Abstract: A method for the treatment of sheets which are rolled to final dimensions in a roll stand, subsequently undergoing on-line cooling, straightening and heat treatment for homogenization and influencing of microstructure. To improve the heat treatment, the heat treatment is carried out online such that it is decoupled from the preceding cooling and straightening, while taking into account the speed at which the sheet exits from the final workstation upstream, the time at which the heat treatment begins is selected in such a way that the sheet has completely left this final workstation before the sheet is subjected to the heat treatment.

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.

Abstract: The invention relates to a method for increasing the process stability, particularly the absolute thickness precision and the installation safety during the hot rolling of steel of nonferrous materials, with small degrees of deformation (f) or no reductions while taking the high-temperature limit of elasticity (Re) into account when calculating the set rolling force (Fw) and the respective setting position (s). The process stability can be increased with regard to the precision of the yield stress (kf,R) and the set rolling force (Fw) at small degrees of deformation (f) or small reductions, during which the high temperature limit of elasticity (Re) is determined according to the deformation temperature (T) and/or the deformation speed (phip) and is integrated into the function of the yield stress (kf) for determining the set rolling force (Fw) via the relation (2) Re=a+eb1+b2·T.phipc, in which: Re represents the high temperature; phip represents the deformation speed, and; a, b, c represent coefficients.

Abstract: The invention relates to a device for producing a metallic product (1) by rolling, comprising: a first area (2) inside of which slabs are produced by primary shaping; a second area (3), which is located downstream from the first area (2) in the direction of flow (F) of the material and inside of which at least one first rolling device (4) for rolling slabs is arranged; a third area (5), which is located downstream from the second area (3) in the direction of flow (F) of the material and inside of which at least one second rolling device (6) for rolling slabs or the intermediate product produced therefrom is arranged, and; a fourth area (7), which is located downstream from the third area (5) in the direction of flow (F) of the material and inside of which at least one aftertreating device (8) for the rolled material is arranged.
