Foreign material removal device on roll surface {APPARATUS FOR REMOVING ALIEN MATERIALS FROM THE SURFACE OF ROLL}

The present invention relates to a device for removing foreign matter attached to the roll, and more specifically, without damaging the surface of the roll by using a tube member and a removal blade that selectively expands the foreign matter attached to the deflection roll passing through the non-solidified steel sheet. The present invention relates to a debris removal device on a roll surface capable of removing and collecting and removing the debris.

1 is a schematic view showing a hot-dip galvanizing equipment of a general steel mill. As shown, the steel sheet 9 passing through the heating furnace 101 equipment is provided with an air knife device installed in the upper part immersed in the galvanizing tank 102 ( The amount of zinc plating attached to the surface of the steel sheet is controlled by 103, and then primary cooling is performed by the cooling device 104a installed in the upper pass 104.

Subsequently, the steel sheet 9 which is first cooled while passing through the upper pass 104 is shifted in direction by deflection rolls 105a and 105b to be secondaryd by the cooling device 106a of the lower pass 106. After cooling, the process proceeds to the next process via the final deflection roll 107.

At this time, since the steel sheet 9 which is first cooled and then passes through the deflection roll 105a is not completely cooled, zinc powder is generated in the friction surface with the deflection roll 105a, which is a deflection roll 105a. ), And it turns into zinc pieces. Therefore, a defect such as a dent mark is generated on the surface of the steel sheet that passes through the deflection roll 105a, thereby causing a product defect.

On the other hand, in order to remove foreign substances such as zinc chips adhered to the surface of the deflection roll 105a, the deflection roll (the other end of the deflecting roll 110 as shown in FIG. 105a) The zinc pieces 8 attached thereto were fixed by fixing to one side.

However, in the removal of foreign matters such as zinc pieces, the conventional removal device 110 is removed from the deflection rolls 105a and the zinc pieces 8 dropped therefrom are not completely separated and scattered around the deflection rolls 105a. The reattachment to the surface of the steel sheet and the deflection roll 105a has a problem that complete separation and removal of the zinc pieces 8 is difficult.

In addition, since the removal device 110 is a fixed type, there is a problem of damaging the surface of the deflection roll 105a, which is always in contact with the end of the removal blade.

Accordingly, the present invention has been made to solve the above problems, the purpose of which is to remove the foreign matter attached to the roll surface by temporarily contacting the removal blade to confirm that the foreign matter is attached to the deflection roll of the roll surface It is to provide a foreign material removal device of the roll surface to suppress the damage to the maximum, and can be completely separated so that the foreign matter removed and removed is not reattached to the roll surface, the steel sheet.

The operation and effects of the present invention having the configuration as described above will be described.

First, as shown in Fig. 7 (a), as a result of checking the surface of the roll 105a via the steel sheet 9 cooled first after the plating operation with the naked eye or using a camera 49, the amount of foreign matter attached is large. When it is judged that there is a high possibility of deteriorating the quality of the steel sheet, the operator operates the switch 43d in the operation panel 43 installed in the cab to send an electrical signal to the control valve 41 to supply the first air supply pipe 19a. When the air which is a fluid is selectively supplied and expanded through only the first tube 14a through the first and second tubes 14a and 14b, the volume expansion degree is different as shown in FIG. 7 (b). The operating plate 11 assembled to the rotary rod 13a is pivoted so that the removal blade 12 at the tip comes into contact with the surface of the rotating roll 105a.

Generated, and forced suction of external air in front of the suction port (32).

In this state, foreign matters such as zinc powder and zinc flakes attached to the surface of the roll 105a rotated in one direction by the steel sheet conveying operation by the removal blade 12 having the end of the roll 105a contacted with the surface are removed. At the same time as dropped by 12), the foreign matter dropped out is sucked together with the air into the suction pipe 31 through the suction port 32 by the strong suction force of the suction pipe 31 to connect the connection hose 33, the communication pipe 35 It is introduced into the dust collector 51 through.

Subsequently, foreign substances introduced together with the external air are collected in the dust collector 51 together with the water by the cooling water injected from the nozzle 53 and then discharged to the sludge pits 54 when the discharge valve 54 is opened. While drained to the pit 57 and reused or drained, the foreign air filtered out is filtered again by the filter member 58 and then exhausted to the outside.

After confirming with the naked eye or the camera 47 that all the foreign matter adhering to the surface of the roll 105a has been removed by the above-described removal operation, operate the switch 43e of the operation panel 43 in the opposite manner to the above. When the air, which is fluid, is selectively supplied to and expanded through only the second tube 14b through the second air supply pipe 19b through 41, as shown in FIG. The operating plate 11 assembled to the rotating rod 13a by 14b) is pivoted so that the removal blade 12 at the tip is spaced apart from the rotating roll surface to prevent damage to the roll surface, and at the same time, the operation panel 43 When the external power is cut off to the suction pump 34 by using the switch 43c of), the suction force generation in the suction pipe 31 is stopped and the foreign material removal operation is finished.

On the other hand, when the distance between the removal blade 12 and the roll 105a is widened due to the end of the removal blade 12, the distance of each of the first and second adjusters 22a and 22b is reduced. After releasing each of the fixing pins 24 of the first control bundle 24a, 24b and the second control bundle 24c, 24d assembled so as to slide in the slide holes 23a, 23b, the main The first and second adjustment blocks 24a, 24b, 24c and 24d are simultaneously roll 105a such that the first and second moving blocks 25a and 25b connected to the plate 15 are moved to the roll 105a side. When the fixing pin 24 is tightened again, the distance between the blade 12 and the roll 105a of the operation plate 11 installed on the main plate 15 can be easily adjusted to a desired length. It is.

According to the present invention having the configuration as described above, the operation is rotated by the first and second tubes (14a) and (14b) to selectively inflate the fluid by selectively introducing the fluid only in the state that the foreign matter is attached to the roll surface Since foreign matter adhering to the surface of the rotating roll 105a as the removal blade 12 of the plate 11 can be removed, damage to the surface of the roll can be prevented, and the removed foreign matter is sucked in as a suction force of the suction pipe 31. Since the dust collector 51 can be post-processed, a substantial effect can be obtained by preventing the foreign matter removed from reattaching to the steel sheet 9 or the roll 105a, thereby improving the quality of the plated steel sheet.
