Abstract
The utility model discloses a collocation method of a vertical mill in a hot strip mill set, which comprises a horizontal roll roughing mill, and is characterized in that one vertical mill is respectively allocated at the front end and the back end of the horizontal roll roughing mill. Neighboring racks are connected with each other tightly by connecting bolts and taper keys between each vertical mill and each horizontal roll roughing mill; and a uniformly designed rolling mill platform, a leading-in device and a rack are arranged. The utility model changes the former type of universal rolling mill into a combined type, thus realizing full-gate hot rolling and supplying the new method for plate shape control and quantity control of products.
Description
Technical field
The utility model relates to the job sequence of roughing district vertical miller in the hot continuous rolling unit, relates in particular to the order of mill train, and the associating that is intended to make each passage all can realize vertical miller and horizontal roller roughing mill is rolling.
Background technology
Along with rapid development of national economy, industry-by-industry is increasing to the demand of hot-strip, and the product quality of hot-strip and the requirement of specification are also got more and more.In the face of the competition in hot-strip market, the width quality control of hot strip steel product is had higher requirement, must in links such as crop, back-end crop and side cut, obtain higher volume ratio, cost is reduced, improve Enterprises'Competitiveness.Continuous development along with rolling technique, width of plate slab is controlled automatically, slab Head and Tail Shape control (short stroke control), and it is also progressively ripe to set up advanced technologies such as parting power control a little between the same level milling train, vertical miller installation level also is able to continuous raising, thereby has improved the volume ratio in the production process effectively.
But in present hot continuous rolling production line, on arranging, still adopts by the home and abroad vertical miller horizontal roller roughing mill stand-alone configuration before, with the form of the synthetic universal mill of horizontal roller roughing mill.This arrangement form can only realize that strange passage vertical miller and horizontal roller roughing mill carry out tandem rolling, and when even passage is rolling, because slab must be introduced into horizontal mill, and it is normally rolling voluntarily to enter vertical miller, so, have only horizontal mill to work independently in even passage, can't carry out width control slab.What is worse, if the slab specification changes, as adopting the slab of Anshan iron and steel plant 2150 units, thickness has only 135mm, and during less than normal slab thickness 230mm, the roughing passage reduces, only wide rolling by strange road secondary control, then can't satisfy arts demand, also can't satisfy the quality requirement of sheet material naturally.
Summary of the invention
Goal of the invention of the present utility model is to overcome targetedly shortcoming of the prior art, changes the mill train order by vertical miller being become forward and backward the layout simultaneously of horizontal roller roughing mill, thereby realizes the full passage tandem rolling of vertical miller and horizontal roller roughing mill.
Technical solution of the present utility model is achieved in that
The configuration mode of a kind of vertical miller in the hot continuous rolling unit comprises a horizontal roller roughing mill, it is characterized in that: the front and back ends at the horizontal roller roughing mill disposes inlet vertical miller and outlet vertical miller respectively; Inlet vertical miller and outlet vertical miller are all by attachment bolt and wedge key will enter the mouth vertical miller frame and horizontal roller roughing mill frame and export the vertical miller frame and fixedly connected with horizontal roller roughing mill frame, make described vertical miller and horizontal roller roughing mill form close-coupled tandem rolling structure, unified milling train platform, breast roll and rolling mill guide also are housed on described frame.
Described milling train platform is by outlet vertical miller platform, and inlet vertical miller platform and horizontal roller roughing mill platform are formed.
Compared with the prior art, the utility model has the advantages that conspicuously, mainly show, realize the width of plate slab control of full passage by changing the configuration mode of existing hot continuous rolling unit, controlled the quality of slab limit portion effectively, the production flexibility that has improved rolling line simultaneously.
Description of drawings
The utility model drawings attached 5 width of cloth, wherein:
Fig. 1 is a structural representation of the present utility model;

Among the figure: 1 slab, 2 inlet vertical millers, 3 horizontal roller roughing mills, 4 outlet vertical millers, 5 inlet vertical miller frames, 6 horizontal roller roughing mill frames, 7 outlet vertical miller frames, 8 attachment bolts, 9 wedge keys, 10 outlet vertical miller platforms, 11 inlet vertical miller platforms, 12 horizontal roller roughing mill platforms, 13 go into, export the vertical miller guide plate, and 14 go into, export horizontal roller roughing mill guide plate, 15 breast rolls, 16 bottom guides, 17 breast rolls.
The specific embodiment
The configuration of a kind of vertical miller in the hot continuous rolling unit shown in Fig. 1,3,4 and 5 comprises a horizontal roller roughing mill, and its front and back end has been arranged a vertical miller respectively, as shown in Figure 1.This arrangement form home and abroad vertical miller arrangement form more in the past is very different.Vertical miller in the past is to be arranged in horizontal roller roughing mill the place ahead, is combined into a universal mill with the horizontal roller roughing mill, as shown in Figure 2.This arrangement can only realize that strange passage vertical miller same level roller roughing mill carries out tandem rolling, and when even passage is rolling, because slab is introduced into the horizontal roller milling train, cause the vertical miller can't be normally rolling, so have only the horizontal roller roughing mill to work independently in even passage, can't realize the bad width that carries out of plate is controlled.And when the bad supplied materials thickness of plate during less than normal supplied materials thickness, in fact production line roughing passage is lacked than normal passage.If only adopt strange road secondary control wide rolling, then can not satisfy arts demand.And the utility model has just solved the problems referred to above well on arrangement form, has realized that each rolling pass all can realize width control to slab.Thereby the quality of edges of slab and the width of slab have more effectively been controlled.
In order to realize the arrangement of this utility model, taked following measure from device structure:
(1). as Fig. 3, inlet, outlet vertical miller frame 2,4 and horizontal roller roughing mill frame 6 are fixedly connected by attachment bolt 8, wedge key 9 and form the close-coupled connected mode.
(2). as Fig. 4, inlet, outlet vertical miller platform 11,10 and horizontal roller roughing mill platform 12 are unified in design arranges that it is little to have overcome the space, the problem that pressure system can't be put.
(3). as Fig. 5, will enter the mouth, export vertical miller and the unification of horizontal roller roughing mill has designed slab gatherer 13,14, occur the steel-fastening phenomenon when preventing the slab tandem rolling.
(4). as Fig. 5, will enter the mouth, export vertical miller and the unification of horizontal roller roughing mill has designed breast roll device 15,16,17, cause the accident because of being short of power at device interior when preventing the slab tandem rolling.A series of problems such as rolled piece importing, derivation and the screwdown gear placing space deficiency brought because of compact conformation and equipment pipe arrangement insufficient space have also been overcome simultaneously.
