VERFAHREN ZUR HERSTELLUNG WARMGEWALZTER HOHLPROFILE MIT RECHTECKIGEM QUERSCHNITT UND MIT KLEINEN KANTENRADIEN
In a method for producing hot-rolled sections of steel with a rectangular or square cross-section, a substantially round pipe blank produced seamlessly by hot rolling or cold finished and welded and having a defined nominal outside diameter is initially produced and then formed at a forming temperature into a hollow section having the required cross-section, with visible edges C1 and C2 of the hollow section having a value ≰1.5×t (t=wall thickness). The pipe blank has a nominal outer diameter determined from a reduction ratio of the pipe blank to be achieved and the hollow section dimensions to be achieved, wherein the reduction ration lies within a range of −2% to −13% and is determined according to the following formula: Reduction ratio R[%]=[(2×(H+B))−π×D]×100%/[2×(H+B)].
