Description

[0001] Apparatus for cleaning casting roll [0002]

The present invention relates to a casting roll cleaning apparatus, and more particularly, to a casting roll cleaning apparatus for loading a casting roll with a brush roll to clean the casting roll.

In general, a method of casting a thin plate includes a continuous casting method in which a slab is manufactured by a continuous casting method using a molten steel through a tundish, followed by rolling and finishing to form a thin plate, and a casting roll There is a twin roll thin sheet casting method in which a thin sheet is directly manufactured without rolling and finishing the slab.

Such a twin roll casting machine (hereinafter referred to as a " twin roll casting machine ") is schematically shown in FIG.

1, molten steel M in the container 110 is injected through a nozzle 112 between a pair of casting rolls 120 rotating in the opposite direction of cooling, And the solidified shell is pressed down to be produced as a thin plate (slab) S. That is, when the molten steel M is supplied between the two casting rolls 120 rotating at a constant speed, the molten steel M forms a solidifying angle while contacting the casting roll 120, The thin plate S is formed at the roll contact point. At this time, the end of the casting roll 120 is provided with a dam 130 composed of a ceramic which functions as a dam to prevent the molten steel M from flowing out. The casting roll 120 has a structure in which cooling water is circulated inside the casting roll 120 and a crown for controlling the shape of the casting roll 120 is formed.

Therefore, the molten steel M is supplied from the twin-screw casting machine 100 through the nozzle 112 of the vessel, and the molten steel M supplied is solidified and pressed in the casting roll 120 to form the thin plate S, The continuously cast thin plate is fed from the pinch roll 160 via the loop pit, the atmosphere chamber 140 and the transfer table 150, and finally coiled to the coiler (not shown) via the rolling mill 170.

In the casting roll 120 of the twin-roll casting machine 100, a brush roll 210 is used which removes foreign materials on the casting roll surface while rotating and rubbing, that is, cleaning the casting roll.

For example, the oxidation scale of the molten steel (M), which is a contaminant generated on the surface of the casting roll 120, or manganese, which is a vaporizing component in the molten steel, is oxidized and deposited on the surface of the roll in the form of manganese oxide, The brush roll 200 is used to remove the coating on the surface of the casting roll 120 and a plurality of the casting rolls 120 are arranged .

However, if foreign matter such as a coating on the surface of the casting roll 120 is not dropped on the brush roll 200, only the portion of the casting roll 120 corresponding to the foreign substance is locally worn There is a problem in that it occurs.

That is, since the brush roll 200 simply rotates about its longitudinal axis, it does not fall off when the brush roll 200 is attached to the surface of the brush roll 200, thereby causing local wear in the casting roll 120 .

Also, in the casting roll 120, thermal stress is generated due to thermal cycling in the casting process, and cracks are generated on the surface as heat fatigue occurs on the surface due to repetition of such thermal stress.

Meanwhile, the present invention includes a vibration means and a shot pinning means provided to the cleaning means as a main structural feature.

First, the vibrating means is installed in the cleaning means to vibrate the brush roll 210, so that foreign substances adhered to the brush roll 210 are dropped, so that the localized wear of the casting roll by the foreign- To prevent the occurrence of the problem.

That is, if foreign matter such as a film on the surface of the casting roll 120 adheres to the brush roll 210, the region of the casting roll 120 corresponding to the foreign matter adhered to the brush roll 210 is locally abraded The vibration means vibrates the brush roll 210 to separate and remove the foreign matter adhered to the brush roll 210, thereby preventing this.

Such vibration means may be configured to reciprocate the brush roll 210 along the longitudinal direction.

More specifically, the brush roll 210 includes a roll shaft 211 and a brush 212 radially connected to the roll shaft 211 around the roll shaft 211. The vibration member includes a bearing member 500 And a hydraulic unit 600 for reciprocally moving the bearing member 500 in the longitudinal direction of the roll shaft 211.

The bearing member 500 has a structure in which one side of the bearing member 500 is inserted into a coupling groove 211a formed in the roll shaft 211 so that the roll shaft 211 is rotatably coupled to the bearing member 500, The roll shaft 211 reciprocally moves in the longitudinal direction, that is, oscillates. Of course, at this time, the bearing member 500 may be connected to the roll shaft 211 only if the roll shaft 211 is rotatable, but it is not limited to the present invention, and any coupling structure may be employed.

