MANIPULATOR FOR REPLACING SUBMERSIBLE BUCKET ON SLAB MACHINE FOR CONTINUOUS CASTING OF BILLETS Russian patent published in 2017 - IPC B22D41/56 

FIELD: metallurgy.

SUBSTANCE: manipulator contains mechanisms for replacing and cleaning of spent submersible bucket. The kinematic circuit of replacement mechanism provides movement of replaceable submersible bucket along the given path to the teeming device of the intermediate ladle. The replacement of buckets without interruption of metal flow is carried out by a hydraulic cylinder mounted on manipulator platform. Cleaning of spent submersible bucket is carried out by the mechanism containing a hollow beam (25), two horizontal jaws (26, 27) mounted thereon, a gear wheel (29), gear-satellite (30) resting on the jaws and interacting with the gear wheel, a horizontal shaft (34) mounted on the bearing support and actuated by the hydraulic cylinder. The submersible bucket removal mechanism provides simultaneous translational and two rotary movements.

EFFECT: increased yield of continuously casted billet due to shortened length of section which forms during the replacement of used submersible bucket at full mechanisation of the operation of quick replacement the submersible bucket.
