DEVICE FOR HYDRAULIC REMOVAL OF SECONDARY SCALE FROM ROLLED STOCK ON ROLLING MILL Russian patent published in 1995 - IPC

FIELD: rolling of sheet stock. SUBSTANCE: one of hexagon sides rests permanently on metal strip. As stock width is changed, particularly to a larger dimension, the hexagon turns one facet thus withdrawing the used facet and putting a new facet in contact with the strip. This eliminates gaps between the strip and revolving wall of water drain. As all the facets of the hexagon become worn, the latter is replaced. This is cheaper than each time changing or repairing the revolving wall. EFFECT: reduced operational expenses and higher quality of rolled stock due to constant contact of the revolving wall with said stock irrespective of its width. 2 dwg
