VERFAHREN UND VORRICHTUNG ZUM ENTFERNEN DER SCHLACKENANSAETZE AN SCHMELZ- ODER GIESSGEFAESSEN

摘要

The device for removing incrustations from the inner wall of a cylindrical vessel comprises a driven shaft supported for rotation in the vessel about its central axis and for a vertical movement along this axis. Impact tools, preferably in the form of prismatic blocks defining a straight edge, are attached respectively to the shaft by a pair of chains in such a manner that the abrading edge of each tool extends parallel to the central axis when the chains are straightened by the centrifugal force.
