Description
The utility model relates to a kind of coil of strip coreless feeding type Coil Box, and it is arranged between thick, the finishing mill on the hot-rolling line, is used for middle made-up belt carried out in machine that centreless batches, oppositely uncoiling and centreless is transferred and insulation unreels.
Traditional hot-rolling line, because middle made-up belt length is longer, the temperature difference that enters finishing mill end to end is bigger, for reducing the band steel toe tail temperature difference, adopts increasing speed rolling usually, or increases stay-warm case on the roller-way between thick, the finishing mill.Adopt increasing speed rolling, the main capacity motor of finishing mill line must increase about 30% to 40%, and adopts the stay-warm case form, increase energy consumption; For guaranteeing the finishing temperature of band afterbody, also must improve the tapping temperature of blank in addition, also will increase energy consumption.For addressing the above problem, applicant (China Second Heavy Machinery Group Co) has proposed preposition application-Coil Box, and Granted publication number is CN2377023Y.It discloses the Coil Box that a kind of frame is a frame structure.Though solved many problems, but when take-up, still there is the problem that influences product quality and output in following part-structure: the last bending roll of the described Coil Box of former patent and roller frame thereof are installed in the framework window of band loam cake, when replacing with down the bending roll parts, must remove loam cake and on a large amount of pressure ducts, both difficulties and time-consuming; The forming rolls roller frame pivot suspension cover of the described Coil Box of former patent is welded on the frame, in roll coil of strip coiling process, bears the enormous impact power from the roll coil of strip, the splicing sleeve damage that very easily is hit; No. 1 cradle roll oscillating roller frame axle sleeve of the described Coil Box of former patent is hinged on the stationary roll, the enormous impact power that axle sleeve produces when bearing roll coil of strip ellipse, and bearing connects high-strength bolt very easily to be broken, and changes frequently, has a strong impact on production; The transfer mechanism of the described Coil Box of former patent adopts plug to insert roll coil of strip endoporus and transfers and unreel, plug Long contact time roll coil of strip inner ring, not only cause inner ring made-up belt cooling blackout, make finished product band total length mechanical performance and gauge inconsistent, also make the plug temperature distortion; The transfer mechanism hydraulic permeability reversing gear flow of the described Coil Box of former patent is big, and the hydraulic system investment is big, and energy consumption is many; The described Coil Box of former patent is not provided with attemperator above No. 2 cradle rolls, the major diameter roll coil of strip is because the time that unreels is longer, and made-up belt flanging part temperature drop is big, causes the finished product band inhomogeneous in the width mechanical performance.
The purpose of this utility model is to solve the problem that the traditional hot continuous rolling technology exists, and on former patent structure basis, further perfect, design a kind of coil of strip coreless feeding type Coil Box that can overcome the problems referred to above effectively.
The purpose of this utility model is such realization: inlet guide groove, bending roll and roll gap adjusting device, forming rolls and cradle roll, uncoiler, stabilizer are installed on the frame, are installed on the sole plate by pushing away centreless transfer mechanism that winding apparatus, oscillating roller, stationary roll form and the flipper guide that has insulated wall, cotter pin; Cradle roll has a stationary roll and an oscillating roller that is promoted by hydraulic cylinder, and stationary roll is installed on the frame, oscillating roller is hinged on the frame; Cooperate the pushing away of centreless transfer mechanism of moving volume that an idler roller and the swinging mounting that is promoted by hydraulic cylinder on swinging mounting is installed on the winding apparatus with cradle roll, a stationary roll and two oscillating rollers that promoted by hydraulic cylinder also are housed in this mechanism.The flipper guide that is arranged on centreless transfer mechanism top is equipped with two push pedals, guide post and push-and-pull hydraulic cylinders of insulated wall, and be equipped with thereon be used to launch magnetic tape trailer, by the cotter pin of Driven by Hydraulic Cylinder.
Described bending roll is a bending roll up and down, its down bending roll be fixed on the frame, but two go up bending rolls and be installed on the swinging mounting, this support is hinged on the frame, the hydraulic cylinder that drives this support swing is suspended on the support.
The roll gap adjustment of described bending roll roll gap device is to realize by the position sensor of adorning in the bending roll hydraulic cylinder.
Described bending roll roll gap device is installed on the bending roll support, connect by synchronizing shaft by motor-driven two screw jack, the jack head all the time with frame on a fixed bearing plane keep in touch.
Described forming rolls is made of an idler roller and a lifting hydraulic cylinder that is installed on the swinging mounting, and this hydraulic cylinder is hinged on the frame.
The top of described cradle roll is provided with stabilizer, is cooperated by two push pedals that have guide rod and push-and-pull hydraulic cylinder.
Describedly on the uncoiler that is provided with above the stabilizer, be equipped with respectively, insert arm, insert the arm end uncoiling cutter is installed by the revoliving arm of slewing equipment and Driven by Hydraulic Cylinder.
Middle the made-up belt of the utility model Coil Box that adopts said structure after, import by deflection roll and to carry out coreless roll behind the bending roll and get, and assist by forming rolls and cradle roll and to finish roughing.Uncoiler is rolled up reverse opening with made-up belt, and making the made-up belt afterbody become head, to enter finishing mill rolling.Play the effect that is incubated soaking when not opening fully at the made-up belt volume, help reducing to be with the steel toe tail temperature difference, make the vertical mechanical performance uniformity of product band, and reduce the thickness difference of length direction.The centreless transfer mechanism is transferred to made-up belt volume to unreel the position and implement insulation and unreels from batching the position, is convenient to safeguard and eliminates made-up belt volume inner ring and limit portion temperature drop.After this Coil Box is set, shorten the bending roll repair time, the distance that can shorten between roughing mill and the finishing mill is about more than 1/2, has reduced the length of factory building and delay table.Therefore the utlity model has: improve the finished product strip quality, save advantages such as the energy and saving investment.
Be described in further detail below in conjunction with accompanying drawing.
