Title: Innovations and Contributions of Atsushi Ishii in Rolling Mill Technology

Introduction

Atsushi Ishii is a prominent inventor based in Tokyo, Japan, known for his significant contributions to the field of rolling mill technology. With a remarkable portfolio of 60 patents, Ishii has demonstrated an exceptional ability to innovate and improve industrial processes. His inventions focus on enhancing the efficiency and effectiveness of rolling mills, which are critical in metal processing industries.

Latest Patents

One of Ishii's latest patents involves a sophisticated rolling mill and method for setting a rolling mill. This invention introduces a four-high or more rolling mill equipped with measurement apparatuses that utilize one roll as a reference roll. It measures the rolling direction forces acting on the roll chocks on both the work side and the drive side of each roll, excluding the backup roll. The invention also includes pressing apparatuses to apply pressure to the roll chocks in the rolling direction, driving apparatuses that facilitate the movement of the roll chocks, and a position control unit that determines the rolling direction position of the roll chocks based on the rolling direction force difference. This ensures that the force differences remain within an allowable range.

Ishii has also developed a zigzagging control method for workpieces. This method encompasses an estimation step that acquires inter-roll thrust forces and material-roll thrust forces prior to the rolling of the tail portion of a workpiece. During the rolling process, this invention measures rolling loads and corrects any differences in rolling loads to perform reduction leveling control on the rolling mill.
