Title: Innovations by Hideki Tonaka

Introduction

Hideki Tonaka is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of rolling mill technology. With a total of 2 patents, his work focuses on improving the efficiency and accuracy of rolling processes.

Latest Patents

One of his latest patents is related to a rolling mill and rolling mill adjustment method. This invention includes a work-side position measurement device and a drive-side position measurement device for directly measuring the positions of roll chocks in a rolling direction. The positions of upper and lower working rolls, as well as upper and lower backup rolls, are adjusted to a zero point or predetermined positions. Additionally, the invention calculates changes caused in the strip wedge due to minute crossings of the axes of working rolls and backup rolls. This allows for the adjustment of the quantities of leveling of both work-side and drive-side rolling reduction cylinder devices, ensuring that the strip edge remains equal to or smaller than a predetermined value. Consequently, the bilateral asymmetry of the thickness distribution of a rolled material can be easily adjusted, even when the positions of the roll chocks change due to wear on various components.
