| 摘要 |
The invention proposes that, by successive process steps, lightweight structural steel with a predetermined chemical composition of up to 27% Mn, 1 to 6% Al, 1 to 6% Si, < 0.8% C, remainder Fe and accompanying elements, be cast on a thin-slab casting I machine (1) (d?120 mm) using suitable casting powders, then immediately after the solidification slabs (3) be severed from the endless strand (2) and that temperature equalization be carried out during continuous passage through an intermediate furnace (4) and then the slab (3) be directly hot-rolled without intervening cooling.
