BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roll cleaning apparatus, and more particularly, to a roll cleaning apparatus capable of producing high quality steel sheet by removing foreign matter from the surface of a work roll of a rolling mill in a rolling mill.

In general, the rolling process of steel mills refers to a process of increasing or thinning slabs, volumes, billets, etc. produced in a continuous casting process by passing them between rotating rolls. This rolling process is divided into a hot rolling process and a cold rolling process. Especially in the production of stainless steel sheet, the cold rolling process is performed.

Figure 1 schematically shows a rolling mill according to the prior art in this cold rolling process. In the rolling mill 10, a braking drum 12 is positioned on the right side and a tension drum 14 on the left side, assuming that the material 11 proceeds in the direction of the arrow in the drawing. Material to which work rolls 15 and 16 exert a constant rolling force on both sides of the top and bottom, and idle rolls 18, 19, 20 and 21 are mounted on the bottom of the material on both sides of the work rolls 15 and 16. Prevent (11) from sagging downwards and smooth the transfer.

This conventional rolling mill 10 works at a desired thickness from the work rolls 15 and 16 at a constant reduction rate when the material 11 is transferred from the braking drum 12 to the tension drum 14.

However, since the above-mentioned material 11 contains a large number of foreign matters before it is completely processed, a roll mark is generated on the surface of the material to be worked between the work rolls 15 and 16 during the work. Will drop significantly.

  In the past, since there was no device for removing foreign matter from the surfaces of the work rolls 15 and 16, the worker had to manually remove the foreign matter attached to the surface of the work roll. In addition, it was impossible to check the surface of the work roll at once, and also had problems such as poor work efficiency and worsened productivity.

The present invention has been invented to solve the above problems, an object of the present invention is to remove the foreign matter from the surface of the work roll during the operation to produce a high-quality steel sheet, and to prevent safety accidents and increase the work efficiency to improve productivity It is to provide a roll cleaning apparatus to increase.

In order to achieve the above object, the present invention, the supply shaft is formed toward the surface of the work roll to a length corresponding to the width of the work roll and forming a wiper made of a cloth material so that the wiper is supplied while rotating in the wound state; It is equipped with a fixed shaft for fixing the end to which the wiper is conveyed, and between the wiper to support the wiper toward the work roll, and forms an adsorption means for adsorbing foreign substances generated from the material with a magnetic and A cleaning unit configured to mount rail means for enabling forward and backward movement to both sides; An actuating unit configured to mount a motor connected to the fixing shaft and the clamp of the cleaning unit, and to form a brake means for compressing a pad by a cylinder to a disk connected to the supply shaft and the clamp; A guider which forms a mounting plate on which the cleaning unit and the operating unit are mounted, and which are mounted on both sides of the mounting plate on both sides to lift up and down the mounting plate, and guiders mounted on both sides of the cylinder to guide the mounting plate up and down. And a support part formed by forming a pedestal for supporting the cylinder and the guider.

Hereinafter, the most preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

2 is a view showing a state in which a roll cleaning apparatus according to an embodiment of the present invention is mounted on a rolling mill, and the same parts as in FIG. 1 will be omitted and the same reference numerals will be given.

As shown in the figure, the roll cleaning apparatus 100 according to the present invention is installed at the bottom of the work roll 16 and serves to remove foreign substances attached to the surface of the work roll while contacting the surface of the work roll.

3 is an overall perspective view of a roll cleaning apparatus according to the present invention, the roll cleaning apparatus 100 of the present invention is composed of a cleaning unit 110, the operation unit 150 and the support 180.

The cleaning part 110 is formed toward the surface of the work roll 16 to a length corresponding to the width of the work roll 16, and forms a wiper 112 made of a cloth material and supplies the wiper 112 to supply the wiper 112. It is equipped with a fixed shaft 116 for tensioning and securing the shaft 114 and the other end, and between the inside of the wiper 112 to support the wiper 112 toward the work roll 16 from the material with magnetic It is formed by forming the adsorption means 120 for adsorbing the generated foreign matter and mounting the rail means 140 to enable forward and backward movement on both sides of the adsorption means 120.

