Title: Nobuo Tanaka: Innovator in Steel Processing Technologies
Introduction
Nobuo Tanaka is a prominent inventor based in Fukuyama, Japan. He has made significant contributions to the field of steel processing, particularly through his innovative methods in continuous annealing. With a total of 2 patents to his name, Tanaka's work has had a substantial impact on the manufacturing of cold-reduced steel strips.
Latest Patents
Tanaka's latest patents include a "Continuous annealing method for cold reduced steel strip" and a "Method of making a soft steel sheet by continuous annealing." The first patent describes a continuous annealing process that incorporates a rapid cooling stage and a carbon precipitation treating stage. This method allows for a rapid cooling rate achieved by initially heating the steel above the recrystallization temperature and then slowly cooling it to maintain a temperature above 200°C per second. The starting temperature is carefully controlled between 500°C and just below 600°C, resulting in improved press-formability of the continuously annealed steel strip. The second patent outlines a process for producing a cold-reduced steel strip suitable for press-forming, which involves a rapid cooling step after recrystallization heating and an over-aging treatment step. This method enables the production of a cold-reduced soft steel sheet without the need for cooling water sprays during the hot-rolling stage.
