ABSTRACT:
A continuously cast steel strip which consists of a solidified casting shell and a liquid core is reduced in thickness in a roll deformation and is then rolled. In order to avoid undesired fluctuations in thickness, to improve the structure and to simplify the roll deformation unit, a steel strip billet of 40-80 mm thickness is cast, roll deformed to 15-40 mm thickness having a 2-15 mm residual liquid core in a maximum of three steps. The roll deformed billet is then guided to complete solidification.
