The invention relates to a texturing roll rolling system and method of a UCMW tandem cold rolling mill. The texturing roll rolling system and method of the UCMW tandem cold rolling mill comprises a rolling mode identity module, a basic setting and calculation module, a texturing roll constant-rolling-force setting module, a No.5 rack reduction ratio setting module and a rolling control system, wherein the rolling mode identity module is used for judging a roll mode; the basic setting and calculation module is used for obtaining required rolling parameters from a reduction ratio constant table corresponding to the texturing roll mode; the texturing roll constant-rolling-force setting module is used for calculating rolling force in the texturing roll mode according to the type, the width and thickness specifications and the rolling speed of strip steel; the No.5 rack reduction ratio setting module is used for selecting No.5 rack reduction ratio from the reduction ratio constant table corresponding to the texturing roll mode according to the type and the width and thickness specifications of a set steel coil. The invention additionally relates to a method using the system. The rolling system and the method provided by the invention have the advantages that the rolling mill can realize stable rolling in the texturing roll mode, the shape and dimension accuracy of finished strip steel plates can be guaranteed and especially the surface quality of the strip steel can be guaranteed.

The invention relates to a laminar flow width-adjusting cooling device and a control method thereof. The laminar flow width-adjusting cooling device comprises a plurality of groups of spray pipe devices, and each group of spray pipe device comprises a collecting pipe, a screw rod and two pistons, wherein the middle part of the collecting pipe is provided with a water inlet pipe, and the collecting pipe is provided with a plurality of spray pipes which are evenly distributed; the screw rod is arranged in the center of the collecting pipe along the axial direction; and the two pistons are respectively arranged on the screw rod and can move in the collecting pipe along the length direction of the screw rod, and the external diameters of the pistons are matched with the internal diameter of the collecting pipe. According to the requirements of the cooling technique of the strip steel with different widths, the invention can be used for adjusting the area of cooling water along the width direction of a channel, thus reducing the temperature reduction of the side of the strip steel, and ensuring the uniformity of the profile shape, the mechanical performance, the temperature and the phase change of the strip steel along the width direction.

The invention relates to a laminar flow cooling upper spray blocking device which comprises a plurality of groups of lower spray devices, and each group of lower spray device comprises a collecting pipe, a plurality of spray pipes, at least one screw rod, two sliding blocks and two blocking plates, wherein the spray pipes are evenly distributed on the collecting pipes; the at least one screw rod is arranged at the upper part of the collecting pipe in a spanning way along the length direction of the collecting pipe; the two sliding blocks are provided with internal screw and are respectively connected with the screw rods by screw thread; the two blocking plates are respectively fixed with the sliding blocks, extend to an outlet of the collecting pipe; and the collecting pipe is movably shielded by a sliding mechanism. The laminar flow cooling upper spray blocking device can correspondingly build lower spray gap laminar flow corresponding to the width of a belt material channel according to the requirements of the cooling technique of the strip steel with different widths, and reduces the temperature reduction of the side of the strip steel by the corresponding change of a laminar flow cooling area along the width direction; and by adopting automatic lubrication, the device has the structure which is convenient for maintenance, and ensures the uniformity of the profile shape, the mechanical performance, the temperature and the phase change of the strip steel along the width direction.
