本考案はデスケーリング装置に関するものであ
る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a descaling device.
熱間圧延過程において圧延材表面に生ずるスケ
ールの除去手段として、高圧水デスケーリング装
置が多く用いられている。 A high-pressure water descaling device is often used as a means for removing scale generated on the surface of a rolled material during the hot rolling process.

圧延材１に対向する側に圧延材１の幅方向に所定
のピッチで複数個の噴射ノズル５，５′を取付け
ていた。 Conventionally, as shown in Figs. 1 and 2, jet headers 3 and 3' are installed above and below between the table rollers 2 that convey the rolled material 1, and both ends are supported by fixed frames 4 and 4'. A plurality of injection nozzles 5, 5' are installed at a predetermined pitch in the width direction of the rolled material 1 on the side of the injection headers 3, 3' facing the rolled material 1.

いる。 The installation pitch of the injection nozzles 5, 5' and the position of the injection headers 3, 3' from the upper and lower surfaces of the rolled material are as follows:
It is determined that the spray is applied to the entire surface of the rolled material in the width direction, and the spray pattern of the sprayed water on the upper and lower surfaces of the rolled material is as shown in FIG.

ラツプ部分があることによつて下記のような不都
合が生じる。 That is, in FIG. 3, part A is a part where the sprays of adjacent injection nozzles overlap. The spray pattern varies depending on the manufacturing precision of the nozzle tip and wear during use, so in order to remove scale from the entire surface in the width direction of the rolled material, the spray pattern should be made to wrap as shown in part A above. There must be. However, in a hot rolling line for strip steel where descaling is performed just before the rolling mill, the presence of this spray lap causes the following inconveniences.

ているのが実状である。 That is, in the case of a rolled material, this lap portion is cooled more than other portions, resulting in a local difference in hardness. In addition, this lap portion occurs at a predetermined pitch in the width direction of the rolled material and extends over the entire length of the rolled material in the longitudinal direction. part) is always rolled at the same position on the roll, and wear of the roll surface is accelerated compared to other parts. The actual situation is that the resulting unevenness on the roller surface is transferred to the rolled material and has an adverse effect on the cross-sectional profile.

大きなスペースが必要である。 In order to solve the above problem, in Utility Model Application Publication No. 51-107816, the injection header itself is reciprocated in the width direction of the rolled material to form a wave-like subcooled portion on the rolling material, and the rolling mill A method has been proposed to equalize this supercooled portion with respect to the work roll when it is caught, but this method consumes a large amount of power in order to counteract the high pressure water flowing into the injection header. A drive is required and the device itself requires a large amount of space.
