Abstract
The invention relates to aluminum rolling mill machining equipment, in particular to a roll gap sweeping nozzle device which is arranged behind aluminum rolling mill work rollers and located on a splash board. The roll gap sweeping nozzle device comprises a splash board, an air inlet pipe is arranged on the splash board, a nozzle with a nozzle exit facing a roll gap is arranged on the air inlet pipe, the nozzle can form a sector-shaped spray surface and is of a flat structure, and the sector-shaped spray surface can cover the overall roll gap in width when reaching the roll gap. According to the roll gap sweeping nozzle device on the splash board of the aluminum rolling mill , a plurality of small nozzles in the prior art are replaced by the big nozzle, so that the sweeping range is guaranteed, the sweeping overlap phenomenon is avoided, and the problem of oil on the surface of a rolled aluminum strip is solved.
Description
Technical field
The present invention relates to a kind of aluminium milling train process equipment, specifically a kind of be arranged on aluminium operation roll of mill rear, be arranged on splash-back, roll gap purges spray Zi, one of the lunar mansions device.
Background technology
The rear of aluminium operation roll of mill is provided with splash-back, on described splash-back, nozzle has been installed.Compressed air, by the purging of nozzle, is taken away the ROLLING OIL on aluminum strip surface.
Aluminium milling train comprises top working roll and the bottom working roll of two horizontal positioned, and aluminum strip is passed through between two working rolls.The top of described top working roll is also provided with the pressure roller of a horizontal positioned.Two row's nozzles have been installed on the splash-back at working roll rear, and row's jet hole is facing to the roll gap forming between top working roll and bottom working roll, and another row's jet hole is facing to the roll gap forming between top working roll and pressure roller.
Existing structure is for as shown in Figure 1: in an air inlet pipe, arranged several nozzles, when work, due to adjacent two nozzles, there is an overlay region in the gas of ejection, forms and interfere, and purges unclean, cause the strip surface band oil after rolling, affect product quality.
Summary of the invention
Technical problem to be solved by this invention is, a kind of mutual interference can avoid nozzle to purge time is provided, guarantees the aluminium milling train splash-back roll gap purge nozzle device of the quality that nozzle purges.
Technical scheme of the present invention is: a kind of aluminium milling train splash-back roll gap purge nozzle device, comprise splash-back, and on described splash-back, air inlet pipe is installed, the nozzle that a jet hole is aimed at roll gap is installed in described air inlet pipe; Described nozzle is for can form nozzle fan-shaped spray face, flat structure, and width when described fan-shaped spray face arrives roll gap covers whole roll gap.
The angle of the fan-shaped spray face that described nozzle can form is 120 degree.
The invention has the advantages that: several small nozzles of an original row are changed into a giant, can guarantee purging scope, can not produce purging overlapping phenomenon again, solved a difficult problem for aluminum strip surface band oil after rolling.
Accompanying drawing explanation
Fig. 1 is the top view of existing aluminium milling train splash-back roll gap purge nozzle device;
Fig. 2 is the top view of aluminium milling train splash-back roll gap purge nozzle device of the present invention;
Fig. 3 is the installation site schematic diagram of aluminium milling train splash-back roll gap purge nozzle device of the present invention on aluminium milling train.
The specific embodiment
As shown in the figure, a kind of aluminium milling train splash-back roll gap purge nozzle device, comprises splash-back 1, on described splash-back 1, air inlet pipe 2 is installed, and the nozzle 3 that a jet hole is aimed at roll gap is installed in described air inlet pipe 2; Described nozzle 3 is for can form nozzle fan-shaped spray face, flat structure, and width when described fan-shaped spray face arrives roll gap covers whole roll gap.
The purging scope of described nozzle 3 can cover whole roll gap, and described nozzle 3 is chosen the structure that exactly likes " flat duckbilled ", at air, sprays in purge, can guarantee purging scope, can not produce purging overlapping phenomenon again.
Claims (2)
1. an aluminium milling train splash-back roll gap purge nozzle device, comprises splash-back (1), and air inlet pipe (2) is installed on described splash-back (1), it is characterized in that: the nozzle (3) that a jet hole is aimed at roll gap is installed in described air inlet pipe (2); Described nozzle (3) is for can form nozzle fan-shaped spray face, flat structure, and width when described fan-shaped spray face arrives roll gap covers whole roll gap.
2. aluminium milling train splash-back roll gap purge nozzle device according to claim 1, is characterized in that: the angle of the fan-shaped spray face that described nozzle (3) can form is 120 degree.
