PRODUCING A HOT-ROLLED STEEL STRIP AND COMBINED CASTING AND ROLLING INSTALLATION FOR CARRYING OUT THE METHOD

摘要

A method for the production of a hot-rolled steel strip from a steel melt in a continuous manufacturing process: continuously casting a steel strand in a continuous casting mold of a continuous casting plant, roll-forming the case steel strand in a first group of roll stands into a pre-rolled hot strip, roll-forming the pre-rolled hot strip in a second group of roll stands into a hot-rolled steel strip, setting the hot strip to a rolling temperature between the first and second groups, and winding or dividing the hot-rolled steel strip; further: descaling the hot strip before temperature setting, holding the hot strip in a protective gas atmosphere during temperature setting. A combined casting and rolling plant for the method is disclosed.
