Description

Wiper protection device for work roll cooling water blocking of rolling equipment

The present invention is to prevent the coolant sprayed to cool the roll during the rolling operation while passing the rolled material between the work roll for slab rolling of the rolling mill to prevent it from falling to the top of the rolled material. The present invention relates to a wiper, and more particularly, to a wiper protection device for blocking work roll cooling water of a rolling mill, which can prevent damage to the work roll by radiant heat even when the wiper contacts the work roll.

In general, as shown in FIG. 1, the cooling water sprayed from the cooling water header 2 to cool the work roll 10 which is prevented from being deformed by a back up roll 11 in a rolling facility is formed in the upper portion of the rolled material. The wiper 4 is installed close to the work roll 10 in order to prevent falling into the work roll 10.

The wiper 4 is mounted at the end of the main body 1 which is operated back and forth by the hydraulic cylinder 9, and the main body 1 is advanced so that the wiper 4 is brought into close contact with the work roll 10 to cool the water header 2 The cooling water sprayed from is prevented from falling to the upper part of the rolled material.

However, such a wiper (4) is conventionally exposed to the radiant heat of the rolled material, so that the wiper is burned by the radiant heat, so that the thickness of the wiper decreases or the contact surface with the work roll (10) is reduced, or bending occurs in the contact surface, thereby cooling the work roll (10). It was not possible to completely block the falling of the cooling water to the top of the rolled material has a problem that not only the poor quality of the rolled material occurs, but also shortened the life of the wiper.

The present invention is made to solve the problems of the prior art as described above, to prevent the burning of the wiper by blocking the radiant heat from the rolled material to extend the life and to completely block the falling of the work roll cooling water to the rolled material It is an object of the present invention to provide a wiper protection device for blocking work roll cooling water of an attached rolling equipment.

The wiper protection device for the work roll cooling water blocking device of the rolling equipment of the present invention for achieving the above object moves forward and backward to adjust the degree of exposure to radiant heat from the rolled material of the wiper 4 mounted on the wiper body 1. The wiper guide 8, a high heat resistant heat sink 12 mounted below the wiper guide 8 to block the wiper from the radiant heat of the rolled material, and the heat sink 12 to prevent the heat sink 12 from contacting the work roll 10. A pair of stoppers 5 adjustablely mounted on top of the guide 8 and a pair of clamps mounted on the wiper body 1 to prevent the guide 8 from disengaging from the wiper body 1. It is a structure characterized by including (15).

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing preferred embodiments.

As shown in Fig. 2 and 3, the wiper protection device of the present invention is a wiper guide (8) to which the wiper body (1) equipped with the wiper (4) is coupled forward and backward, and mounted on the lower part of the wiper guide and rolled A heat sink 12 which blocks the wiper from the radiant heat of the material, and a pair of stoppers 5 which are adjustablely mounted on the guide 8 to prevent the heat sink 12 from contacting the work roll 10; And a pair of clamps 15 mounted on the wiper body 1 to prevent the guide 8 from being separated from the wiper body 1.

In more detail, the wiper guide 8 includes a lower plate 8a having a heat sink 12 mounted on the lower portion with bolts 13 and a U-shaped rail portion 8b on both sides thereof. 8b) The stopper 5 is assembled with the bolts 5a so as to be adjustable in position thereon.

Bolts 8c are installed at both sides of the rail portion 8b of the wiper guide 8 so as to be coupled to the spring guide 7 mounted on the bent side of the wiper body 1, and the spring guide 7 Each of the springs 7a is incorporated therein so that the wiper body 1 is easily movable between the idle rollers 14 symmetrically mounted on the upper and lower surfaces of the inner side rail portions 8b of the wiper guide.

The stoppers 5 respectively assembled on the upper portion of the rail portion 8b of the wiper guide are made of the same material as the wiper 4 so as not to damage the surface of the work roll when closely attached to the work roll 10, and to improve adhesion. It is thicker than the wiper 4. In addition, the bolt 5a is engaged to protrude by the predetermined interval A in the work roll direction than the wiper 4, but the wiper 4 is changed by changing the position of the heat sink 12 by changing the assembly position of the stopper 5. You can adjust the degree to which is exposed to radiant heat. Further, by making the thickness of the stopper 5 larger than the thickness of the wiper 4, the amount of wear of the stopper 5 is brought into close contact with the work roll only by the elastic force of the spring 7a and is less than that of the wiper 4 which is brought into close contact with the hydraulic cylinder. The interval A can be maintained at all times.

In the present invention, the heat dissipation plate 12 mounted on the lower plate 8a of the wiper guide is formed to always surround the lower part of the wiper 4 as the guide 8 moves forward and backward, so that it can withstand high temperature radiant heat from the rolled material. Made of heat resistant material.

In the present invention, the wiper 4 is bolted to the upper surface of the work roll side end of the main body 1, and the main body 1 to prevent the guide 8 from being separated from the spring guide 7 from the wiper main body 1. Guide clamps 15 are mounted on both rear ends.

In the present invention, as shown in FIG. 1, the hydraulic cylinder 9 is attached to the wiper main body 1 so that the wiper main body 1 is brought into close contact with the work roll.

Hereinafter will be described the operation of the work roll cooling water blocking wiper protection device of the rolling equipment of the present invention configured as described above.

When the wiper main body 1 is moved forward with the hydraulic cylinder 9, the stopper 5 comes into close contact with the work roll first, and the wiper guide 8 moves backward so that the spring 7a contracts. When the contraction of the spring 7a is completed, the wiper 4 is completely in contact with the work roll, and the heat sink 12 is wrapped around the lower part of the wiper 4 while maintaining the distance A from the work roll. 4) Protect.

In addition, when the wiper main body 1 is retracted with the hydraulic cylinder 9, the stopper 5 is separated from the work roll, and the spring 7a is expanded to move the wiper guide 8 and the heat sink 12 forward.

Therefore, according to the present invention as described above, when the stopper 5 is in close contact with the work roll, the degree of exposure from the rolled material of the wiper 4 is adjusted according to the forward and backward movement of the heat sink 12 to prevent the wiper from burning. It is possible to extend the life of the wiper and to improve the adhesion of the wiper to the work roll, so that the cooling water can be completely prevented from falling to the top of the rolled material.
