Description
すなわち本発明は、質量％でＣａＯ≦１５％、１％≦ＴｉＯ２≦１５％、５％≦Ａｌ２Ｏ３≦３０％、残部ＣａＦ２のスラグを用いて、質量％で０．５％≦Ｔｉ≦５．０％、０．１％≦Ａｌ≦２．０％を含む合金材を不活性ガス雰囲気中でエレクトロスラグ再溶解するインゴットの製造方法である。
本発明のインゴットの製造方法は、前記スラグに、Ａｌを３質量％以下、および／またはＬｉＦを１５質量％以下添加することが好ましい。
また、本発明のインゴットの製造方法は、前記スラグが、式（１）を満たすことがより好ましい。
式（１） ３．２≦０．８１ｌｏｇ｛［％Ｔｉ］３／［％Ａｌ］４｝−ｌｏｇ［（Ｎ ＴｉＯ２ ）３／（ＮＡｌ２Ｏ３）２］≦４．５
但し、［％］＝合金中のＴｉ、Ａｌ質量％、（Ｎ）＝スラグ中のＴｉ、Ａｌのモル分率
That is, the present invention uses slag of CaO ≦ 15%, 1% ≦ TiO 2 ≦ 15%, 5% ≦ Al 2 O 3 ≦ 30%, and the balance CaF 2 in mass%, and 0.5% ≦ mass%. This is an ingot manufacturing method in which an alloy material containing Ti ≦ 5.0% and 0.1% ≦ Al ≦ 2.0% is re-dissolved by electroslag in an inert gas atmosphere.
In the method for producing an ingot according to the present invention, it is preferable to add 3% by mass or less of Al and / or 15% by mass or less of LiF to the slag.
Moreover, as for the manufacturing method of the ingot of this invention, it is more preferable that the said slag satisfy | fills Formula (1).
Formula (1) 3.2 ≦ 0.81 log {[% Ti] 3 / [% Al] 4 } −log [(N TiO 2 ) 3 / (N Al 2 O 3 ) 2 ] ≦ 4.5
However, [%] = Ti and Al mass% in the alloy, (N) = Mole fraction of Ti and Al in the slag.
