Hydraulic descaling plays an important role in the surface quality of hot-rolled steel. Descaling occurs immediately before hot-rolling in order to eliminate layers of iron oxides on the surface. These oxides are called scales and form stratified layers. A hydraulic descaler consists of a row of high-pressure flat jet nozzles, i.e. descaling nozzles. Descaling nozzles are composed of several parts, one of which is the flow stabilizer. The stabilizer is an important part which attempts to minimize the turbulence of the flow within the system and contributes to the optimal performance of the nozzle. Currently, it is possible to choose from a wide variety of stabilizers according to the system operating conditions. This paper explores the influence of the length of a chosen stabilizer on the impact pressure distribution of the water flow. It was found that a longer stabilizer can significantly improve the performance of descaling nozzles. These findings can increase the performance of the descaler and reduce the production cost of hot-rolled steel.
