Abstract：

The online hot descaling system was used to remove surface skin scales before precision forging so as to ensure processing quality. The principle of high pressure water descaling system was introduced in detail. Design and calculation of technology parameters of high-pressure water descaling system which used for hot rolling circle steel billets mainly including the jet pressure, nozzle parameter, arrangement mode of nozzle, impact force of workpiece surface, reasonable selection of shoot distance, parameters of pump and descaling pipes and so on were introduced. The actual test shows that the removal rate of workpiece surface skin scales reaches almost 100% and decreased range of the temperature is 2 to 5 ℃, which meets the requirement of precision forging.
