Title: Innovations of Ryuji Watanabe: A Pioneer in Silicon Production and Metal Casting

Introduction

Ryuji Watanabe, an esteemed inventor based in Muroran, Japan, has made significant contributions to the fields of materials science and engineering. With an impressive portfolio of three patents, Watanabe has been at the forefront of innovations that enhance production processes for high-purity silicon and the efficient manufacturing of metallic products.

Latest Patents

Watanabe's latest patents showcase his expertise in developing advanced production methods. One of his prominent patents is focused on a production process and apparatus for high purity silicon. This innovative method involves heating solid silicon monoxide (SiO) within a temperature range of 1000°C to 1730°C to facilitate a disproportionation reaction. This process enables the decomposition of solid SiO into liquid or solid silicon and solid SiO, allowing for the efficient separation of produced silicon from SiO. This technology not only provides a pathway for high-purity silicon production but also emphasizes environmental considerations by optimizing the use of resources.

Another noteworthy patent by Watanabe is related to the manufacturing of strips, bars, and wire rods. This method entails the continuous supply of molten metal into an open-top endless casting groove on an annular mold that rotates around a vertical shaft. The innovation lies in the effective cooling of the molten metal from outside, ensuring uniform solidification before taking out the cast section. By utilizing a roll to maintain contact between the cast section and the groove, Watanabe's approach enhances the quality and efficiency of metal casting. The design permits multi-strand casting, allowing for simultaneous production of multiple sections, thus improving operational efficiency.
