Specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.
As shown in figs. 1-7, the strip width of the present embodiment is to the controlled chiller of cooling uniformity, including cooling strip
11st, along board rolling direction is continuous or spaced multiple cooling zone, usual cooling zone is three, four, and the present embodiment is three
Individual, respectively cooling I area, cooling II area and cooling III area, it is provided with water seal barrier means 1 between cooling zone, at last
The exit of individual cooling zone cools down and is provided with aerosol separating device 2 at III area, the cooling cleannes of purification plate belt surface, often
Individual described cooling zone includes intensive upper spray equipment 3, lower spray equipment 4, hand-operated valve 7, water balance pipe 8 and intensive upper spray is filled
Put 3 and lower spray equipment 4 carry out opening or closing the Pneumatic opening ＆ closing adjusting means 5 of spray operation, hand-operated valve 7, intensive upper spray
Device 3, lower spray equipment 4 and Pneumatic opening ＆ closing adjusting means 5 are connected with water balance pipe 8 by pipeline 9, described intensive upper spray dress
Put be provided with 3 can its injection flow rate of dynamic regulation spray tunable arrangement 6, cold theoretical by controlling：The water spray of spray thrower
Amount and the water-flow equation along width and length direction are the key factors affecting strip spraying cooling, thus to plate width side
To and longitudinal direction on cooling uniformity be cooling control a very important index, because middle part injection flow rate leads to
To both sides diffusion, the cooling water inflow of edge also should be made in theory different with the cooling water inflow at middle part, simultaneously with Strip
Its water spraying mode of the heterogeneity of matter more should be different, if only rely on the integrally-regulated of valve may not be used in actual production
It is well positioned to meet use requirement.The present embodiment is exactly spray thrower to be adopted with preset value, revises adjustable convexity pattern, symbol
The width with spraying cooling for the plywood to cooling law,
As shown in figure 5, the spray tunable arrangement 6 of the present embodiment includes inserting column jecket 61 He of intensive upper spray equipment inner chamber
By adjusting nut 62 is fixing and its insertion column jecket 61 of scalable in length adjustable nozzle 63, described column jecket 61 and adjustable spray
It is provided with flow adjusting structure, it specifically includes the conical surface 64 being arranged on column jecket end inner chamber and is arranged on adjustable spray between 63
The seal plug 65 of end surface, described seal plug 65 is coordinated and is finely tuned between the two by adjusting nut 62 with the conical surface 64
Distance, and then adjust seal plug 65 and fit with the conical surface 64 level, thus the tune to adjustable nozzle 63 water outlet caliber size for the realization
The whole adjustment with water yield is it is generally the case that described adjustable nozzle caliber size is in normal distribution on plate width direction, such as
Shown in Fig. 6, meanwhile, by initial designs, adjustable nozzle is also in normal distribution is arranged on plate width direction, finally makes cold
But the water yield of water is parabolically distributed on plate width direction, as shown in Figure 7 so that strip cools down need in the width direction
The water yield tends to actual demand, reaches the uniform and controlled purpose of cooling.
As the improvement of the present embodiment, for realizing carrying out mandatory cooling to different strips, will intensive upper spray equipment and
The ratio of the flow of lower spray equipment is set to 1：1.5～1：2.5, can reach more preferably effect.
As the improvement of the present embodiment, as shown in figure 5, being additionally provided with unhurried current bascule 10 in intensive upper spray equipment,
By the pressure of the bascule 10 adjusting water exit amount that flows slowly, further shower water is adjusted together with spray tunable arrangement
Section, makes the power that amount of cooling water is a matching, this curve is identical with the thermal characteristic treating cold belt steel, thus improving cold
But quality.
Enforcement this utility model embodiment strip width is set up on the ultrafast chiller of cut deal controlled to cooling uniformity
Chiller can effectively increase the cooling of spraying cooling collector comprehensively controlled ability and target anastomosis adaptability it is achieved that
Consistent corresponding control ability is reached by spray equipment requirement objective, reaches the uniformity cooling control meeting plate ＆ strip production
The purpose of system；
Compared with the existing ultrafast cold water spray device not installing this adjusting means, the strip width of the present embodiment is to cooling all
The controlled chiller of even property has the advantage that：
1) improve the pressure buffer balanced capacity within ultrafast cold water spray collector, change existing conventional ultrafast cold water spray
Collection overpressure is irregular and the big deficiency that fluctuates, and provides power source for uniform water outlet；
2) improve the control ability of required cooling water inflow when ultrafast cold water spray device changes to strip wide cut, can be according to cold
But the heat exchange amount of target strip is sprayed water according to the fluidised form on width, uniformly cold on strip width direction to meet
But demand.
3) intensive spray thrower is individually controllable to cooled region flexibly, and regulating measure is big.To sum up, the strip width of the present embodiment
The control ability of the ultrafast cooling of hot rolled steel plate can be effectively improved to the controlled chiller of cooling uniformity, and enhancing is right
The control ability of strip wide cut cooling uniformity
Finally illustrate, preferred embodiment above only in order to the technical solution of the utility model to be described and unrestricted, to the greatest extent
Gutron is crossed above preferred embodiment and this utility model is described in detail, but those skilled in the art should manage
Solution, can make various changes, in the form and details without departing from this utility model claims institute to it
The scope limiting.
