摘要： A continuous casting method in which a molten metal obtained by melting titanium or a titanium alloy is injected into a bottomless mold having a rectangular cross-section and withdrawn downward while being caused to solidify, wherein a plasma torch (7) is caused to rotate in the horizontal direction above the surface of the molten metal (12) in the mold (2), and a horizontally rotating flow is generated by electromagnetic stirring on at least the surface of the molten metal (12) in the mold (2). It is thereby possible to cast a slab in which the casting surface condition is excellent.

摘要： The objective of the present invention is to improve non-defective product yield by reducing shrinkage cavities inside small-diameter ingots, in a method for casting active metals. In this Ti-Al based alloy casting method for casting an ingot of Ti-Al based alloy by tapping molten metal from a tapping hole (5) provided in a bottom portion of a water-cooled copper crucible (2), in an induction melting furnace (3) employing said crucible (2), into a casting mold (4), the degree of vacuum inside the induction melting furnace (3) when the Ti-Al based alloy is being melted or cast is in a range of 80 to 700 Torr, and the Al concentration in the cast ingot is within ±1.0 mass% of a target value.

摘要： This method for purifying a titanium material is a deoxidization method for removing oxygen contained in a titanium material from the titanium material that is formed from pure titanium, a titanium alloy or an intermetallic compound that contains titanium as one of the main components. This method for purifying a titanium material comprises: a first melting step wherein hydrogen is introduced into the titanium material in a molten state by melting the titanium material in a rare gas atmosphere containing 5-70% by volume of hydrogen; and a second melting step wherein oxygen contained in the titanium material is removed together with hydrogen from the titanium material in a molten state by melting the titanium material, into which hydrogen has been introduced during the first melting step, in a rare gas atmosphere. The first melting step and the second melting step are carried out one or more times, respectively.
