Title: Kunji Yamamoto: Innovator in Vacuum-Suction Degassing Technology
Introduction
Kunji Yamamoto is a notable inventor based in Tajimi, Japan. He has made significant contributions to the field of materials processing, particularly through his innovative vacuum-suction degassing apparatus. With a total of four patents to his name, Yamamoto's work has advanced the efficiency of gas removal from molten materials.
Latest Patents
Yamamoto's latest patents include two variations of a vacuum-suction degassing apparatus. The first apparatus involves a vessel that stores a melt, with a lower half portion of a rod-formed porous member immersed in the melt. This porous member is designed to be permeable to gas while remaining impermeable to melts such as molten metal, slag, and matte. When placed in a decompression container, the portion of the porous member above the melt is subjected to vacuum or reduced pressure. This allows gases in the melt to pass through the porous member and be released into the vacuum, effectively removing gas-forming components from the melt.
The second apparatus also features a degassing member with a cylindrical form, where the lower half is immersed in the melt. This section is made of a porous material that allows gas to pass while preventing the melt from escaping. By creating a vacuum within the degassing member, gas-producing components in the melt are drawn through the partition member and separated from the melt. Additionally, the degassing member can be rotated or moved to stir the melt, enhancing the efficiency of gas removal.
Career Highlights
Throughout his career, Kunji Yamamoto has worked with various companies, including Tokyo Yogyo Kabushiki Kaisha. His innovative approaches have positioned him as a key figure in the development of advanced materials processing technologies.
