Title: Xiaolei Rao: Innovator in Rare Earth Alloys and Motor Technology
Introduction
Xiaolei Rao is a prominent inventor based in Beijing, China. He has made significant contributions to the fields of rare earth alloys and motor technology. With a total of 6 patents to his name, Rao's work showcases his innovative spirit and technical expertise.
Latest Patents
Rao's latest patents include a method for preparing fine grain rare earth alloy cast strips and a rotary cooling roll device. The preparation method involves a melting process where the power of an induction melting furnace is controlled to perform a cyclic heat treatment. This process ensures that the alloy raw material is completely melted before reaching a surface temperature of 1300° C. After melting, the power is adjusted to stabilize the surface temperature between 1400° C. and 1500° C. The casting cooling process then cools the melt on a rotary cooling roll, producing an alloy cast strip with a controlled surface linear velocity of 1.5 m/s to 2.25 m/s. Additionally, he has developed a motor rotor that includes an iron core with embedded magnets, designed to enhance motor efficiency.
