High-pressure water descaling nozzle arrangement device

The utility model relates to the field of hot rolling production line high-pressure water descaling, in particular to a high-pressure water descaling nozzle arrangement device, which comprises nozzles, high-pressure water pipelines and a hot steel plate blank, the nozzles are uniformly arranged on the high-pressure water pipelines, the high-pressure water pipelines are arranged above and below the hot steel plate blank, and the nozzles are arranged in a completely consistent manner. The deflection angle of each nozzle in the horizontal direction is in the same straight line, and the deflection angle is 0 degree. After the structure is adopted, the residual defect rate of stripe-shaped iron oxide scales on the surface of a steel plate blank on a 2250 production line of a Taihi steel hot continuous rolling factory is reduced to below 3% from 20%. 本实用新型涉及热轧生产线高压水除鳞领域，高压水除鳞喷嘴布置装置，包括喷嘴、高压水管道、热钢板坯，高压水管道上均匀设置有喷嘴，热钢板坯的上方和下方均设置有高压水管道，每个喷嘴的布置均完全一致，每个喷嘴的水平方向偏转角均在一条直线上，偏转角均为0°。本实用新型采取上述结构后，太钢热连轧厂2250生产线钢板坯表面条纹状氧化铁鳞残余缺陷率由
