Abstract (en)
[origin: WO0005422A1] The invention relates to the production of dual-phase steel (2) which is obtained by targeted cooling after the final deformation step in a rolling stand (1), whereby a dual-phase structure of between 70 and 90 % ferrite and between 30 and 10 % martensite is adjusted. So as to be independent of steel geometry and strip speed the invention provides for cooling to take the form of fluidized-bed cooling carried out in a cooling line (6) comprising water-cooling stages (7) arranged one behind the other.
