Title: **Innovator Spotlight: Kunimasa Sasaki**
Introduction
Kunimasa Sasaki, an accomplished inventor based in Hiroshima, Japan, has made significant contributions to the field of continuous casting technology. With a commendable portfolio of eight patents, Sasaki's work reflects a deep commitment to enhancing the efficiency and reliability of metal casting processes.
Latest Patents
Among his latest innovations are two notable patents. The first is for a **Dual Drum Type Continuous Casting Device and Method for Continuous Casting**. This twin-drum apparatus facilitates the production of metal sheets by supplying molten metal into a pouring basin formed by two cooling drums that rotate in opposing directions. It effectively cools the molten metal through contact with the drum surfaces, subsequently forming a solidified shell. The design incorporates features to mitigate adverse effects arising from thermal expansion differences during casting, thus enhancing the apparatus's reliability and overall casting quality.
His second recent patent pertains to the **Method for Manufacturing a Cooling Drum for a Continuous Casting System**. This cooling drum, designed for continuous casting, boasts a three-layer structure, comprising a rigid member, a cooling member bonded to the rigid member, and a heat-resistance member electro-deposited on the cooling member's surface. The use of austenite stainless steel for the rigid member, combined with copper or copper-alloy for the cooling member, and nickel or cobalt alloys for the heat-resistance member, significantly reduces thermal deformation in the cast pieces, ensuring superior casting outcomes.
