Abstract

The invention relates to a high-pressure water descaling system. A descaling device comprises a descaling room, an upper surface descaling mechanism, an inner hole descaling mechanism, an outer surface descaling mechanism, a descaling car and a water return channel, wherein one side of the descaling room is provided with a descaling room door, and the bottom of the descaling room is provided witha pair of parallel steel rails; the upper surface descaling mechanism is arranged on the top of the descaling room close to the descaling room; the inner hole descaling mechanism is arranged on the top of the descaling room away from the descaling room door; the outer surface descaling mechanism is arranged in the descaling room opposite to the descaling room door; each surface descaling mechanism respectively comprises descaling spray heads connected respectively through hydraulic transmission; the descaling car is arranged on the parallel steel rails at the bottom of the descaling room and moved left and right between the descaling room door and the outer surface descaling mechanism along the steel rails; a rotating disk is fixedly arranged on the descaling car; and the water return channel is arranged on the lower part of the descaling room and connected with a water circulation pipeline. The system can simultaneously descale an inner surface, an outer surface and an upper surface,has good descaling effect, high speed and better social and economic values and is suitable for generalization and application.

Description

technical field [0001] The invention relates to a hydraulic descaling device, in particular to a high-pressure water descaling system for removing the oxide layer on the surface of a hot steel ingot. Background technique [0002] High-pressure water descaling is a key technology in modern hot-rolled steel control technology. It adopts the principle of high-pressure jet cutting, sprays high-pressure water through the nozzle, and produces strong scouring force and cooling force when the high-pressure water is sprayed out (the shear force generated by the base material of the rolled material and the iron oxide layer due to the different cooling shrinkage, And the steam expansion and bursting caused by water infiltration between the matrix material and the iron oxide scale) hit the surface of the billet to break the iron oxide scale into small fragments and quickly separate from the surface of the matrix. Furnace raw scale produced during heating and regenerated scale produced ...
