Title: Shigefumi Matsumoto: Innovator in Refractory Materials
Introduction
Shigefumi Matsumoto is a notable inventor based in Fukuoka, Japan. He has made significant contributions to the field of refractory materials, holding 2 patents that showcase his innovative approach to enhancing material properties.
Latest Patents
Matsumoto's latest patents include a CaO—ZrO composition and a method for producing this composition. His work on a CaO—ZrO-containing refractory material and casting nozzle has led to the development of a ZrO—CaO—C based refractory material. This material is designed to maintain high adhesion resistance over extended periods while exhibiting significant slaking resistance and suppressing self-fluxing, thereby demonstrating corrosion-erosion resistance. The refractory material comprises a CaO—ZrO composition containing a CaO component in an amount of 40% by mass to 60% by mass. The mass ratio of the CaO component to the ZrO component is maintained between 0.67 to 1.5. Additionally, the CaO—ZrO composition includes a eutectic microstructure of CaO crystals and CaZrO crystals, with each CaO crystal observable in a cross-sectional microstructure measuring 50 μm or less. Furthermore, he has developed a refractory product that is not impregnated with pitch or similar substances, which offers higher corrosion-erosion resistance and thermal shock resistance compared to traditional products.
Career Highlights
Matsumoto is currently associated with Krosakiharima Corporation, where he continues to innovate in the field of refractory materials. His work has significantly impacted the industry, providing solutions that enhance the durability and performance of refractory products.
