The invention relates to the technical field of high-temperature
alloy preparation, and particularly discloses a vacuum melting control method for
rare earth elements Y, La and Ce in high-temperature
alloy, and the method comprises the steps of S1, high-temperature
alloy preparation, S2,
rare earth element addition, S3, ultrasonic uniform distribution, S4,
spectral analysis and S5, uniform cooling. After the high-temperature alloy is prepared, the
rare earth elements are prepared into particle shapes through
ball mill equipment, the rare earth elements are accurately controlled through a microfluid
system, it is ensured that the rare earth elements are evenly added into the alloy, the particle-shaped rare earth elements are more easily dissolved and evenly dispersed into the high-temperature alloy,
argon is introduced into a furnace body for protection, and the high-temperature alloy is obtained. The rare earth elements can be prevented from being burnt, the rare earth elements can be evenly and fully mixed with the high-temperature alloy through the ultrasonic equipment, the local concentration difference of the rare earth elements can be reduced, the uniformity of the alloy is improved, and the quality and performance of the alloy are improved.
