Description

Rolling oil removal device on strip surface {APPARATUS FOR REMOVING USED OIL TO ROLL THE STRIP}

The present invention relates to a rolled oil removing device of the strip surface, and more particularly to a rolled oil removing device of the strip surface that can effectively suck and remove the rolled oil on the strip surface by using a rotating scraper and magnets.

In general, as shown in Figure 1, during the cold rolling of the strip is carried out a rolling operation while spraying the rolling oil 4 on the surface of the strip 7 that proceeds to the rolling roll (2), conventionally a rolling oil injector The rolling oil 4 injected from (3) passes through the rolling roll 2 like the strip 1 as the strip 1 proceeds, and the rolling oil 4 on the surface of the rolled strip 1 is air. Although it is to be removed by the air injected from the injector (6), when the rolling oil (4) is removed by air, the residual rolling oil (5) is left on the strip surface to reduce the product quality such as poor water quality In addition, a large amount of the rolling oil mist 7 is generated by the injection by air, which causes serious problems such as serious contamination of the surrounding equipment and excessive noise.

In order to solve the above problems, the present invention is installed on the rear end of the rolling roll with a scraper, a magnet and an equilibrium brush to remove the rolling oil to effectively remove and suck the rolling oil on the strip surface to remain on the strip surface It is an object of the present invention to provide a cold rolled oil removing device of a strip surface capable of preventing cold rolled products having excellent surface quality and minimizing contamination of surrounding equipment by rolling oil mist by minimizing rolling oil.

Rolling oil removal apparatus of the strip surface according to the present invention is installed on the upper and lower ends with respect to the strip (1) at the rear end of the rolling roll (2), so that the first rotary shaft 14 is rotated by the drive of the drive motor (11). In this case, the first gear 19 inserted into the first rotation shaft 14 is rotated, and the second gear 20, the third gear 21, and the fourth gear 22, which are engaged with each other, are rotated to rotate each gear and the inner side. The first rotating plate 24 and the second rotating plate 25 are rotated by the action of the gear 23, and the rolled oil recovery unit installed in the circumferential direction is rotated. When the scraper 62 of the recovery device portion is in close contact with the surface of the strip 1, the rolling oil 4 on the surface of the strip 1 flows into the recovery body 61 through the scraper 02 and continues. The surface of the strip 1 of the portion where the rolling oil 4 was removed by the scraper 62 0 while being rotated was rotated so that the balance brush 70 composed of a soft surface was formed by the buffering action of the third spring 71. ) And wipe off the remaining rolling oil (4) neatly.

The rolling oil 4 introduced into the recovery body 61 is lowered while the recovery device unit pulls the S pole of the first magnet 28 and the N pole of the fifth magnet 69 when the recovery device reaches the position of the first magnet 28. In the direction of movement, the rolling oil 4 introduced into the recovery body falls into the oil receiver 27 and is repeatedly discharged to the outside through the recovery pipe 34 to remove the rolling oil 4 on the surface of the strip 1. Done.

The above operation describes the operation of the upper device, and when explaining the operation of the lower device, when the scraper 62 flows the rolling oil 4 on the lower surface of the strip 1 into the recovery body 61, the first magnet The fifth magnet 69 is pulled by the 28, and the rolling oil 4 introduced into the recovery body 61 falls into the oil receiver 27 and is discharged through the recovery tube.

At the same time as the inlet and outlet of the rolling oil 4, the high pressure air is discharged from the injection nozzle 47 of the air pipe 43 installed at the upper and lower suction units, and the rolling oil 4 is buried in the balance brush 70. At the same time, the suction fan 48 installed at one side of the circular cover 42 is rotated to discharge the rolling oil 4 injected by air, and the rolling oil 4 is driven by the suction motor 52 as a whole. The fine particles are discharged.

6 is a cross-sectional view showing the action form of the poles of the magnets for each position shown in FIG. 6 while the first and second rotating plates 24 and 25 are rotated to act by the poles of the magnets at each position.

In more detail, it is as follows.

'C' part and 'D' part is a magnet configuration of the upper device, as shown in the 'C' part when the rotating body rotates and the recovery body 61 of the rolling oil recovery device part arrives at the position of the first magnet 28 , Pulling the third magnet (07) and the fourth magnet (09), the recovery body 61 is pulled down, the hole portion of the third magnet (67) is opened while the introduced rolling oil (4) falls to the bottom Then, the falling rolling oil 4 flows into the oil receiver 27 through the hole portion of the first magnet 28. In addition, when the second magnet 30 reaches the position of the 'D' portion, the third magnet 67 and the fifth magnet 69 are pushed downward as well, and the recovery body 61 portion is pushed as a whole, and the scraper 62 is The rolling oil 4 is introduced into the recovery body 61 while being in close contact with the strip 1.

'E' and 'F' is a diagram showing the magnet configuration of the lower device as the rotating plate rotates when the recovery body 61 reaches the position of the first magnet 28 of the 'E' portion of the third magnet (07) ) Is pushed upward, the recovery body 61 is raised, the scraper 52 is in close contact with the strip (1) to flow the rolling oil 4 of the lower strip into the recovery body 61 and at the same time the fifth magnet (69) is opened while the hole is opened and the introduced rolling oil (4) flows into the oil receiver (27) through the water of the first magnet 28, the recovery body 61 is located in the 'F' portion of the third magnet ( 67 is pulled upward, and the fifth magnet 09 is pushed downward so that the hole is blocked.

As such, the operation is performed continuously and repeatedly as the rotating plate rotates.

As described above, the present invention is to remove the rolling oil sprayed on the surface of the strip during the cold rolling through the scraper, to completely remove the fine rolling particles on the surface of the strip by using a balance brush to prevent the occurrence of defects due to the residual rolling oil It is possible to produce a cold-rolled product having excellent surface quality, as well as to recover the mist generated in the rolling oil (4) has the effect of preventing the pollution of the surrounding equipment and improve the working environment.
