High-speed wire spray cooling device

The utility model belongs to the technical field of high-speed wire rods, and particularly relates to a high-speed wire rod spray cooling device which comprises a spray main pipe, spray branch pipes and a spray protective cover used for preventing spray water from splashing out of a wire rod scattered coil cooling line. The spraying main pipe is arranged in the running direction of the scattered coil wire rod and erected above the wire scattered coil cooling line. The spraying main pipe is communicated with an external water supply pipeline, a plurality of spraying branch pipes are connected to the spraying main pipe, and all the spraying branch pipes are located in the spraying protective cover. Spraying cooling is adopted to replace or compensate cooling of a cooling fan of the loose roll cooling line, and the cooling capacity of the loose roll cooling line can be greatly improved; the temperature of the coil can be quickly reduced to the phase change temperature under the conditionthat the spinning tempera
