A method for the production of a hot-rolled steel strip from a steel melt in a continuous manufacturing process, with an uninterrupted strip runthrough, comprising continuously casting a steel strand in a continuous casting mold of a continuous casting plant, roll-forming the cast steel strand in a first group of roll stands into a pre-rolled hot strip, further roll-forming the pre-rolled hot strip in a second group of roll stands into a hot-rolled steel strip, setting the pre-rolled hot strip to a rolling temperature between the first group of roll stands and the second group of roll stands in a temperature setting device, and winding of the hot-rolled steel strip into bundles or the division of the hot-rolled steel strip into sheets. In order to increase flexibility in the production of different steel qualities and to keep investment costs and operating costs low, descaling the pre-rolled hot strip immediately before its entry into the temperature setting device, holding the pre-rolled hot strip in a protective gas atmosphere in the temperature setting device, and after the pre-rolled hot strip runs through the temperature setting device, roll-forming the strip immediately thereafter in the second group of roll stands. Further, a combined casting and rolling plant for carrying out the method is disclosed.
