Title: Kazuo Okamura: Innovator in Steel Pipe Cooling Technologies
Introduction
Kazuo Okamura is a prominent inventor based in Nishinomiya, Japan. He has made significant contributions to the field of metallurgy, particularly in the cooling methods for steel pipes. With a total of 7 patents to his name, Okamura's work has had a substantial impact on the industry.
Latest Patents
Okamura's latest patents include innovative methods for cooling steel pipes. One notable patent is the continuous casting method and apparatus, which focuses on cooling a martensitic steel pipe. This method involves cooling both the inner and outer surfaces of the pipe equally while it rotates around its axis, achieving a cooling rate of 8°C/s or higher. Additionally, the inner surface is cooled by passing water without completely filling the inside of the pipe. The maximum cooling rate for both surfaces is capped at 35°C/s for martensitic stainless steel pipes. Another significant patent details a 2-step cooling method, which includes air cooling from 30°C below the martensitic transformation start temperature to the average of the start and finish temperatures, followed by intensive water cooling below the finish temperature. Furthermore, a 3-step cooling method is described, which involves intensive cooling from 400°C above the start temperature down to the start temperature, followed by mild cooling and further intensive cooling to the finish temperature.
