With two patents to his name, Washikita's work focuses on improving quality and yield in the steel manufacturing process through innovative methods and devices.

Latest Patents

Washikita's latest contributions include two key patents that have revolutionized how hot-rolled steel strips are manufactured. The first patent, "Manufacturing device and manufacturing method for hot-rolled steel strip," encompasses a production device designed to achieve the desired material quality by implementing rapid uniform cooling immediately after the rolling process. This device features a finishing rolling mill line, a first cooling unit installed at the exit side of the mill, and a high-precision pinch roll that contacts the strip's upper and lower surfaces. Additionally, a wiping roll is strategically placed between the cooling unit and the pinch roll, complemented by a tension and shape measuring unit to ensure optimal quality.

The second patent, "Method of controlling operation of tandem rolling mill and method of manufacturing hot-rolled steel sheet using the same," provides a novel approach for controlling the operation of tandem rolling mills. This method is instrumental in achieving large reduction rolling necessary for producing fine-grained steel, encompassing steps to accurately determine exit-side sheet thickness during the rolling process, while managing pre-tightening loads effectively.
