Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for manufacturing a titanium alloy ingot (the titanium alloy being allowable to be pure titanium), comprising: (a) melting a titanium material or titanium scrap material (hereinafter referred to as “titanium material”) by a cold crucible induction melting (hereinafter referred to as “CCIM”) in such a manner that the following expression (1) can be satisfied: y≧ 700 ×A −1.2 (1) wherein A=P/(V/S) wherein y: the period [min] for t…
