Abstract

The invention relates to a production method for producing, on a production installation (1), flat products, also of a large width, from continuously cast slabs having a large or medium thickness or from thin slabs. Said production installation is comprised of a single or multiple stand blooming train (4), of a roller table (3), which is provided for conveying the rolling stock and, optionally for oscillating, of a roller table section (5) with hinged heat-insulating covering hoods. The production installation is also comprised of a straightening unit (6) for straightening the pre-strips, of an, in particular, inductive heating installation (7) for effecting the controlled heating of the pre-strips to a defined temperature over the length and width of the pre-strips, of a multiple-stand finishing train (10), of a delivery roller table with devices (11) for cooling the hot rolled strip, and of subsequently arranged coiling machines (12) for coiling the finished strip. In the single or two-stand blooming train (4), one or more slabs comprised of carbon steels having an average carbon content of approximately 0.2 to 0.8% or of alloyed case hardening steels or heat-treatable steels are…
