Description
Technical Field
The invention mainly relates to the technical field of alloy casting, in particular to pre-stirring equipment before alloy solution pouring.
Background
The chemical composition of superalloys is very complex, typically containing over ten alloying elements and some inevitable impurity elements. As a new generation of precipitation strengthening nickel-based high-temperature alloy, the alloying degree of GH4720Li is very high, the sum of the contents of Al and Ti which are forming elements of a main strengthening phase gamma 'is as high as 7.5%, while the volume fraction of gamma' is increased, a (gamma '+ gamma) eutectic phase is formed at the crystal boundary of an as-cast structure due to the segregation of Ti, and the (gamma' + gamma) eutectic can be used as a crack initiation source in the deformation process, so that the deformation capability of the GH4720Li alloy is seriously influenced.
In the traditional casting, metal grows in a dendritic crystal mode under a stable state, and composition segregation and coarse dendritic crystals easily occur in the solidification process. For GH4169 alloy, the branches are rich in Nb and Ti, and the branches and the stems are poor in Nb and Ti, so that metallurgical defects such as black spots, white spots, carbide segregation and the like are easily caused. If no effective measures are taken, the serious component segregation is inherited into a material finished product to form coarse and fine crystal strip segregation and strip segregation of delta phase and gamma' phase, so that the inhomogeneity of the structure and the performance directly influences the product quality. The concrete expression is as follows: in the deformation processing process, the brittle low-melting-point phase at the crystal boundary can seriously reduce the hot processing plasticity of a casting blank, and meanwhile, the macroscopic structure nonuniformity is easy to cause deformation instability and present nonuniform deformation, so that the defects of cracks and the like are easy to generate in subsequent processing, and the product performance is reduced; in the loaded service process, the brittle phase at the grain boundary has poor deformation coordination capability, and the work hardening of the material cannot be stably maintained in the stressed deformation, so that early cracks are generated, and the performance is damaged. [2] basic research on solidification and segregation behaviors of an electroslag remelting large IN718 nickel-based alloy ingot [ D ] Beijing university of science and technology, 2020.) IN order to reduce and improve component segregation and improve uniformity of material components and structures, mechanical stirring, electromagnetic stirring, bubble stirring, mechanical vibration, ultrasonic vibration and the like are common dynamic grain refining methods IN a metal casting process, and an alloy melt is pretreated by the methods so as to achieve the purpose of controlling a solidification structure.
Mechanical stirring easily operates and adjusts conveniently, but also has some problems, for example common mechanical stirring mode makes alloy solution centrifugal separation appear easily, and the great part of proportion is thrown to the container all around, and the less part of proportion then stays at the center to aggravate the inhomogeneity of melt solidification process, rotatory speed is higher, and this kind of separation phenomenon is more outstanding, stirs to become centrifugal separation, consequently adopts traditional mechanical stirring mode to stir alloy solution not good effect.
