Definitions
- the present invention relates to a method for producing an amorphous alloy, and more particularly, to a method for producing a large amount of amorphous alloy using molten iron.
- an alloying material containing a desired component In general, to make an amorphous alloy, an alloying material containing a desired component must be added. However, existing processes are suitable for producing small quantities of products, but not for mass production.
- the present invention is to provide a method for producing a large amount of amorphous alloy using the molten iron.
- the method of manufacturing an amorphous alloy according to an embodiment of the present invention may include providing a molten iron, injecting an alloying material into the molten iron, and solidifying the molten iron.
- the step of injecting the alloying material and the step of solidifying the molten iron may further comprise the step of adjusting the carbon concentration of the molten iron.
- the step of adjusting the carbon concentration of the molten iron may be made in any one of a crossroad furnace, an electric furnace, a converter and a desulfurization process.
- gas or solid oxide may be blown into the molten iron.
- the gas may be at least one gas selected from the group consisting of pure oxygen, synthetic oxygen, and air, and the solid oxide may include iron oxide or manganese oxide.
- step of adjusting the carbon concentration of the molten iron may be added to the molten iron low carbon scrap or deoxidized molten steel.
- the step of injecting the alloying material and the step of solidifying the molten iron may further comprise the step of increasing the temperature of the molten iron.
- the step of increasing the temperature may further comprise the step of adjusting the composition of the molten iron.
- the step of adjusting the composition of the molten iron may be added to the alloying material to the molten iron.
- the alloying material may be introduced while the molten iron is drawn out in the step of injecting the alloying material, and the alloying material may be added while being included in ferroalloy or scrap.
- the alloy material may be at least one material selected from the group consisting of Fe-Si, Fe-P and Fe-B.
- the alloy material may be one or more materials selected from the group consisting of oxides, nitrides and sulfides.
- the step of solidifying the molten iron may include a powdering process or a fiber manufacturing process.
- a large amount of amorphous alloy can be produced using molten iron.
- FIG. 1 is a view showing a method of manufacturing an amorphous alloy according to an embodiment of the present invention.
- FIG. 1 is a view showing a method of manufacturing an amorphous alloy according to an embodiment of the present invention.
- a method of manufacturing an amorphous alloy includes providing molten iron (S100), injecting an alloying material into molten iron (S120), and solidifying molten iron (S140).
- step S100 the molten iron is produced by the Finex process or the molten iron is manufactured by a molten iron manufacturing process such as a blast furnace.
- step S120 while the molten iron is received in a container such as a Torpedo car or a ladle, an alloy material (Fe-Si, Fe-P, Fe-B, etc.) corresponding to the component system of the amorphous alloy is required. ) Or scrap is added to the molten iron, and the alloying element is added.
- an alloying element can be added by injecting oxide, nitride, or sulfide containing an alloying element.
- the molten iron is suitable for injecting silicon (Si), boron (B) or phosphorus (P), which are alloying elements having a lower oxidation tendency than carbon, because the melting temperature is about 1150 ° C and carbon (C) is saturated in the molten iron. That is, silicon (Si), boron (B) or phosphorus (P) can be easily added to the molten iron in the atmosphere under minimal oxygen partial pressure atmosphere formed by saturated carbon while minimizing oxidation loss.
- the reduction efficiency is maximized due to the drop agitation force and the sensible heat of the molten iron generated in the process of the molten iron falling into the container. Oxidation heat generated at this time promotes the alloying reaction of the molten iron and raises the temperature of the molten iron.
- step S140 the molten iron is solidified to prepare an amorphous alloy.
- the molten iron which has reached the target composition is solidified through a powdering step or a fiber manufacturing step to finally form an amorphous alloy.
- the method may further include adjusting the carbon concentration of the molten iron between step S120 and step S140 (S160).
- step S160 the carbon concentration of the molten iron is adjusted by blowing a gas or a solid oxide into the molten iron.
- Step S160 may be performed in any one of a crossroad furnace, an electric furnace, a converter, and a desulfurization process.
- step (S160) is made in the crossroads
- the molten iron is put in a topedo car or ladle and then charged to the crossroads.
- Gas or solid oxide is blown through the nozzle, which may be attached to the bottom or side of the crossroads.
- the gas or solid oxide may be blown through the nozzle descending from the top of the cross-section.
- gas or solid oxide may be blown through a nozzle mounted on the desulfurization stirrer.
- step S160 When step S160 is performed in an electric furnace (or converter), gas or solid oxide may be blown through a nozzle attached to the bottom or side of the electric furnace (or converter). On the other hand, gas or solid oxide may be blown through the nozzle descending from the top of the electric furnace (or converter).
- the gas may include pure oxygen, mixed oxygen or air, and the solid oxide may include iron oxide or manganese oxide.
- the method may further include adjusting the composition of the molten iron (S180).
- step S180 the target composition of the molten iron is achieved. If necessary, the target composition can be achieved by increasing the temperature of the molten iron and then injecting an alloying material. In step S180, the same alloy material used in step S100 may be used. If the step (S180) is made in the crosstalk, shaking the crosstalk can make the alloying material well dissolved and the alloying efficiency can be increased. By appropriately controlling the composition of the alloying element in step (S180) it is possible to produce a high quality amorphous alloy without a subsequent steelmaking process.