The wiper 112 is supplied from the supply shaft 114 and wound around the fixed shaft 116. The supply shaft 114 can supply the wiper 112 while being rotated in an initial state of use. It is mounted so as to be supported by the bearing 115 to the support 180. Although not shown, the fixed shaft 116 splits the shaft in the longitudinal direction to fix the initial end of the wiper 112 supplied therebetween while rotating and winding the wiper 112 while unwinding from the fixed shaft.

The adsorption means 120 is formed to have a semi-circular cross section as shown in FIG. 4 and to place the felt 122 into the wiper 112 and to place a magnet 124 inside the felt 122. Form. The magnet 124 is supported by the support bracket 126 on both sides, and the support bracket 126 is coupled to the rail means 140.

The rail means 140 is to support the adsorption means 120 to move forward and backward and the base rail 142 is fixed to the support portion 180, and the forward and backward movement in the base rail 142 is freely coupled It is composed of a moving rail 144.

The movable rail 144 is coupled to the support bracket 126 of the adsorption means 120, and the guide member 147 and the spring 148 between the base rail 142 and the base rail 142 in the movement direction. Position and mount the fixing plate 149 so that the guide member 147 and the spring 148 are not separated from the mounted position.

In addition, the moving rail 144 is coupled to a cylinder 146 mounted in a posture that is consistent with the movement direction in a direction opposite to the direction in which the adsorption means 120 is moved, which is moved by the operation of the cylinder 146. The rail 144 advances toward the surface of the work roll 16 but returns to its original state by the force of the spring 148 when the cylinder 146 stops operating.

The operation unit 150 is mounted on the support unit 180 similarly to the cleaning unit 110, and mounts the motor 154 coupled to the clamp shaft 152 on the fixed shaft 116 and the rotating shaft of the cleaning unit 110. And the brake means 156 also coupled to the supply shaft 114 with a clamp.

The brake means 156 forms a clamp 158 coupled to the supply shaft 114 and forms a disk 160 integrated with the clamp 158, as shown in FIG. Brackets 162 are formed on both sides of the 160 to support the disk 160.

The clamp 158 may have various methods, but in this embodiment, since the cross section of the shaft is angularly cut out, the shaft of the supply shaft 114 coupled to the clamp 158 should also have a shape that matches.

The disk 160 forms a circumferential groove on the outer wall, and the pad 164 is inserted along the groove, and both ends of the pad 164 are in the same direction, and one end thereof is supported by the support 180. One end is fixed to the cylinder 166 by forming a screw portion.

Accordingly, the brake means 156 retracts the cylinder 166 such that the wiper 112 is supplied from the supply shaft 114 to the fixed shaft 116 so that the rotation of the supply shaft 114 does not proceed any further. Tension force is generated in the wiper 112 while tightening the disk 160 with the pad 164.

The support unit 180 forms a mounting plate 182 on which the above-described cleaning unit 110 and the operation unit 150 are mounted, and forms a pedestal 184 under the mounting plate 182, and the mounting plate ( The cylinder 186 is mounted in both longitudinal directions between the 182 and the pedestal 184, and the guiders 188 are mounted on both sides in the width direction of the cylinder 186.

Therefore, the support unit 180 operates the cylinder 186 to adjust the height of the cleaning unit 110 according to the position of the work roll 17.

FIG. 6 shows an operating state of the roll cleaning apparatus shown in FIG. 3, FIG. 6A shows a reverse state, and FIG. 6B shows a forward state, that is, a working state.

Referring to FIG. 6A, the cylinder 146 of the cleaning unit 110 does not operate so that the adsorption means 120 is separated from the work roll 16 so that the surface of the work roll 16 cannot be cleaned.

Referring to FIG. 6B, when the surface of the work roll 16 needs to be cleaned, the cylinder 146 of the cleaning unit 110 is operated to advance the adsorption means 120 to move the wiper 112 to the work roll 16. In order to contact the surface of the), the degree of contact between the wiper 112 and the work roll 16 is maintained in a non-strong state so that foreign matter does not cause a wound on the surface of the work roll 16.
