Title: Yoichi Hirose: Innovator in Centrifugal Casting Technology
Introduction
Yoichi Hirose is a prominent inventor based in Saitama, Japan. He has made significant contributions to the field of casting technology, particularly through his innovative methods and apparatuses. With a total of 17 patents to his name, Hirose has established himself as a key figure in the advancement of materials engineering.
Latest Patents
Hirose's latest patents include a centrifugal casting method, a centrifugal casting apparatus, and a cast alloy produced by the same. This invention relates to a casting method that employs rapid solidification of metals and rare-earth metals. The centrifugal casting method involves pouring a molten material onto a rotary body, which then sprinkles the molten material due to its rotation. The sprinkled molten material is deposited and solidified on the inner surface of a rotating cylindrical mold. Notably, the axes of rotation of the rotary body and the cylindrical mold are not parallel, which allows for a decrease in the average deposition rate. This innovative approach suppresses the generation of the dendritic αFe phase and segregation phases of manganese, resulting in a high-performance R-T-B-type rare-earth magnet alloy.
