Title: Kazutoshi Ishikawa: Innovator in Steel Pipe Technology
Introduction
Kazutoshi Ishikawa is a prominent inventor based in Aichi, Japan. He has made significant contributions to the field of steel pipe technology, holding a total of 3 patents. His work focuses on enhancing the manufacturing processes and properties of steel pipes, particularly for applications in stabilizers.
Latest Patents
One of Ishikawa's latest patents is for an electric-resistance-welded steel pipe or tube designed for a hollow stabilizer. This innovation addresses the challenge of suppressing the formation of both ferrite decarburized layers and total decarburization layers during heat treatment in air. The patented steel pipe features a specific chemical composition, ensuring that the depths of total decarburized layers on both the inner and outer surfaces remain at 100 μm or less.
Another notable patent involves a tube expanding method for manufacturing metal tubes. This method utilizes a tube expanding processing simulation to evaluate the workpiece shape after it has advanced through a tool's shoulder portion. The innovation ensures that the external diameter remains within ±1% of the target, the thickness within ±7.5% of the target, and the internal gap between the hollow piece and the tool is maintained at 1.0 mm or less. This meticulous approach allows for the determination of actual tube expanding manufacturing conditions.
