Description

Nozzle head apparatus for degreasing strip with spray angle control and blocking sense function}

The present invention relates to a degreasing process for removing the rolling oil on the surface of the strip during cold rolling of the cold rolled steel sheet, and more specifically, to the degreasing sprayed on the upper and lower surfaces of the strip so as to degrease the rolling oil on the strip surface. SPRAY ANGLE of the solution (DEGREASING SOLUT ION) can be adjusted and sprayed so that the degreasing solution does not overlap, and at the same time, when the nozzle is clogged, it can be detected and cleaned quickly to improve strip degreasing efficiency. Of course, the present invention relates to a stripping nozzle head device having a spray angle adjustment and clogging detection function to extend the life of the nozzle head.

In general, stainless steel strips are manufactured in a stainless steel cold rolling mill through a continuous annealing and rolling process. The surface of the strip subjected to the rolling process is rolled with oil, and a degreasing process for removing them is essential. The reason why the process is necessary is that if the rolling oil adheres to the surface of the strip during the plating process, the shape correction and the surface treatment process, which are post-processes, it cannot be precisely performed.

1 illustrates a conventional strip degreasing operation.

That is, as shown in Figure 1, the degreasing solution supply pipe 110 is installed to extend to the outside of the degreasing tank 100 on the upper and lower surfaces of the strip (S) transported through the inlet, outlet of the degreasing tank 100 and Degreasing solution (D) is injected through the nozzle nozzle 120 of the upper and lower nozzles connected to remove the rolling oil on the strip surface.

However, in the above conventional strip degreasing operation, the spray nozzle 130 installed in the nozzle head 120 is sprayed in a state in which the spray angle of the degreasing solution D cannot be adjusted. As described above, when the degreasing solution (D) is sprayed, there is a spray area (A) overlapping each other, which causes a difference in the injection pressure due to the overlap of the sprayed degreasing solution, which in turn causes severe vortex to degrease the strip surface. This results in a defect, which results in the formation of uneven strips of unremoved oil on the strip surface after the strip grooves or degreasing on the strip surface, which affects the post-processing and degrades the quality of the strip.

In addition, in order to prevent the injection nozzle 130 of the nozzle head 120 from being partially blocked, the worker manually washed the nozzle grooves of the respective injection nozzles 130 through the cover of the degreasing tank 110. First, it is impossible to detect the blockage of the spray nozzle 130 as described above, and the degreasing defect of the strip is frequently generated by the spray nozzle 130 which is partially blocked. In the cleaning operation of the spray nozzle 130 described above, After the operator disassembles the entire nozzle head 120 from the supply pipe 110, there are various problems such as cleaning each nozzle groove.

The present invention has been made in order to improve the various problems as described above, the object of which is to detect the clogging of the nozzle quickly to prevent the stripping of the strip, while disassembling and assembling the injection nozzle as a whole and easy injection nozzle Cleaning of the strip is easy, and in particular, during the stripping operation, the spray angle of the stripping solution can be easily adjusted so that the stripping area does not overlap, and the stripping solution is more uniformly sprayed on the surface of the strip. SUMMARY OF THE INVENTION An object of the present invention is to provide a stripping nozzle head device having a spray angle adjustment and clogging detection function that further improves workability.

That is, a plurality of nozzle heads 20 of the circular pipe are arranged in the upper and lower sides of the strip S to the inside of the degreasing tank 10, and in particular one end of the nozzle head 20 to the outside of the degreasing tank 10. This is for projecting the nozzle angle adjustment and nozzle clogging detection described above.

On the other hand, a plurality of nozzle means 50 are arranged on the outer circumferential surface of the nozzle head 20 at regular intervals, the vertical of the binding rod 54 provided to the outside of the through hole 24 formed in the nozzle head 20 When the above-mentioned pneumatic nozzle hole 40 is formed through the insertion path 52b, and both moving bars 54a of the nozzle plate 54 are inserted and lowered through one sealing plate 56a downward, A certain angle is rotated left and right along the lower moving rail 52a of the binding rod 52, and the nozzle plate 54 in which the nozzle hole 40 is formed is able to rotate left and right.

At this time, the stopper 58 is coupled to the screw groove 52c of the binding rod 52 via the sealing plate 56b to the upper side of the nozzle plate 54, and an outlet (at the center of the stopper 58). 58a is formed, so that the degreasing solution supplied through the nozzle head 20 is sprayed through the head through hole 24, the nozzle hole 40 of the nozzle plate, and the outlet 58a of the stopper 58. In this case, the outlet 58a of the plug 58 is considerably larger in diameter than the nozzle hole 40.

In addition, looking at the connection between the nozzle head 20 and the supply pipe 12 installed to the outside of the degreasing tank 10, the degreasing solution supply pipe 12 has one end 60a of the cylindrical cover 60 as a protective member.
