Abstract
The utility model relates to an emulsified solution purging device of cold-rolled steel strip, which belongs to the technical field of the auxiliary device of the cold-rolled continuous mill. The utility model aims at providing a purging device which can thoroughly remove the remained emulsified solution on the surface of the rolled steel strip, which consists of a spraying beam and a spraying nozzle, wherein the spraying beam is formed by joining two straight round steel pipes which are intersected with each other in a right-angled way, the plane which is formed by the two intersected round steel pipes is parallel to the plane of the steel strip, the top end direction of an angle which is formed by the two intersected round steel pipes faces towards the rolling advancing direction, a plurality of lateral hole-grooves is arranged below the side of each round steel pipe, the hole-groove faces towards the entering direction of the steel strip, the upper and the lower edge of the hole-groove are respectively provided with a steel nozzle plate, and a spout is arranged between the two nozzle plates. By adopting the emulsified solution purging device, the surface of the steel strip is basically free from the remained emulsified solution, so the corrosion of the strip coil is controlled, the consumption of degreasant at the next procedure is obviously reduced, the disqualification caused by the rust of the substrate is greatly reduced, and the normal production is ensured.
Description
Technical field
The utility model relates to a kind of emulsion blow device that is used for cold-rolled process, belongs to cold rolling middle tandem mill auxiliary equipment technical field.
Background technology
In cold-rolled process, generally after the frame of cold continuous rolling end, all be furnished with the emulsion blow device, in order to the residue of cleaning belt steel surface, reduce corrosion phenomena and take place, entering the degreasing pressure of next procedure thereby alleviate the band steel.The emulsion blow device chief component that present last frame is used be about admission line, spray beam and nozzle up and down.Up and down admission line and up and down spray beam all be the seamless steel pipe of a Q235-A, on spray beam, 15 nozzles are installed with certain interval, each nozzle is made up of nozzle boss and shower nozzle, the material of nozzle boss is Q235-A, and the material of shower nozzle is a brass.During work, compressed air blows to belt steel surface from the nozzle ejection, and the compressed air of nozzle ejection can not cover whole plate face width degree, that is to say there is certain clearance in the middle of the nozzle that place cleaning cleaner of nozzle arranged, and the phenomenon that has just occurred carrying emulsion in the place of nozzle gap, cause gap location at nozzle, the emulsion residue of strip appears in the plate face, and through the interlayer extruding, emulsion is along the trickling of the side of band steel when serious.In the process that postorder is produced, occur cleaning difficulty, speed of production is restricted, and occurs abnormal phenomenons such as plating leakage when serious, greatly reduces the lumber recovery of product.In addition, because nozzle is smaller, often cause the spray nozzle clogging phenomenon in the use, cleaning is also very inconvenient.In order to overcome the above problems, a kind of new emulsion blow device of necessary design changes this situation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of not emulsion blow device of susceptible to plugging cold-strip steel of can removing in residues such as rolling back belt steel surface emulsion and the use.
The technical scheme that solves the problems of the technologies described above is:
A kind of emulsion blow device of cold-strip steel, it is made up of spray beam and nozzle, spray beam is connected to form by two angled crossing straight round steel pipe, plane that two round steel pipe that intersect form and band steel plane parallel, two top orientation that intersect the angle of round steel pipe formation are pointed to rolling direction of advancing, and the side-lower of every round steel pipe has a plurality of horizontal hole slots, the direction that hole slot enters facing to the band steel, lower limb respectively has a steel nozzle plate on the hole slot, is spout between two nozzle plates.
The emulsion blow device of above-mentioned cold-strip steel, it is 90～180 ° that two round steel pipe intersect the angle that forms, hole slot above every round steel pipe is 2～5, spacing between the adjacent hole slot is 10～30mm, hole slot length is 100～200mm, the equal in length of nozzle plate length and hole slot, width 30～60mm, thickness is not more than 5mm, and the width of spout is not more than 5mm.
After adopting this emulsion blow device, belt steel surface does not have residual emulsion substantially, the corrosion problem of coil of strip also is under control, resting period can extend to 360 hours by former 72 hours, and the degreasing agent consumption of next procedure obviously reduces, because the defective work that the substrate corrosion causes significantly reduces, guaranteed normally carrying out of production, simultaneously, clogging did not appear in the blow device after the improvement, and the cost of nozzle also reduces greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a structure schematic top plan view of the present utility model;
Fig. 3 is a nozzle section schematic diagram of the present utility model.
Mark is as follows among the figure: spray beam 1, nozzle 2, hole slot 3, nozzle plate 4, spout 5, air inlet pipe 6, band steel 7
The specific embodiment
Show among the figure, the utility model is made up of spray beam 1 and nozzle 2, spray beam 1 is welded together with certain angle by two seamless steel pipes, and the angle between two steel pipes is between 90～180 °, and the top of the angle that two steel pipes form is towards rolling direction of advancing.Open a plurality of hole slots 3 on every round steel pipe of spray beam 1, hole slot 3 is positioned at the side-lower of steel pipe, facing to the direction of being with steel 7 to enter.Welding certain thickness steel plate at the edge up and down of hole slot 3 is that slit that is not more than 5mm of nozzle plate 4, two block plates formation is a spout 5, and compressed air sprays from slit.Above-mentioned hole slot 3, nozzle plate 4, spout 5 mutual group become nozzle 2 of the present utility model.
Above hole slot 3 on the described every round steel pipe be 2～5, spacing between each is 10～30mm, hole slot 3 length are 100～200mm, opening degree is 30～80mm,, nozzle plate 4 length of welding and the equal in length of hole slot 3, the material of the steel plate of nozzle plate 4 also is Q235-A, width is got 30～60mm, and steel plate thickness is not more than 5mm.
Compressed air enters spray beam 1 by air inlet pipe 6, after storing, spray beam 1 blows on the band steel 7 by nozzle 2, with band steel 7 planes the angle of inclination is arranged owing to form two round steel pipe of jet beam 1, compressed air will be blown off to limit portion by the centre gradually with the residues such as emulsion on steel 7 surfaces under the effect of air-flow.The nozzle 2 purging areas that formed by hole slot 3 and nozzle plate 4 are big, and can not stop up, and cost also reduces greatly.
This device is made simple, and cost is low, easy operating, and result of use is good.
