The present invention relates to a high pressure water spray device, comprising: a pipe part separated from a rolling material in a rolling process, installed in a widthwise direction of the rolling material, and taking high pressure water inside; an inducing part stored in the pipe part to be separated from an inner surface of the pipe part, including an inflow opening, and taking the high pressure water of the pipe part through the inflow opening; and a plurality of nozzle parts connected to the inducing part to be extended towards the rolling material through the pipe part. The high pressure water, taken into the pipe part, is taken into the inducing part through the inflow opening, and is sprayed to the rolling material through the nozzle parts. The high pressure water spray device is capable of reducing foreign substances, contained in the high pressure water and sprayed with the high pressure water, and preventing high pressure water from staying on the rolling material. |
