MANUFACTURE OF THIN PLATE OF TITANIUM AND TITANIUM ALLOY

摘要

PURPOSE:To directly stably manufacture the thin plate of Ti and Ti alloy from a molten metal by heating by an electron beam the part where the molten metal inside a water cooling container is brought into contact with the outer circumference of a water cooling roll. CONSTITUTION:The raw material 7 of a Ti or Ti alloy is inputted in a water cooling hearth 8 and melted by the electron beam 10 radiated from an electron gun 9. A molten metal 11 becomes in the flowing out state from the notch part 14 of the water cooling hearth 8 and is made the thin strip 15 of Ti and Ti alloy by being lifted on the outer circumferential face of a rotating water cooling roll 12 and forming a solidified shell continuously. In this case the molten metal of the part approaching to the water cooling roll 12 is always heated by polarizing the electron beam 10 emitted from the electron gun 9 to always remelt the solidifying shell 13 which is going to be formed on the water cooling copper plate of the water cooling copper hearth 8. The Ti and Ti alloy thin plate can thus be stably formed.
