Title: Kiyoshi Morii: Innovator in Heat Resistant Technologies
Introduction
Kiyoshi Morii is a notable inventor based in Konan, Japan. He has made significant contributions to the field of heat-resistant materials, holding a total of 4 patents. His work focuses on developing innovative solutions that enhance the performance and durability of materials used in high-temperature environments.
Latest Patents
Morii's latest patents include a multi-layered anti-coking heat resisting metal tube and a method for manufacturing it. This innovative tube exhibits excellent anti-coking characteristics, making it suitable for conditions where carbon deposits tend to accumulate due to contact with hydrocarbons at high temperatures. The tube is constructed by forming a weld-mounted overlaid layer of a Cr–Ni–Mo alloy on the inner and/or outer surface of a substrate tube made from heat-resistant metal. The alloy composition consists of 36-49 wt % Cr, 35-63 wt % Ni, and 0.5-5 wt % Mo. The manufacturing process utilizes Plasma Powder Welding (PPW), where the filler metal is supplied in powder form.
Another significant patent involves a vertical continuous casting method and apparatus. This invention includes drawing a strand formed in a water-cooled mold vertically downward and positioning light reduction pinch rollers just before the solidification completion point. This technique applies a light reduction force to the strand, compensating for contraction during solidification, thereby preventing central cavities and reducing central segregation.
