Abstract

The invention discloses a centrifugal supergravity orientation casting system and method with a partitioned heating function. The centrifugal supergravity orientation casting system with the partitioned heating function comprises a hanging cup, a heating device, a crucible device and a heat insulation device. The hanging cup is internally provided with the heat insulation device, the heat insulation device is internally provided with the heating device, and the heating device is internally provided with the crucible device. The two sides of the top of the hanging cup are provided with liftinglugs, and the hanging cup is suspended on the end portion of a rotating arm of a supergravity centrifugal machine in a hinged manner through the lifting lugs on the two sides. According to the alloy type, the material types of an upper heating body, a lower heating and a crucible are determined, a building system is installed, a ground power supply system is connected, centrifugal machine dynamicbalancing testing is carried out, and directional solidification is carried out. According to the centrifugal supergravity orientation casting system and method with the partitioned heating function,a supergravity directional solidification function is achieved through a power reducing method, the key problem that in the supergravity directional solidification process, the temperature gradient ishard to control is solved, the cooling speed and the temperature gradient are adjustable and controllable, the structure is compact, and safety is high.

Description

technical field [0001] The invention relates to the technical field of material preparation and directional solidification, in particular to a centrifugal supergravity directional melting and casting system and method with zone heating function. Background technique [0002] As one of the key components of the hot end parts of aero-engines and gas turbines, the working blades of high-pressure turbines are the rotating parts with the worst working conditions in the engine under the coupled loading conditions of high temperature, high pressure, high speed, and alternating load for a long time. Its use reliability directly affects the performance of the whole machine. In the development process of superalloys, technology plays a great role in promoting the development of superalloys. Usually, in order to improve the comprehensive mechanical properties of superalloys, two ways are adopted: one is to add a large amount of alloying elements, and through a reasonable heat treatmen...
