The invention discloses a large-scale split vertical spraying and quenching machine tool that comprises a fixed bed body thereof. The fixed bed body takes the shape of a vertical barrel, one side of which is provided with a workpiece access door from top to bottom along longitudinal direction and a movable bed body of the machine tool suitable for the access door in size, wherein one side of the movable bed body is articulated with the fixed bed body, the movable bed body is connected with a bed body opening and closing mechanism, can be unscrewed at a certain angle under the action of the bed body opening and closing mechanism and can be translated to the quenching machine tool after a workpiece is discharged from a furnace (matching with an opening and closing furnace); a spraying and quenching cavity surrounded by the fixed bed body and the movable bed body is internally provided with a water spraying mechanism, a mist spraying mechanism, a wind spraying mechanism and the like and can carry out spraying and quenching process of necessary technology on workpieces. The machine tool can be used for comprehensive quenching technology of long-axis pieces such as rotors, and a processed long-axis piece is uniform in the entire hardness from top to bottom, high in grain size number, good in obdurability and high in comprehensive mechanical performance.
Description
technical field [0001] The invention relates to a spray quenching machine tool, in particular to a large split vertical spray quenching machine tool used for the comprehensive quenching process of long shaft parts such as rotors. Background technique [0002] The rotors of nuclear power generators and steam turbines need to bear large centrifugal force and additional stress due to their large size, length, weight, and high-speed rotation during operation. At the same time, they work under high temperature and high pressure, and are subject to complex forces such as alternating loads. The rotor material is required to have good comprehensive mechanical properties at room temperature, high temperature tensile strength, good toughness and comprehensive mechanical properties. The rotor materials of nuclear power generators mainly include 30Cr2Ni4MoV and 26NiCrMoV115 steel, etc., and the performance heat treatment includes quenching heating + water spray quenching or spray coolin...
