摘要： A cooling section for flat rolling stock has a working region, through which the flat rolling stock is guided. The working region can be supplied with a liquid coolant by means of a number of spray beams. The liquid coolant is fed from a reservoir for the liquid coolant to the spray beams by means of a pump and a supply system. Valves are arranged upstream of the spray beams in the supply system. Opening positions of the valves are set by a control unit of the cooling section according to a respective sub-flow that is to be applied to the flat rolling stock by means of each spray beam. Also, the delivery rate of the pump and/or a line pressure generated by the pump in the supply system are set by the control unit according to the total flow that is to be applied to the flat rolling stock by means of all the spray beams.

摘要： A method for producing a metal strip, in which the strip is rolled in a multi-stand rolling mill, is removed behind the final rolling stand of the rolling mill in the direction of conveyance, and is cooled in a cooling device. The strip or metal sheet is subjected to additional rapid cooling immediately after passing the working rollers of the final rolling stand, wherein the strip or the metal sheet is cooled at least partially within the extent of the final rolling stand in the direction of conveyance, wherein rapid cooling is performed by applying a coolant to the strip or metal sheet from above and from below, wherein the volume flow of coolant that is applied to the strip or metal sheet from below measures at least 120% of the volume flow of coolant that is applied to the strip or metal sheet from above.

摘要： A plurality of water removing nozzles of a water removing apparatus comprise one or more of a single far water removing nozzle and a far water removing nozzle group. The single far water removing nozzle forms a far end water removal single area that does not include one end but includes the other end in the width direction of a steel sheet conveyance plane. The far water removing nozzle group forms the far end water removal single area and one or more inner water removal single areas that do not include either end in the width direction of the steel sheet conveyance plane, in such a manner that the far end water removal single area and the one or more inner water removal single areas are aligned in order from the one end side to the other end side while overlapping with each other in the width direction of the steel sheet conveyance plane and aligned in order from the upstream side to the downstream side without overlapping in the conveyance direction.

摘要： A method for manufacturing a steel sheet of the invention includes a hot-rolling process in which a steel material is hot-rolled using a finishing mill so as to obtain a hot-rolled steel sheet; and a cooling process in which the hot-rolled steel sheet is cooled. The hot-rolling process includes a target steepness-setting process in which a target steepness of the edge wave shape is set based on first correlation data indicating a correlation between a steepness of the edge wave shape of the hot-rolled steel sheet and a temperature standard deviation Y; and a shape-controlling process in which operation parameters of the finishing mill are controlled so as to match the steepness of the edge wave shape with the target steepness.
