Title: Hiroshi Mihashi and His Patent for Casting an Amorphous Refractory Lining.

Introduction

Hiroshi Mihashi is an inventor associated with Fukuyama, Japan, and Nippon Kokan Kabushiki Kaisha. His recorded patent concerns a method and apparatus for applying an amorphous refractory lining to the inside of a molten-metal vessel.

Latest Patents

Mihashi’s listed patent is “Method and Apparatus for Casting an Inner Lining Amorphous Refractory.” The invention addresses how to distribute refractory material when a lining frame is placed inside a vessel that already has a permanent refractory lining. The amorphous refractory is cast into the space between the permanent lining and the frame.

The disclosed apparatus uses a conical distributor positioned above the lining frame. A rotary chute continuously delivers refractory material onto the distributor, creating a concentric path of moving falling points. This arrangement is intended to distribute the material across the space being lined. Mihashi is credited with 1 patent.
