Abstract

1328036 Quenching apparatus VEREINIGTE OSTERREICHISCHE EISEN-UND STAHLWERKE A G 22 Nov 1971 [30 Nov 1970] 54152/71 Heading C7N An apparatus for preventing distortion of rotational symmetrical work pieces during quenching consists of a series of rotatable rollers fixed so that they converge towards a common axis 4, the rollers supporting a work piece so that after the engagement of adjustable rollers 10 and 11, associated with each roller 1, the work piece may be sprayed with a quenching liquid and any resulting distortion may be countered by the rollers 10 and 11. The position of the roller 11 is governed by a spindle 32, and that of roller 10 by the position of the carriage 9, itself adjustable radially of axis 4 by a rod 25 and a hydraulic cylinder 20. The quenching liquid is supplied from an annular conduit 15 and directed on to the work piece by slewable tubes 12, tubes 18 and a water container 33. Where the workpiece is held stationary, the rollers 1 and carriages 9 are rotated about the workpiece and axis 4. A central supporting roller may act within the area of the boiler centre M and further rollers may be added to support the workpiece.