The oil pressure unit 600 is connected to the other side of the bearing member 500 and configured to reciprocate the bearing member 500 in the longitudinal direction of the roll shaft 211 by hydraulic pressure.

The hydraulic unit 600 includes a hydraulic housing 610 and a hydraulic cylinder 620. The hydraulic housing 610 contacts the longitudinally opposite side portions of the roll shaft 211 in the bearing member 500, (612) that expand and compress in the longitudinal direction of the roll shaft (211). It should be understood that the expansion members 611 and 612 are not limited to the present invention but may be any structure and shape as long as they are expanded when the hydraulic pressure is supplied and compressed when the hydraulic pressure is discharged.

The hydraulic cylinder 620 is connected to the expansion members 611 and 612 by a hydraulic connection line 631 to supply hydraulic pressure to the expansion members 611 and 612 or to supply the hydraulic pressure to the expansion members 611 and 612 And discharges the hydraulic pressure. That is, when the hydraulic cylinder 620 supplies hydraulic pressure to the expansion member 611 arranged on the left side to expand it and the hydraulic pressure is discharged from the expansion member 612 disposed on the right side to compress the expanded expansion member 611, The expansion member 612 disposed on the left side inflates the hydraulic pressure and the bearing member 500 moves to the right side. On the other hand, the hydraulic cylinder 620 inflates the inflating member 612 disposed on the right side by supplying the hydraulic pressure, The bearing member 500 is moved to the left by the inflated expansion member 612 on the right side. Such a series of movements is performed quickly, so that the reciprocating motion is realized as vibration.

The cleaning unit may include a drive unit having a rotary drive shaft 700 that is key-engaged with the brush roll 210 to rotate the brush roll 210 while passing through the roll shaft 211 of the brush roll 210.

At this time, one of the rotary drive shaft 700 and the roll shaft 211 may have a key 710 formed along the longitudinal direction and a key groove 720 through which the key 710 is inserted, The key groove 720 may be longer than the key 710 so that the roll shaft 211 is reciprocated in the longitudinal direction by the means. For reference, the keyway 720 includes a plurality of keyways 720 on both sides of the key 710 as shown in FIG.

On the other hand, the shot peening means is provided in the brush roll 210 to apply compressive stress to the surface of the casting roll as shown in FIG. 5, so that thermal stress is generated in the casting roll by the heat cycle in the casting process, It is possible to prevent cracks from being generated on the surface of the casting roll.

Specifically, the shot peening means may include a shot 900 mounted at the end of the brush 212 of the brush roll 210, so that during the rotation of the brush roll 210, As shown in the drawing, the shot 900 is rotated together with the brush 212 to strike the surface of the casting roll 120, so that there is a cleaning effect that breaks the oxide film on the surface of the casting roll 120, So that there is an effect of strengthening the strength. At this time, as the shot 900, a hardened small iron ball may be utilized as an example.

That is, the shot peening means collides the shot 900 with the surface of the casting roll 120 to generate compressive stress on the surface of the casting roll 120 as a peening effect together with a cleaning effect, thereby dramatically increasing the fatigue strength The lifetime of the casting roll 120 can be increased. For reference, a fine impact groove 120a is formed as the shot 900 is impacted on the surface of the casting roll 120. [

As shown in FIG. 7, the experimental result shows that the residual compressive stress increases as the surface of the casting roll 120 gets closer to the surface of the casting roll 120. This shows that fatigue life of the casting roll 120 is improved by shot peening Able to know. For reference, compressive stress is indicated by a (-) symbol.

As a result, according to the present invention, since the vibration means for vibrating the brush roll 210 is constituted, foreign matter is dropped from the brush roll 210 having foreign substances such as a film on the surface of the casting roll 120, It is possible to prevent the casting roll 120 from being locally abraded by the roll 210. [

Further, since the short pinning means for applying compressive stress to the surface of the casting roll 120 is constituted, the present invention can dramatically increase the fatigue strength by generating compressive stress on the surface of the casting roll 120 as a pinning effect Accordingly, the life of the casting roll 120 can be increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments. It is to be understood that various changes and modifications may be made without departing from the scope of the appended claims.
