    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: The invention is directed to a device for straightening a stream of a cooling medium for cooling a roll or a metal strip. This device comprise a hollow body, extending over at least part of the width of the roll or the metal strip, and a tube, arranged in the hollow body and extending in the direction of the width of the roll or the metal strip, wherein the hollow body is divided in the direction of the width of the roll or the metal strip into a number of chambers, and the tube comprises openings for introducing cooling medium into the chambers of the hollow body, and the chambers respectively comprise an opening for the flowing out of cooling medium from the hollow body. Furthermore, according to the invention the chambers, respectively, comprise a channel, formed between the inner wall of the hollow body and the tube, for conducting cooling medium from the openings of the tube to the opening for the outflow of cooling medium from the hollow body, wherein the flow cross-section of the channel narrows art least at its downstream end.

    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.
