Title: The Innovative Contributions of Keisuke Fujisaki
Introduction
Keisuke Fujisaki, a prominent inventor based in Futtsu, Japan, has made significant contributions in the field of metallurgy with a total of six patents to his name. His inventive spirit and engineering prowess are evident in his latest groundbreaking inventions that enhance the efficiency and safety of steel processing.
Latest Patents
One of Fujisaki’s latest inventions is the electromagnetic stirrer coil. This innovative device is designed for stirring molten steel in a mold using electromagnetic force. It is characterized by a compact design with a high thrust capability, where the space factor of the yoke sectional area relative to the inside area in a vertical cross-section is between 0.5 and 0.9. The yoke width ranges from 100 mm to 300 mm, and it is noted that the magnetomotive force divided by the yoke width should be 800 kAT/m or more to achieve optimal performance.
Another significant patent by Fujisaki is a flaw detection device specifically designed for high-temperature steel bars. This device facilitates the inspection of steel bars at elevated temperatures by employing a pre-treatment unit, detection unit, and post-treatment unit aligned with the running direction of the steel bar. The device uses direct current coils to magnetically saturate the steel bar while an alternating current coil generates eddy currents at its surface. The change in the magnetic field induced by these eddy currents is then detected, ensuring that noise due to magnetic field changes is minimized as the steel bar moves at high speed.
