The specific embodiment
Be elaborated below in conjunction with the specific embodiment of accompanying drawing to the utility model.Should be understood that the specific embodiment described herein only is used for explanation and explains the utility model, is not limited to the utility model.
In the utility model, under the situation of not doing opposite explanation, the noun of locality of use like " front, back, left, right, up, down " normally to the throughput direction of rollgang or rollgang.
As shown in Figure 2; And combine Fig. 3 to Fig. 7 visible; The utility model provides a kind of ultrafast cooling system of hot rolling line, this ultrafast cooling system comprises rollgang 1 and water injector, and this ultrafast cooling system also comprises the roller-way side plate 2 that is arranged on said rollgang 1 both lateral sides; This said rollgang 1 in roller-way side plate 2 upper edges vertically be formed with a plurality of delivery ports 3, vertical formation acute angle angle of the Way out p of this delivery port 3 and said rollgang 1.Wherein, Rollgang 1 vertically be the throughput direction (being drive motors 7 orientations among Fig. 2 or the roller-way throughput direction that Fig. 4, Fig. 6 indicated) of rollgang; Rollgang 1 laterally be the lateral (being the direction of drive motors 7) of rollgang 1 with respect to rollgang 1, the Way out p of delivery port 3 promptly in the roller-way side plate 2 to the ponding of the outer outflow outflow direction during through delivery port 3.In the technique scheme; As total design; The delivery port 3 (shown in Figure 3) of vertical formation acute angle angle of setting and rollgang 1 on roller-way side plate 2; Thereby draining in time, avoid cooling water with water injector ejection via the hot rolling part after the direct jet flow of formed ponding to the vertical vertical drive motors 7 of rollgang 1 on.Said acute angle angle is angle a shown in Figure 7, and when this angle was the right angle, then the Way out p of delivery port 3 was over against drive motors 7.Therefore, perpendicular to the roller-way throughput direction, promptly over against drive motors 7, the water capacity of then discharging from delivery port is prone to be splashed on the drive motors, thereby inadvisable as if delivery port 3.
Can avoid the delivery port 3 of drive motors 7 for forming above-mentioned Way out; As shown in Figure 2; Said roller-way side plate 2 preferably includes frame 21; Be provided with in this frame 21 along the polylith deflector 22 of vertical distribution of said rollgang 1, said delivery port 3 is formed between the adjacent said deflector 22, and is as shown in Figure 3.That is to say that plane roller-way side plate 2 has opening, the some plates of difference in opening; These some plates do not seal said opening, but leave the slit between the plate in twos, to form delivery port 3; Shown in Figure 3, deflector 22 lower ends wherein can be welded on the frame 21 fixing.And said polylith deflector 22 is preferably spaced set in parallel to each other, forms the barrier shape; As shown in Figure 4, wherein indicated the part of the polylith deflector 22 in the frame 21 with dotted line, visible from Fig. 4; Polylith flat board among the figure equally spaced is provided with; Form delivery port between flat board, change direction via deflector 22 when ponding is discharged, along the direction outflow of deflector 22.
In this embodiment, said deflector 22 is preferably flat board and forms the plane included angle a of 40-60 degree with said frame 21 planes, and is as shown in Figure 7.At angle is in the scope of 40-60 degree the time, and ponding changes direction and is unlikely to too big or too lofty, causes impeded drainage, and ponding can be discharged on the basis that is not splashed to drive motors swimmingly.In addition, said deflector 22 can also be other shapes such as curved slab, repeats no more at this.
From Fig. 2 and shown in Figure 3, a side of said deflector 22 is fixed in said frame 21, and opposite side stretches out towards the direction opposite with the throughput direction of said rollgang 1.That is, the lower end of a side of deflector 22 shown in Figure 3 is fixed on the frame 21 with for example welding manner, and opposite side then tilts to extend outward with above-mentioned plane included angle a, just drainage direction.The bearing of trend of wherein said deflector 22 opposite sides is in contrast to the throughput direction of rollgang 1, can help avoid hot rolling part said deflector 22 of damage when on rollgang 1, carrying.
Like Fig. 5 and shown in Figure 6, shown the front view and the A-A cutaway view of the ultrafast cooling system that is used for hot rolling line of the utility model respectively, front view wherein i.e. the view towards roller-way side plate 2 direction projections from drive motors shown in Figure 27 positions.Visible from figure, the said water injector in the utility model comprises the upper header 4 and lower collector pipe 5 that is separately positioned on said rollgang 1 above and below, and this upper header 4 is provided with relative nozzle 6 with lower collector pipe 5.Under the duty as shown in Figure 5, towards the upper and lower surfaces ejection cooling water of the hot rolling part that pass through rollgang 1, by discharge outlet 3 discharged again respectively by cooling water for the nozzle 6 on upper header 4 and the lower collector pipe 5.In addition, this ultrafast cooling system also comprises some drive motors 7, and said some drive motors 7 are spaced apart and arranged in vertically arranging of the said rollgang 1 in said roller-way side plate 2 outsides and edge, and roller-way side plate 2 can be installed on the sole plate through bolt.Wherein, The upper surface of the said rollgang 1 of nozzle 6 distances that said lower collector pipe 5 is positioned at below and the said lower collector pipe 5 of said rollgang 1 is preferably less than 50mm; And said upper header 4 is positioned at the upper surface of the said rollgang 1 of nozzle 6 distances of top and the said upper header 4 of said rollgang 1 and is preferably less than 700mm; To guarantee to be ejected into the hydraulic pressure and the water speed of the surperficial current of hot rolling part, can also strengthen the cooling velocity and the cooling effect of ultrafast cooling system simultaneously.
The ultrafast cooling system that is used for hot rolling line of the utility model possesses efficiently, stable and safe drain function, realizes unimpeded draining through the mode that deflector is set simplely.So not only solve ponding and discharged the cooling effectiveness low problem when smooth, can also improve the structure property and the surface quality of hot rolling part, and surface and the flatness defect such as " blackspot " or wooden dipper song for example of generation still less.
More than combine accompanying drawing to describe the preferred implementation of the utility model in detail; But; The utility model is not limited to the detail in the above-mentioned embodiment, in the technical conceive scope of the utility model, can carry out multiple simple variant to the technical scheme of the utility model; For example; Can adopt other version except that above-mentioned deflector to form the delivery port of inclination, perhaps said deflector is other shapes such as arc, and these simple variant all belong to the protection domain of the utility model.
