Abstract

The invention relates to a device and method for high-throughput, continuous and rapid preparation of an alloy sample. The device comprises a rotating system, a dispensing system, a heating and melting system, a cooling and solidifying system, a sampling system and a PLC control system; a dispensing zone, a heating and melting zone, a cooling and solidifying zone and a sampling zone are located ona rotating table. A container placed above the dispensing zone is controlled by the PLC and dispenses the alloy to a crucible which is rotated to the zone according to a preset alloy distribution ratio; a melting cavity and a cooling device respectively placed above the heating and melting zone and the cooling and solidifying zone are respectively used for melting and solidifying the alloy in thecrucible; a sample push-out device placed under the sampling zone is used for taking out the solidified sample from the crucible. According to the device and method for high-throughput, continuous and rapid preparation of an alloy sample, a circular-type alloy sample preparation integrating heating and melting, cooling and solidifying, sampling can be realized on the rotating table. The device iscompact in structure and high in automation degree, the time for raw material dispensing, multi-furnace smelting and preparation is shortened, and high-throughput, continuous and rapid preparation ofthe alloy sample can be realized.

Description

technical field [0001] The invention relates to the technical field of alloy preparation, in particular to a high-throughput device and method for continuously and rapidly preparing alloy samples. Background technique [0002] Metal materials are widely used in military and civilian fields, and the demand is huge. However, the research and development of metal materials can be simply summarized as a "trial and error method", that is, based on existing theories or experiences, a prediction range is given for the composition ratio of the target material, followed by small batch preparation, and then based on the characterization of the prepared samples As a result, the composition is adjusted and optimized, and the preparation and characterization are carried out again. After many cycles, the target material can finally be obtained. The "trial and error" method has a long cycle and high cost, which has become a bottleneck restricting economic and social development and technol...
