Abstract

1353336 Quenching tank SKF INDUSTRIAL TRADING & DEVELOPMENT CO BV 2 Sept 1971 [2 Sept 1970] 41072/71 Heading C7N [Also in Divisions F3-4] Work pieces e.g. bearing rings discharged from a tempering furnace 10 through a shoot 11 on to an openwork conveyor belt 15 in a quenching tank 12 are cooled evenly by passing through a flush chamber 13 contained within said tank, passage of cooling fluid through said chamber and said conveyer being constantly reversed. The reversal paths shown in Fig.2 are effected by propellers 24 actuated by motors 50 and the conveyer passes between perforated plates 19, 20 co-operating with similar plates 21, 22 moved by a lever 23 to control the flow velocity of the fluid. A second conveyer 26 with carrier members 27 assists the work pieces up inclined portion 18 of the conveyer 15.
