With a total of 4 patents to his name, Yamagishi's work has had a considerable impact on manufacturing processes.
Latest Patents
One of Yamagishi's latest patents is a method for continuously quenching electrolytic tin-plated steel strips. This innovative technique aims to enhance the surface quality of tin-plated layers on steel strips. The process involves heating the strip in a traditional continuous heating furnace to achieve rapid fusion of the tin-plated layer, followed by a two-stage quenching process. The initial stage employs a relatively low-rate quenching by spraying a quenching liquid mist onto both sides of the strip. This is done before the strip enters the quenching tank, ensuring uniform cooling. The second stage involves a high-rate quenching, where a high-pressure quenching liquid is sprayed onto the strip after it has entered the quenching tank. This method not only improves corrosion resistance but also prevents the occurrence of quench stains.
