A method for coiling a metal strip that is heat-treated in a furnace immediately before coiling and fed to a coiler at an outlet speed, and then coiled at the coiler at an elevated temperature. The future outlet speed of the metal strip and the heat losses from the metal strip between the furnace and the coiler are calculated via a predictive model and the furnace is controlled by the predictive model such that the metal strip is coiled at a pre-defined temperature within a maximum deviation of +/5 C.

Disclosed is a tubular core on which sheets of metal or other material can be wound and supported, for shipment, handling and dispersal, and a method for forming the core. The core comprises a metal sheet or strip which has a rectangular-ribbed cross-sectional profile comprising rectangular, flat ribs, and which is wound spirally into a tubular configuration. The core is formed by passing the strip through a plurality of roll-forming stands, to progressively form sections of the ribs and progressively define the sections into the rectangular ribbed profile in which the flat ribs collectively form a support surface for the sheets which are to be wound on the core.

The present disclosure discloses a steel strip coiling temperature control method, a steel strip coiling temperature control device and a steel strip processing system, which relate to the technical field of steel strip production. The method comprises: seeking a corresponding speed compensation coefficient according to a target thickness of the steel strip and a target temperature parameter; seeking a corresponding speed gain coefficient from a second correspondence table according to a steel strip speed; correcting the steel strip speed based on the speed compensation coefficient and the speed gain coefficient to obtain a corrected steel strip speed; and adjusting a cooling efficiency of a laminar flow cooling apparatus according to the corrected steel strip speed. With the method, the cooling efficiency of the laminar flow cooling apparatus can be dynamically adjusted according to the steel strip speed, thereby solving the problem that that there is a great difference in coiling temperature between a tail section of the steel strip and a front section of the steel strip caused by the steel strip throwing process, and reducing the amount of cutting loss of the steel strip.
