METHOD FOR MANUFACTURING TITANIUM INGOT |
摘要 |
<p>The present invention is a method for manufacturing a titanium ingot (30), the method being characterized by comprising: a step of melting a titanium alloy for a predetermined time by cold crucible induction melting (CCIM); a step of supplying molten titanium (6) to a cold hearth (10), and separating high density inclusions (HDIs) (8) by precipitation in the cold hearth (10) while spraying a plasma jet or an electron beam onto the bath surface of the molten titanium (6); and a step of supplying a molten titanium starting material from which the HDIs (8) are separated by precipitation to a mold (20) to obtain the titanium ingot.</p> |
