METHOD OF CLEANING AND/OR REMOVAL OF SCALE FROM FLAT WORKPIECE OR ROUGH STRIP BY SCALES WATER DESCALING AND DEVICE FOR SCALES WATER DESCALING Russian patent published in 2017 - IPC B21B45/08 

FIELD: metal processing.

SUBSTANCE: present invention relates to rolling. Method of scales water descaling from flat workpiece or rough strip (1) surface is performed using scales water descaling device (2), which has at least one nozzle (3) with outlet channel, directed towards flat workpiece or rough strip (1) surface, through which water under pressure (p) is supplied onto flat workpiece or rough strip (1) surface. Improving scales water descaling conditions and increasing process costs saving due to, that water is supplied through nozzle (3) outlet channel (4), made in direction (N), perpendicular to flat workpiece or rough strip (1) surface, rectangular or slit-shaped at least on some sections with arc-shaped transition, with nozzle (3) outlet channel (4) width (b) in direction (F) of flat workpiece or rough strip (1) transporting, making 0.2–1.5 mm, wherein water is supplied along flat workpiece or rough strip (1) surface entire width (B) in form of continuous strip jet (5) with observing distance (a) between nozzle (3) outlet channel (4) and flat workpiece or rough strip (1) surface, making 8–50 mm, wherein water is supplied into nozzle (3) under pressure (p), making 5–50 Bar.

EFFECT: device for scales water descaling comprises appropriate equipment.
