摘要： As sections of a rolled product (1) pass through a cooling path (2), they are initially cooled in a first cooling phase by front cooling devices (6). The sections are then not cooled in a subsequent second cooling phase. They are finally cooled again in a subsequent third cooling phase, by rear cooling devices (8) of the cooling path (2). A control device (10) of the cooling path receives in each case an initial energy value (EA) exhibited by the sections before they pass through the cooling path (2). The control device furthermore receives a target energy (El *) and a target enthalpy (E2*). The control device (10) determines a first target cooling medium profile (K1 *) on the basis of the initial energy value (EA) and the target energy (E1 *). The control device controls the front cooling devices (6) in accordance with the first target cooling medium profile (K1 *) while the respective section is passing through the front cooling devices (6). The control device (10) determines a second target cooling medium profile (K2) on the basis of an expected enthalpy for the respective section in the second cooling phase and the target enthalpy (E2*). The control device controls the rear cooling devices (8) in accordance with the second target cooling medium profile (K2*) while the respective section of the rolled product (1) is passing through the rear cooling devices (8).

摘要： A method for descaling a metal strip, in which the metal strip is guided in a direction of conveyance through at least two plasma descaling units, in which it is subjected to a plasma descaling, where the plasma descaling is followed directly or indirectly by an operation in which the metal strip is coated with a coating metal by hot dip galvanizing of the metal strip. The metal strip is coated with the coating metal by a vertical passage process. The coating metal is retained as a coating bath in a coating tank by an electromagnetic seal. The metal strip preheated by the plasma descaling is guided, without exposure to air, from the plasma descaling into a protective gas atmosphere of a continuous furnace necessary for the coating.

摘要： The invention relates to a method for hot-rolling a slab (1), especially a steel slab, the slab (1) being subjected to at least two shaping steps at different temperatures in a hot-rolling mill (2), the slab (1) being cooled between two such shaping steps. In order to prevent ferrite from forming too soon during the hot-rolling, the slab (1) is cooled such that the lateral end sections (3, 4) of the slab (1) are cooled with a lower cooling efficiency than a center section (5) of the slab (1). The invention further relates to a hot-rolling mill (2) for hot-rolling a slab.

摘要： The present disclosure relates to a hot rolling apparatus for manufacturing a metal plate by hot-rolling-treating a metal material including copper. The apparatus includes: a rough rolling device for rolling-treating the metal material, which has been heating-treated, a plurality of times with a back-and-forth movement of the metal material, to mold the metal material into a metal plate; a heat retention/application treatment device for retaining heat of or applying heat to the metal plate molded by the rough rolling device at lower temperatures than in the heating treatment, without applying bending; a finish rolling device for further rolling-treating the metal plate that has been heat-treated by the heat retention/application treatment device; a cooling device for cooling the metal plate that has been rolling-treated by the finish rolling device; and a support table for movably supporting the metal plate from below before and after the rough rolling device while the metal material is moved back and forth by the rough rolling device. According to the present disclosure, it is possible to improve the quality of the metal plate manufactured in the hot rolling apparatus, and also to improve the speed of the process required for rolling.
