Example Embodiment
[0035] According to a preferred embodiment of the present invention, the aluminum skin is made of 1050A aluminum (Al content is 98.5% by weight, and the balance is Si <0.25 wt%, Fe <0.45 wt% etc.) made.
[0036] According to the cored wire of the present invention, the thickness of the aluminum skin is preferably 0.8-1.5 mm. The aforementioned cored wire is used for titanium alloying of molten steel, the recovery rate of titanium is high and stable, and the titanium alloy steel obtained after casting of the obtained titanium alloyed molten steel has high yield strength and tensile strength.
[0037] According to the cored wire of the present invention, the diameter of the cored wire is preferably 12-20 mm. The aforementioned cored wire is used for titanium alloying of molten steel, the recovery rate of titanium is high and stable, and the titanium alloy steel obtained after casting of the obtained titanium alloyed molten steel has high yield strength and tensile strength.
