  • Antioxidant agent and process for producing metallic material
    Patent number: 8846152
    Abstract: There is provided an antioxidant agent capable of preventing scale from being produced on the surface of a heated metallic starting material more effectively than the conventional antioxidant agent. The antioxidant agent according to the present invention contains a plurality of glass frits having different softening points and an inorganic compound having a melting point not higher than 600° C. The inorganic compound mainly softens in the low-temperature range of about 600° C. The plurality of glass frits mainly soften in the low-temperature range of about 600 to 1300° C. Therefore, the antioxidant agent covers the surface of metallic starting material in a broad temperature range, oxidizes the surface of metallic starting material, and prevents the production of scale.

  • Upper-end formed glass complex for hot expanding piercing and method of manufacturing billet for hot extrusion pipe making
    Patent number: 8327676
    Abstract: When a hollow billet is inserted into a container, and hot expanding piercing is downwardly performed by using a plug, hot piercing is performed by using a formed glass complex comprising a ring-shaped formed glass part and a ring-shaped projecting part. The ring-shaped formed glass part assumes a disc shape having a circular opening for allowing a plug to be inserted at the center thereof. The ring-shaped projecting part is attached to the opening of the ring-shaped formed glass part, and assumes a ring shape projecting perpendicularly to the ring-shaped formed glass part. Thereby, the piercing work can be done safely, and defects can be prevented from occurring on the inner surface of the billet.
