Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a transfer type cooling device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer type cooling apparatus and a wire material cooling apparatus including the same.

In a conventional wire rolling process, a billet is rolled in a roughing roll, a half-pitch mill, an intermediate finishing mill and a finishing mill at about φ5.5 to φ22, and wound into a helical coil in a laying head facility.

Since the rolled wire rod is at a high temperature of about 1100 ° C, the wire rod should be cooled to the proper temperature in accordance with the characteristics of the coil in the winding step of winding the wire rod. A typical coiling temperature is about 850 DEG C to 910 DEG C, and a separate cooling device is required to cool the wire to such a temperature.

However, since the wire rod in the rolling process is transported at a speed of about 110 m / s, the cooling operation of the wire rod must be performed in accordance with the characteristics of the wire rod being transported at high speed. That is, it is very important to prevent a temperature deviation due to uneven cooling in the longitudinal direction of the continuously fed wire rod. This is because a temperature deviation in the wire rod longitudinal direction may cause various defects of the finished product in the future.

On the other hand, the wire rod passed through the cooling device is subjected to a series of processes in which the outer diameter is measured by a bar gauge meter to calculate the outer diameter deviation. However, before the process, various coolants remain on the surface of the wire passed through the cooling device, and the residual coolant deteriorates the accuracy of measurement of the outer diameter of the wire.

In addition, there is a problem that the coolant flowing out to the outside of the cooling device has a problem of increasing the maintenance cost due to contamination of other nearby facilities or working environment, and may cause various safety accidents.

Hereinafter, the blowing unit 130 will be described in more detail with reference to FIG.

The blowing unit 130 of the present invention can be configured to supply the gas in a direction opposite to the conveying direction of the object 10 to more effectively remove the coolant remaining on the surface of the object.

Specifically, the first blowing block and the second blowing block may be coupled to the blowing housing such that the first blowing block and the second blowing block are separated from each other by a predetermined distance, and the space formed by separating the first and second blowing blocks may be the first interstitial space 134 .

The first gap space is connected to the gas accommodation space 135a so that the gas supplied from the gas supply header 135 can be supplied to the object 10 through the first gap space through the gas accommodation space 135a .

At this time, the first space may be provided to supply gas to the object 10, and to form a predetermined inclination so that the gas is supplied in a direction opposite to the conveying direction of the object 10. Specifically, And may be inclined in the reverse direction with respect to the conveying direction.

The inlet 132b of the first blowing block includes the linear inclined portion 132e and the outlet 133b of the second blowing block also includes the linear inclined portion 133e. However, the slopes of the respective linear inclined portions 132e and 133e are different from each other.

As shown in FIGS. 3 and 4, the linear slopes 132e and 133e have an effect of controlling the flow.

That is, the linear inclined portion 133e included in the second blowing block 133 is inclined in the opposite direction to the conveying direction of the object 10, so that the external air is introduced into the second blowing block 133 . The air introduced into the second blowing block 133 moves in a direction opposite to the conveying direction of the object 10 due to the conveyance of the object 10 and the linear inclined portion of the first blowing block 132 132e to the outside of the first blowing block 132 quickly.

This flow of outside air has an effect of helping the coolant to be removed promptly by supporting the coolant in the gas accommodation space 135a to remove the coolant. That is, the outside air introduced through the linear inclined portion 133e of the second blowing block is supplied to the linear inclined portion (not shown) of the first blowing block 132 along with the air ejected at the high pressure, 132e. The shape of the linear inclined portions 132e, 133e promotes a smooth flow, thereby discharging the coolant to the outside of the first and second blowing blocks 132, 133 more quickly.

Accordingly, the first and second blowing blocks 132 and 133 can be fixed to the blowing housing 131 by the combination of the first and second blowing blocks 133 and 133 and the coupling groove 133f is formed in the second blowing block 133, The coupling grooves 137 corresponding to the respective coupling grooves 133f and 137 are formed and then the coupling members 136 passing through the respective coupling grooves 133f and 137 are tightened.

The adjustment of the size of the first gap space 134 may be performed by adjusting the coupling between the threads 132c and 133c of the first and second blowing blocks 132 and 133 and the screw groove 131b of the blowing housing 131 It is possible.

That is, as the distance between the first and second blowing blocks 132 and 133 increases, the size of the first gap space 134 increases, and as the gap between the first and second blowing blocks 132 and 133 becomes closer, The size can be reduced. This applies equally to the first and second cooling blocks 122 and 123, which will be described later.
