Description
Technical field
The utility model relates to the granulating unit field in steel pipe modifier treatment process, relates in particular to spray apparatus in a kind of steel pipe water quenching.
Background technology
In the modifier treatment process of steel pipe, shrend is an important step, and the quality of shrend has extremely important impact to the final heat treatment performance of product.At present, shrend both at home and abroad mainly contains following several mode: 1. flood; 2. dipping adds interior axial injection; 3. outside surface laminar flow sprays; 4. outside surface laminar flow is cooling adds interior axial injection.Wherein, the cooling cooling performance that adds interior axial injection of outside surface laminar flow is best.
At present, it is cooling that steel pipe's production enterprise generally adopts in steel pipe water quenching as shown in Figure 1 spray apparatus to carry out interior axial injection, and this interior spray apparatus is generally taper or pyramidal structure partially, and pyramidal structure is mainly in order to facilitate the centering of nozzle and steel pipe partially.As shown in Figure 1, in this interior spray apparatus, be provided with through hole 6, interior spray apparatus comprises first end 1, the second end 3 and the sidewall 2 between first end 1 and the second end 3, first end 1 is for being connected with water-supply line, and the second end 3 is for being adjacent to steel pipe and jet of water being entered to steel pipe so that cooling to steel pipe.For preventing that water coolant from spilling, be positioned at the water outlet aperture of the second end 3 conventionally than the little 20-40mm of pipe diameter.Adopt the interior spray apparatus of this structure to there is following shortcoming:
1, steel tube end part is cooling not good
As shown in Figure 2, due to taper/partially guide effect of tapered sidewalls, water coolant is contraction schedule during by the water outlet ejection of interior spray apparatus, and this can cause the steel pipe 9 ends water that can not be cooled completely to cover, and causes steel pipe 9 straight-line hardenings insufficient.
Under certain cooling water flow, for small dimension steel pipe, interior spray apparatus water outlet aperture is little, and water coolant flow velocity is fast, and water coolant can be full of fast whole steel pipes and compensate to steel tube end part, therefore steel tube end part quenches, insufficient problem is relatively slight; And for large specification steel pipe, water coolant is difficult to be all full of steel pipe, steel tube end part can not get water coolant compensation, and steel tube end part insufficient problem of quenching is serious.
2, large gauge steel inside pipe wall inhomogeneous cooling is even
When large specification steel pipe is quenched, the water outlet aperture of interior spray apparatus is large, and in the situation that cooling water flow is certain, water coolant flow velocity is low.Now, water coolant can not in time, fully be filled whole steel pipe inner wall, can cause steel pipe integral performance inconsistency larger.

Preferably, described sidewall surrounds truncated cone-shaped.
Preferably, the tapering of described round platform is identical with the tapering of described taper guide way.
Preferably, the area of described taper guide way bottom surface is and the 20%-50% of described bottom surface in conplane described via area.
Preferably, described a plurality of dividing plate is uniformly distributed along the circumferential direction of described through hole.
Preferably, described dividing plate is vertical with respect to the end face of described the second end, and described dividing plate is along the radially setting of described through hole.
Preferably, described dividing plate is vertical with respect to the end face of described the second end, and, described dividing plate has intersection point at projection line and the described taper guide way of the end face of described the second end in the projection of the end face of described the second end, and described dividing plate forms acute angle with the radial slit of the described through hole of the described intersection point of process.
Preferably, the angle of described acute angle is 20 degree.
Spray apparatus in steel pipe water quenching of the present utility model, arranges taper guide way at the through hole that is positioned at the second end, and this taper guide way makes water be divergent shape by the second end to spray, be supplied to steel pipe, improve the shrend homogeneity of steel tube end part.Especially dividing plate adopts the set-up mode with respect to through hole radial skew, and water can, from the ejection of the second end spiral ring, guarantee that steel tube end part supplies water, and improves steel pipe water quenching homogeneity.

Embodiment
Below in conjunction with accompanying drawing, structure of the present utility model and principle of work etc. are further described.
As in Figure 3-5, spray apparatus in steel pipe water quenching of the present utility model, comprises body 10, offers through hole 6 in body 10.Body 10 comprises that first end 1, the second end 3 and connection first end 1 and the second end 3 are to form the sidewall 2 of through hole 6, be that sidewall 2 is between first end 1 and the second end 3, play connection first end 1 and the second end 3 to form through hole 6, and then form the effect of body 10.As shown in Figure 5, sidewall 2 surrounds truncated cone-shaped, and its two ends extend to respectively first end 1 and the second end 3.First end 1 is base, for being connected with water-supply line, is provided with four waist shaped holes 101 on first end 1, can erection bolt to form and be threaded with water-supply line; The second end 3 is for being adjacent to steel pipe, to spray water in steel pipe.The through hole 6 that is positioned at first end 1 is water-in, and the through hole 6 that is positioned at the second end 3 is water outlet, and the aperture of water-in is greater than the aperture of water outlet.In steel pipe water quenching, spray apparatus also comprises the taper guide way 4 that is arranged on the through hole 6 that is positioned at the second end 3, taper guide way 4 is extended to first end 1 by the second end 3, its size is dwindled gradually, between taper guide way 4 and through hole 6 inwalls, be arranged at intervals with in a plurality of dividing plate 5(the utility model, dividing plate is thinner, therefore its projection adopts single line to represent, as shown in Figure 3,4), the quantity of the dividing plate 5 shown in figure is eight.This taper guide way 4 mainly plays the effect of divergent flow, makes water be divergent shape ejection in steel pipe.
As a kind of preferred version of the present utility model, the tapering of truncated cone-shaped sidewall 2 is identical with the tapering of taper guide way 4.
Even for making by the current of spray apparatus ejection in steel pipe water quenching, a plurality of dividing plates 5 are uniformly distributed along the circumferential direction of through hole 6.
The decoration form of dividing plate 5 be take and guaranteed that flow velocity etc. is main purpose, it specifically can be adopted in such a way, be that dividing plate 5 is vertical with respect to the end face of the second end 3, and dividing plate 5 is along the radially setting of through hole 6, as shown in Figure 3, dividing plate 5 is provided with eight along through hole 6 circumferential directions, and every dividing plate 5 is all positioned on the radial slit of through hole 6.
As a kind of optimal way, dividing plate 5 is vertical with respect to the end face of the second end 3, and, dividing plate 5 has an intersection point with taper guide way 4 in the projection (circle shown in figure) of the end face of the second end 3 at the projection line (straight line shown in figure) of the end face of the second end 3, and dividing plate 5 forms acute angle with the radial slit of the through hole 6 of this intersection point of process.As shown in Figure 4, wherein two dotted lines represent respectively the imaginary extended line of dividing plate 5 projections and through hole 6 radial slits of the aforementioned intersection point of process, and these two dotted lines form angle a, and this angle a is above-mentioned acute angle.This structure, makes water spray in the shape of a spiral from the second end 3.Especially this acute angle is 20 while spending, and it can guarantee water flow velocity and flow.
To sum up, spray apparatus in steel pipe water quenching of the present utility model, taper guide way 4 can play the effect of divergent flow, makes steel tube end part can be sprayed onto water, guarantees the homogeneity of steel pipe water quenching.
