Problems solved by technology

[0003] However, the melting and casting system of existing high-gravity melting and casting equipment has no heating function, and can only be cooled with the furnace. The solidification process is uncontrolled, and the samples are small, so only composition optimization can be performed, and performance testing cannot be performed. Therefore, composition optimization based on high-gravity technol

Abstract

The invention discloses a centrifugal supergravity casting and directional solidification system. A rotor system and a lower drive type main shaft complex are installed in an experiment cavity, the bottom of the experiment cavity is installed on the device base in a buffering mode, a centrifugal main machine is installed on the experiment cavity and connected with the lower drive type main shaft complex, the lower drive type main shaft complex is connected with the rotor system, and a lifting system is located above the experiment cavity and connected with the experiment cavity cover. A directional casting system is arranged in a hanging cup, a heat preservation device is arranged in the hanging cup, a heating device is arranged in the heat preservation device, a crucible device is arranged in the heating device, and the hanging cup is hung at the end of the rotating arm of the supergravity centrifugal machine through lifting lugs on the two sides in a hinged mode. The supergravity directional solidification function is achieved through a power reduction method in the centrifugal supergravity environment by carrying the high-temperature melting and casting furnace or the directional melting and casting furnace, the key problem that the temperature gradient is difficult to control in the supergravity directional solidification process is solved, operation is convenient, and safety and reliability are achieved.

Description

technical field [0001] The invention relates to a high-gravity material preparation device in the technical field of material preparation and directional solidification, in particular to a centrifugal high-gravity casting and directional solidification device. Background technique [0002] Usually, in order to improve the comprehensive mechanical properties of the alloy, two ways are adopted: one is to add a large amount of alloying elements, and through a reasonable heat treatment process to produce solid solution strengthening, precipitation strengthening and grain boundary strengthening, etc., so as to ensure that the alloy has properties from room temperature to Good strength at high temperature, indicating stability and good plasticity; the second is to start with the solidification process and adopt the directional solidification process to prepare the columnar grain structure with grain boundaries parallel to the principal stress axis to eliminate harmful transverse gr...
