Abstract
The utility model provides a steel plate surface cooling water purging device, which comprises a conveying roller way, a collecting pipe and a compressed air pipeline; the middle bent collecting pipe spans across the steel plate conveying roller way, one end of the collecting pipe is closed, the other end of the collecting pipe is connected with a compressed air pipeline, and spray holes are uniformly distributed on the lower surface of the pipe body side of the collecting pipe. The middle bending peak of the header is positioned on the central line of the steel plate conveying roller way, and the direction of the middle bending peak is opposite to the running direction of the steel plate. Because the middle bent collecting pipe is adopted, the blown compressed air forms a triangular blowing surface with the middle extending forwards and backwards successively, and the residual cooling water on the surface of the steel plate can be blown away from the surface of the steel plate from the central line of the steel plate outwards, so that the blowing effect is improved, and the plate shape quality of the steel plate is ensured.
Description
Technical field
The utility model belongs to the steel rolling equipment field, relates in particular to a kind of be used to the blow device of removing control cooling metal sheets remained on surface cooling water.
Background technology
At present, domestic hot rolling mill is when the production control cooling metal sheets, generally adopt the blow device of straight tube shape collector, behind the cold steel plate output of control control cooling system, purge by the residual cooling water of the straight tube shape collector parallel with outlet roller to surface of steel plate, but because the compressed air that straight tube shape collector blows out formation is a concordant purging face, the surface of steel plate after therefore purging still has residual cooling water, has directly influenced the strip shape quality of steel plate.
Summary of the invention
The utility model is intended to eliminate above-mentioned defective, and a kind of residual cooling water that can thoroughly remove surface of steel plate is provided, thereby improves the blow device of the strip shape quality of steel plate.
For this reason, the solution taked of the utility model is:
A kind of surface of steel plate cooling water blow device comprises the steel plate rollgang, it is characterized in that, is made up of collector and compressed air piping; The collector of middle bending is across on the steel plate rollgang, the sealing of collector one end, and the other end is connected with compressed air piping, is evenly equipped with spray orifice on below the collector pipe shaft side.
The angle of bending is 120 °～150 ° in the middle of the described collector.
The bending summit is positioned on the steel plate rollgang center line in the middle of the described collector, and the bending summit is towards opposite with the steel plate traffic direction.
The beneficial effects of the utility model are:
Because the collector of bending in the middle of the utility model adopts, therefore make the compressed air that blows out formed a centre forward, the triangle that extends back one by one purges face, can be with the residual cooling water of surface of steel plate from the steel plate center line surface of steel plate that outwards blows off fully, purge effect thereby improve, guaranteed the strip shape quality of steel plate.
Description of drawings
Fig. 1 is surface of steel plate cooling water blow device installment state stereogram.
Among the figure: control cooling device 1, collector 2, roller-way 3, spray orifice 4.
The specific embodiment
As seen from Figure 1, the utility model surface of steel plate cooling water blow device mainly is made up of collector 2, roller-way 3 and compressed air piping.Collector 2 adopts round steel pipe to make, and the centre is bent into 130 ° angle, evenly offers 20 spray orifices 4 on below the side of collector 2 pipe shafts.The sealing of collector 2 one ends, the other end is connected with compressed air piping, and collector 2 is across on the rollgang 3 of control cooling device 1 outlet steel plate.During installation, should guarantee that bending summits in the middle of the collector 2 align the center line of roller-way 3, and the bending summit is namely opposite with the steel plate traffic direction towards the outlet of control cooling device 1, is beneficial to purge air-flow with the residual cooling water surface of steel plate that blows off.
