Joule hot metal rolling apparatus

摘要

Problem to be solved: to provide a Joule hot metal rolling apparatus suitable for rolling of a tungsten alloy with a transition metal carbide having a high toughness and a high heat resistance while rolling the pressure applying portion of the metal material locally while heating it locally.Solution: a container filled with vacuum or inert gas containing metal material, and an upper conductive roll and a lower conductive roll for pressing the local area of the metal material in the vacuum vessel up and down and Joule heating by applying electric current to the local area, and the metal material is Joule hot metal rolling apparatus characterized by rolling by grain boundary sliding deformation was constructed.Diagram
