Method for manufacturing amorphous alloy by using liquid pig iron

1. A method for manufacturing an amorphous alloy, comprising:

tapping liquid pig iron that is provided directly from an iron-making apparatus in its liquid form into a vessel;

adding an alloy material to the liquid pig iron during tapping;

reducing a carbon concentration of the liquid pig iron after the addition of the alloy material; and

solidifying the alloyed liquid pig iron,

wherein the alloy material is at least one material selected from the group consisting of Fe—Si, Fe—P, Fe—B, an oxide, a nitride, and a sulfide and the carbon concentration is reduced by the addition of a material selected from the group consisting of iron oxide, manganese oxide, low carbon scrap, and deoxidized ingot steel.

2. The method of claim 1 , wherein reducing the carbon concentration of the liquid pig iron is performed in a desulfurization process or in any one of a metal mixer, an electric furnace, and a converter.

3. The method of claim 1 , wherein after adding the alloy material and before solidifying the alloyed liquid pig iron the temperature of the liquid pig iron is increased.

4. The method of claim 3 , wherein after increasing the temperature, a composition of the liquid pig iron is controlled.

5. The method of claim 4 , wherein the composition of the liquid pig iron is controlled by adding additional alloy material to the already alloyed liquid pig iron.

6. The method of claim 1 , wherein solidifying of the liquid pig iron includes a powder manufacturing process.

7. The method of claim 1 , wherein solidifying of the liquid pig iron includes a fiber manufacturing process.
