STEEL-PLATE DESCALING DEVICE
The invention relates to a steel-plate descaling device, including several steel-plate surface descalers and several steel-plate side-surface descalers disposed along the direction of a flow line as well as a trolley rail disposed in parallel to one side of the flow line. At least one roller-changing vehicle slides back and forth on the rail. The roller-changing vehicle is provided with a roller-changing mechanism. When the roller-changing vehicle slides to a front side of the steel-plate surface descaler, the roller-changing mechanism extends into the inner part of the steel-plate surface descaler to change the roller. The oxide scale of the steel-plate surface is removed physically, having low pollution and high descaling efficiency without a blind spot, and simultaneously having a high degree of automation in replacing the descaling roller through the roller-changing vehicle, saving both time and effort.

REDUCTION AND REMOVAL OF PROCESS OXIDES ON STAINLESS STEEL
Oxides formed during annealing of stainless steel strip are removed with abrasive brushes, in lieu of acid or molten salt based pickling. In some embodiments, the stainless steel strip is treated with a rare earth element or a related transition metal before annealing, and then brushed after annealing to remove any oxides. The selection of brushes can impart a finished appearance to conventionally polished stainless steel.
Method and device for descaling metal wire
Provided are a method and a device for descaling that make it possible to effectively remove oxide scale from the surface of a metal wire. The descaling includes spraying the surface of a metal wire (W) with a mixture (9) of water and hard particles from a plurality of nozzles (8). The plurality of nozzles (8) include a plurality of self-cleaning nozzles that spray at a spray angle () of 90 or smaller with respect to the metal wire (W). The spray angle () is the angle formed by the central axis (X) of the spraying and a vector (Vt) indicating a conveyance direction that originates at the intersection (P) of the central axis (X) and the metal wire surface.
