Title: Innovations of Yoshitada Hanai
Introduction
Yoshitada Hanai is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of wire production, holding three patents that showcase his innovative processes. His work primarily focuses on the production of hot dipped wires, which are essential in various industrial applications.
Latest Patents
Hanai's latest patents include a process of producing a hot dipped wire from a base wire. In this process, the base wire is passed over a passage surface made of a non-iron material during wire drawing. After undergoing steam heating, cleaning, and drying steps, the wire is heated in a reducing gas atmosphere. This effectively removes the oxide layer on the wire's surface and preheats the wire to accelerate the reaction with molten hot dipping metal in the subsequent hot dipping step. Another patent involves a similar process, where a water-soluble lubricant is used during wire drawing. The drawn wire is heated in a reducing gas atmosphere to remove organic residues and oxides, while also annealing and preheating the wire for the hot dipping process.
