The present invention relates to a strip passing through the bright annealing line exit annealing furnace of stainless steel, in particular, the surface of the strip to be adsorbed and removed by adsorbing foreign matter pressed during the transfer of the strip or powder formed during the heat treatment process of the strip It relates to a foreign material suction removal device.

In general, stainless steel is an oxide scale formed on the outer surface of the strip during the heat treatment of the strip formed in the cold rolling process in the annealing furnace of the oxidative atmosphere as a means for recrystallization or softening of the material. This scale of oxidation is removed by a pickling process.

Here, the strip of stainless steel is characterized in that the oxidation scale of the surface is removed during the pickling process, but the surface roughness is increased and thus the gloss is degraded. Therefore, the strip subjected to this pickling process is heat-treated in an annealing furnace under a reducing atmosphere. A so-called bright annealing method has been proposed.

However, since the strip of stainless steel is heat-treated in the process of passing through the bright annealing furnace, oxides such as powder are formed on the outer surface thereof, as well as foreign matters are attached to the bright annealing furnace and proceeded to the post-treatment process. The use of a debris removal device such as FIG. 1 is essential.

That is, as illustrated in FIG. 1, foreign substances pressed on upper and lower surfaces of the strip 110 drawn out in the heat-treated state in the bright annealing furnace 100 are seated on the deflector roll 120 and the blade roll 130 and wound up. In the process of transferring to the machine, it is removed by the debris removal device 140 installed on the transport path of the strip (110).                         

Of course, the foreign material removal device 140, a pair of lifting cylinder 142 mounted on the ceiling surface of the support frame 141, the support frame 141 of the "C" shape installed on the transport path of the strip 110. Is mounted on the rod of the lifting cylinder 142 is composed of a foreign material removal roll 143 in contact with the upper surface of the strip (110).

Therefore, when the lifting cylinder 142 of the foreign matter removing device 140 is in close contact with the foreign material removing roll 143 to the upper surface of the strip 110, foreign matter such as powder is removed in the course of the strip 110. will be.

By the way, the debris removal device 140, the debris removal roll 143 is in close contact with the upper surface of the strip 110, the foreign matter of the lower surface of the strip 110 is not possible, of course, of the lifting cylinder 142 Since the foreign matter removal roll 143 is fixed to the rod, there is a problem that the work load due to separation and washing is increased.

In addition, when winding the strip 110 by using a winding machine in a state in which it is not possible to remove white powder or foreign substances by the debris removing roll 143, not only surface defects of the strip 110 are generated, but also the quality of the product. Of course, there was a problem in that waste factors such as the generation of scraps are lowered.

Accordingly, the present invention has been made to solve the problems described above, the foreign matter on the surface of the strip to improve the removal efficiency by separating and removing the powder or foreign matter attached to the upper and lower surfaces by the suction process It is an object to provide a suction removal device.

Of course, it is preferable to mount the ground plate 80 formed of a copper material through a cable in the transfer path of the strip 110, to prevent foreign matter coming off the strip 100 to be pressed again by the static electricity.

Hereinafter, described in detail with reference to the accompanying drawings illustrating the operation according to the present invention.

First, the strip 110, which has been heat-treated in the bright annealing furnace 100 and drawn out, is refracted at a predetermined angle through the deflector roll 120, and then bled through the passage hole 11 of the housing 10 according to the present invention. It is guided in the state mounted on the roll 130, and it is wound up in coil shape by a post-processing process, ie, a winder.

In this process, when the detection sensor 61 provided on the inner wall of the housing 10, that is, the inlet side of the passage hole 11, detects the hole H formed in the front end of the strip 110, Since the controller 60 outputs an operation signal to the position sensor 62, the motors 21 and 22 and the cylinders 23, 24, 51 and 52 are operated as well as the solenoid valves 41 and 42 are opened.

At this time, in the process of operating the front cylinder 51 of the front foreign material remover 50 received the signal of the controller 60, the front roll coupled to the rod of the front cylinder 51 through the pin (P) ( As the 54 is upwardly contacted with the lower surface of the strip 110 guided into the through hole 11, foreign substances are removed.

At the same time, the upper and lower brushes 25 and 26 are rotated by the motors 21 and 22 receiving the signal of the controller 60, and the upper and lower brushes 25 and 26 are lifted by the cylinders 23 and 24. The foreign matter attached to the upper and lower surfaces of the strip 110 is to be crushed.                     

At the same time, the solenoid valves 41 and 42 of the air compressors 40 and 40 'are opened so that the air in the air tanks (not shown) moves up and down through the air injection ports 43a and 43a' of the air compressor pipes 43 and 43 '. Since it is sprayed toward the brushes (25, 26), the foreign matter that is stuck to the upper and lower brushes (25, 26) will fall off.

Of course, the foreign matters falling off the upper and lower brushes 25 and 26 are sucked in the operation process of the fan 72 constituting the dust collector 70 and filtered through the filter 71 via the suction pipe 32. It is discharged to the treatment process.

Subsequently, the foreign matter remaining on the upper surface of the strip 110 is rearward coupled to the rod of the rear cylinder 52 through the pin P in the process of being drawn out through the passage hole 11 of the housing 10. It is removed by the roll 55.

If the front and rear rolls 54 and 55 of the front and rear foreign material removers 50 and 50 'are to be replaced, as shown in Figs. 4A and 4B, the receiving grooves 58a of the fixing member 58 are obstructed. After removing the pin (P) inserted through the machine (55a) is to replace the rear roll (55).

As described above, according to the apparatus for removing foreign substances on the surface of the strip according to the present invention, since foreign substances in the strip formed during the heat treatment process of the bright annealing furnace are completely removed by the suction removal apparatus, the foreign substances formed on the upper and lower surfaces of the strip are removed. In addition to preventing the degradation of quality caused by defects, foreign substances removed from the strip is sucked through the upper and lower hoods, filtered by the dust collector, and then transferred to the post-treatment process, thereby minimizing environmental pollution.                     

In addition, when the foreign matter removing roll according to the present invention is damaged, since the exchange operation is easily performed, the work load due to the separation and washing of the foreign matter removing roll is reduced as well as the overall incident cost is reduced.
