Latest Patents

Kirihara's latest patents include a method and apparatus for continuous casting of metals. This innovative technique involves applying a non-moving, vibrating magnetic field to molten metal within a casting mold. The application of this magnetic field imposes only vibration on the molten metal, resulting in a cast slab that is less susceptible to flux entrainment, bubble capture, and non-metal inclusions near the surface. The magnetic field is generated by arranging electromagnets on both sides of the mold and supplying a single-phase AC current, which operates at a frequency of 0.10 to 60 Hz. Additionally, a static magnetic field can be applied intermittently to enhance the quality of the cast slab, ensuring it is substantially free from surface segregation and flux entrainment.

Career Highlights

Tadasu Kirihara is currently employed at JFE Steel Corporation, where he continues to develop and refine his innovative casting techniques. His work has been instrumental in advancing the field of metallurgy and improving production processes within the steel industry.
