Abstract
The utility model discloses a flat cooling control device for a thermal mechanical rolling and cooling control steel sheet, which comprises a spray device. The device also comprises deformation control flattening roller sets which are symmetrically arranged on the upper side and the lower side. At least five sets of the deformation control flattening rollers are arranged at intervals. Each deformation control flattening roller set consists of an upper flattening roller device and a lower flattening roller device. The spray device is arranged above the upper flattening roller and/or below the lower flattening roller. As the device is simple in structure and the flattening cooling control device is adopted after the final rolling of the production flow of TMCP steel, the cooling rate of a TMCP steel sheet is controlled, and the steel sheet is flattened; and the deformation of the steel sheet is effectively controlled, the surface quality and the yield of the steel sheet are improved, and the benefit is obvious.
Description
Technical field
The utility model belongs to steel plate quality of production control technology, is specifically related to mechanical controlled rolling and controlled cooling steel plate cooling of a kind of heat and deformed Control Technology.
Background technology
In the steel rolling production process, in order to improve steel rolling production efficiency, reduce production process, reduce production costs, change a part of heat-treated steel plate into TMCP (hot mechanical controlled rolling and controlled cooling) steel plate and produce, reduced heat treatment step, can cut down the consumption of energy significantly, reduce production cost, enhance productivity, production capacity increases substantially simultaneously.But the TMCP steel plate that adopts prior art to produce often causes the plate property produced inhomogeneous, and defectives such as plate surface quality difference do not have flattening device to cause the surface of steel plate injustice in cooling procedure, are difficult to use.
Chinese patent ZL200520040592.6 provides a kind of " band steel continuous annealing high speed jet cooling facility for laminar flow ", Chinese patent ZL03212745.6 discloses a kind of " hot-strip intermediate blank cooling facility for laminar flow ", Chinese patent ZL 2,006 2,007 7622.5 has showed a kind of " Aldecor rolls the side-jetting of back cooling water and sweeps system ", Chinese patent Z L 2,006 2,016 6942.8 provides a kind of " hot rolled strip cooling facility for laminar flow ", Chinese patent ZL200720067925.3 discloses a kind of " the laminar flow cooling swing group with automatic drain function ", and Chinese patent ZL96211971.7 provides a kind of " Water Curtain Strip Laminar Cooling Device ".United States Patent (USP) 10/489,382 disclose a kind of " Method anddevice for cooling steel sheet ", United States Patent (USP) 10/046,106 provide a kind of " Method and apparatus for cooling hot rolled steel strip; and method for manufacturing hot rolled steel strip ", United States Patent (USP) provides a kind of 10/793,480 " Method and apparatus forcooling hot rolled steel strip, and method for manu-facturing hot rolled steel strip ".Listed patent steel rolling cooling device or auxiliary coolant system though have the control refrigerating function, all can not solve steel plate and problem on deformation occur in cooling procedure, and in fact, in producing TMCP steel plate process, invar plate gross distortion causes waste product, loses bigger.
Summary of the invention
The purpose of this utility model is to provide a kind of smooth controlled cooling device that can realize hot mechanical controlled rolling and controlled cooling steel plate cooling and Deformation control, to address the above problem.
The technical solution of the utility model is: the smooth controlled cooling device of hot mechanical controlled rolling and controlled cooling steel plate, it comprises spray equipment, it comprises that also the control that is oppositely arranged up and down is out of shape smooth roller group, control the smooth roller group of distortion at least 5 groups are set at interval, every group of smooth roller group of control distortion is made up of last smooth roller arrangement and following smooth roller arrangement; Described spray equipment is located at the below of smooth roller top and/or following smooth roller.
Described control is out of shape that smooth roller is provided with arrangement for adjusting height on the smooth roller group, and following smooth roller is not provided with arrangement for adjusting height.
Described adjacent control is out of shape between the smooth roller group and is spaced apart 150 millimeters.
Described spray equipment setting at least 5 rows, every row evenly is provided with at least 5 nozzles.
Described control is out of shape smooth roller group and is provided with upper and lower smooth roller arrangement arrangement for adjusting height.
Because the utility model is simple in structure, after producing the finish to gauge of TMCP steel flow process, adopt smooth controlled cooling device, not only controlled the cooldown rate of TMCP steel plate, but also smooth steel plate, effectively the distortion of control steel plate has improved plate surface quality and yield rate, remarkable benefit.
