摘要

Continuously cast slabs production comprises using device having blooming train (4), roller table (3) for transporting rolled material, roller table section (5) with hoods, unit for leveling pre-strips, inductive device (7) for heating pre-strips to defined temperature, finishing train (10), delivery roller table with devices for cooling hot strip and coiling machines for coiling finished strip. One or more slabs made of carbon steel containing 0.2-0.8% carbon are rolled to pre-strips in the blooming train. The pre-strips are heated to a defined temperature using the combined action of the hood and the heating device, and then rolled. The rolling temperature lying in the upper austenite region in the first deformation stage in the blooming train leads to a conversion of a continuous cast structure to a rolled structure by complete recrystallization. An independent claim is also included for a device for carrying out the process.
