The utility model provides a pair of hot rolling slab band asymmetric cooling device can eliminate the slab band upper and lower surface difference in temperature, alleviates the finish rolling belted steel nose, improves belted steel vertical section metallic structure's homogeneity.
Description
Technical field
The utility model relates to hot rolled strip cooling technology field, particularly a kind of hot rolled strip cooling device.
Background technology
At present; Known hot rolled strip cooling device all is to be sprayed water simultaneously by upper and lower surface that each fresh water (FW) all is the symmetry water spray before cooling, especially the finish rolling zone, but because strip upper surface water characteristics; Therefore the symmetry water spray is asymmetric to the cooling effect on upper and lower surface; Operating mode such as upper and lower surface radiating condition of strip is widely different in addition, causes strip upper surface temperature to be lower than underlaying surface temperature, following problem can occur:
(1) the temperature difference causes upper and lower surface metal ductility different, and after finish rolling F1 frame was rolling, band steel nose was serious; Clash into follow-up chassis equipment, cause equipment damage, shortened equipment life; Aggravated harmful gap of equipment, even caused that compressed steel stops the accident of rolling.
(2) owing to the vertical cross section temperature distributing disproportionation, the metal structure variation also is inhomogeneous in the finish rolling operation of rolling, influences properties of product.
Above problem is particularly outstanding at products such as the high-strength steel of rolling thick specification, pipe line steels, has influenced production stability greatly.
Summary of the invention
The purpose of the utility model provides a kind of hot rolled strip cooling device that can eliminate the upper and lower surface temperature difference of band steel, alleviate finish rolling zone band steel nose phenomenon.
For solving the problems of the technologies described above; The utility model provides a kind of hot rolled strip cooling device; Comprise supply channel and the water spray collector that is provided with nozzle; Said water spray collector is installed in the below of hot rolling line finishing stand entrance area, hot rolled strip, only to the cooling of spraying water of the lower surface of strip.
Further, the axis direction of all nozzles on the said water spray collector becomes 15 degree angles with vertical direction.
Further, the water spray covering of the fan of described all nozzles generations becomes 15 degree with the axis direction of said water spray collector.
Further, said supply channel is installed magnetic valve, flow control valve and flowmeter successively, is connected to said water spray collector then.
The hot rolled strip cooling device that the utility model provides; Its water spray collector is installed in the below of hot rolling line finish rolling porch, hot rolled strip; Only, accurately control spray flow, and the axis direction of the nozzle on the water spray collector and the axis direction of vertical direction, nozzle the water spray covering of the fan that produces and the collector of spraying water all become 15 angles spent through flow control valve and flowmeter to the cooling of spraying water of the lower surface of strip; Both can avoid the uniformity of drowning influence water spray covering of the fan; Also can avoid interfering each other between the adjacent water spray covering of the fan, make the hot rolled strip lower surface receive more uniform flow's cooling, can eliminate the upper and lower surface temperature difference of strip; Alleviate the fine-rolling strip steel nose, improve the uniformity of band steel vertical cross section metal structure.

The vertical cross section cross-sectional schematic of the water spray collector that Fig. 2 provides for the utility model embodiment.
The side cross-sectional schematic of the water spray collector that Fig. 3 provides for the utility model embodiment.
The water spray collector that Fig. 4 provides for the utility model embodiment overlook cross-sectional schematic.
The specific embodiment
Referring to Fig. 1 and Fig. 2, the asymmetric cooling device of a kind of hot rolled strip that the utility model embodiment provides comprises supply channel 2 and the water spray collector 1 that is provided with nozzle 3, and water spray collector 1 is installed in the below of hot rolled strip 10; Supply channel 2 is equipped with magnetic valve 4, flow control valve 5 and flowmeter 6 successively, is connected to water spray collector 1 then; As shown in Figure 3, the angle 9 that the axis direction of nozzle 3 is become with vertical direction is 15 degree; As shown in Figure 4, the water spray covering of the fan 7 that nozzle 3 is produced is 15 degree with the angle 8 of the axis direction generation of water spray collector 1.
When using this cooling device, quote the band steel cooling water in finish rolling zone, be transported to the water spray collector 1 that is positioned at hot rolled strip 10 belows through supply channel 2; Be sprayed onto cooling water through the nozzle 3 on the water spray collector 1 lower surface of hot rolled strip 10; Hot rolled strip 10 is carried out asymmetric cooling, because the angle 8 that the axis direction of the water spray covering of the fan 7 that the angle 9 that the axis direction of nozzle 3 is become with vertical direction is 15 degree, nozzle 3 to be produced and water spray collector 1 produces also is 15 degree, the spray water uniformity of covering of the fan 7 of the influence of both can having avoided falling into water; Also can avoid interfering each other between the adjacent water spray covering of the fan 7; Make hot rolled strip 10 lower surfaces receive more uniform flow's cooling, and utilize the magnetic valve 4 gauge tap sequential on the supply channel 2, utilize flow control valve 5 control spray flows; Utilize flowmeter 6 as flow monitoring; Can control spray flow accurately, can eliminate the upper and lower surface temperature difference of strip, improve the uniformity of band steel vertical cross section metal structure.
When finish rolling F1 frame outlet band steel nose is serious; Use this device that hot rolled strip 10 lower surfaces are sprayed water; Before finish rolling F1 frame is stung steel,, can accurately adjust spray flow through flow control valve 5 and flowmeter 6 according to on-the-spot nose amplitude; Alleviate the nose amplitude of band steel, portion is little trend of sticking up up to the band steel toe.
It should be noted last that; The above specific embodiment is only unrestricted in order to the technical scheme of explanation the utility model; Although with reference to instance the utility model is specified, those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of the utility model; And not breaking away from the spirit and the scope of the utility model technical scheme, it all should be encompassed in the middle of the claim scope of the utility model.
