Title: The Innovative Mind of Ritsuo Hashimoto: A Pioneer in Continuous Casting Technology

Introduction

Ritsuo Hashimoto, an esteemed inventor hailing from Hiroshima, Japan, has made significant contributions to the field of metallurgy through his innovative inventions. With a remarkable portfolio of eight patents, Hashimoto has focused primarily on advancements in continuous casting technology, leading to enhancements in efficiency and quality in metal production.

Latest Patents

Among his latest patents, Hashimoto has developed two groundbreaking technologies. The first is a **dual drum type continuous casting device and method for continuous casting**. This twin-drum apparatus is designed to cast a metal sheet by supplying molten metal to a specially designed pouring basin formed by a pair of cooling drums that rotate in opposite directions. By cooling the molten metal through contact with these rotating surfaces, Hashimoto's invention ensures the formation of a solidified shell. A significant feature of this device is its mechanism to mitigate adverse effects caused by thermal expansion differences during the casting process, ultimately enhancing the reliability and quality of the castings produced.

Another notable invention is the **steel plate splicing facility utilizing shear joining**. This facility incorporates a steel plate heating apparatus that retrieves and heats overlapping steel plates before clamping their ends together. Using a shear-joining apparatus, the tail end of one steel plate and the leading end of another are clamped and sheared, forming new surfaces that are joined at high temperatures (equal to or exceeding 350°C) while maintaining tight tolerances. This innovative method showcases Hashimoto's expertise in improving steel joining techniques, promoting stronger connections between plates.
