- Figure 1 is a schematic diagram showing the change in structure during the wire rod rolling through the simulation of the ball rolling ⁇
- Figure 2 is a photograph of the EBSD organization for Inventive Materials 1 to 5 in the embodiment of the present invention.
- FIG. 3 is a graph showing emu measurement values for Inventive Materials 1 to 5 according to an embodiment of the present invention.
- FIG. 1 is a schematic diagram showing the structure changes during the wire rod rolling through the simulation of the rolling. As can be seen in Figure 1, by using the characteristics of the rolling of the wire in the wire rod unidirectionally by causing the strain (Strain) that can generate a large amount of goth structure affecting the magnetic properties The present invention was completed. Hereinafter, the present invention will be described in detail.
- the C is dissolved in the wire rod and causes lattice distortion and aging during processing, while reducing ductility.
- the C is added at less than 0.03%, there is a problem in that it is not possible to form a uniform goth structure in the wire rod, and when it exceeds 0.05%, the magnetic content is reduced, the carbon content is 0.03-0.05% It is preferable to limit.
- Si is an effective component to improve the iron loss and magnetism by increasing the electrical resistance of the wire, but if less than 33 ⁇ 4, the magnetism is lowered due to the insufficient amount of addition, if it exceeds 5%, the work hardening during the wire rod is rapidly progressed and cannot be rolled Because of the disadvantages ⁇ the content of the silicon is preferably limited to 3.05.0% by weight.
- Manganese (Mn): 0.1-2.0 wt% Mn is a useful component to improve the electrical resistance and improve the iron loss characteristics of the wire rod, but when added to less than 0.1%, Mn can not play a role of compensating the strength when rolling, and when exceeding 2.0%, Mn is processed as There is a problem that causes a hot rolling problem by increasing the curing effect. Therefore, the content of the manganese is preferably limited to 0.1 ⁇ 2.0%.
- A1 it is preferable to limit the content in conjunction with the nitrogen control range because it is an element effective for improving the magnetic properties through the control of nitrogen in the steel.
- A1 is added below 0.02%, it has a disadvantage in that it cannot effectively control nitrogen, and when A1 is added above 0.08%, A1 may precipitate in an atomic state and degrade the magnetism.
- the content is preferably limited to 0.02 to 0.083 ⁇ 4
- N the formation of goth structure is suppressed through lattice deformation and nitride formation with alloying elements due to penetration into the crystal lattice, which causes aging and ductility deterioration.
- Nitrogen is controlled at less than 0.0015% because it is a very harsh process in the steelmaking process and cannot be implemented in the actual process.If it exceeds 0.003%, nitrogen in the steel can move freely, and A1N is increased by increasing the content of A1. In order to make it possible, the content of nitrogen is preferably limited to 0.0015-0.003%.
- the goth structure is less than 2% by area, whereas the wire rod of the present invention includes a Goss structure of 2% or more by area, and thus has a conventional electrical steel sheet or magnetic properties.
- the wire rod has excellent magnetic properties, that is, directivity. More specifically, based on the goth tissue generated at this time, the tissues around the annealing are changed in the direction of the goth tissue to improve magnetic properties. That is, the goth structure acts as an effective directional accelerator, enables movement of magnetic momentum, and magnetization of surrounding tissues during annealing can be easily acted.
- the goth structure is not only magnetic in the rolling direction but also in the rolling right direction. It is an organization that is essential for steel that can display magnetism because it can be expressed.
- the goose tissue is less than 2%, the wire rod cannot be given directivity, and thus the non-directional magnetic property is obtained. That is, the more the goth tissue is generated, the better.
- the upper limit of the goth tissue is limited to 1OT.
- the wire rod has a saturation magnetic flux density of 180 emu or more. When the saturation magnetic flux density is less than 180 emu, it is difficult to impart orientation to the wire rod and may have non-directional magnetic properties.
- the present invention provides not only the wire rod mentioned above, but also a wire rod using the wire rod, and by providing the wire rod freshly, it is possible to impart better magnetic properties to the wire rod.
- the steel wire contains a Goth structure of 7 area% or more, and has a saturation magnetic flux density of 250 emu or more.
- the steel wire also limits the upper limit of goth structure and saturation magnetic flux density to 14 area% and 300 emu, respectively, due to process limitations.
- the wire rod of the present invention has excellent magnetic properties even when manufactured under ordinary conditions of ordinary rolling, as long as it satisfies the composition range, it does not specifically limit the rolling conditions or other manufacturing conditions.
- an example of the manufacturing process of the wire rod for implementing the present invention more preferably As follows.
- heating is performed in ioocKLioo o c for steel materials satisfying the composition range of the present invention. If the heating temperature is less than 1000 ° C in the wire rod process, the steel is extracted from the furnace and the rough rolling causes a surface strain problem due to the severe strain increase, and if it exceeds 1100 ° C, the limit and the surface of the furnace Increasing the scale will reduce the quality of the product. Thereafter, the reheated steel is subjected to ball rolling.
- the process of rolling the wire is an essential process for wire rod rolling, and through the rolling of the wire, the structure of the aggregate structure, that is, the Goss structure, which is involved in magnetic properties is caused by causing a strain by unidirectionally rolling the wire in the wire rod.
- the cold rolling is preferably carried out at 900 ⁇ 1000 ° C. If it is less than 900 ° C, may cause surface defects of the wire rod due to the process load, the fracture of the wire rod may occur. If it is more than 1000 o C, the strain can not be effectively induced due to the increased ductility of the wire during rolling. It is preferable that the reduction ratio of the cross section is 50 to 80% when the rolling is performed. When the reduction ratio of the cross section is less than 50%, it is impossible to distribute the tissue to the magnetic wire because the generation of goth structure is insufficient due to the lack of strain. If it exceeds 80%, the re-stretch force may increase due to severe stretching of the wire rod tissue, and the goth tissue itself may be transformed.
- the wire rod can be further manufactured to produce a steel wire, and the wire rod further improves the magnetic properties of the wire rod.
- the cross-sectional reduction rate is preferably in the range of 10 to 80%. When the cross-sectional reduction rate is less than 10%, there is a drawback that there is no increase in the amount of goth structure because the freshness is not divided. The greater the amount of fresh processing, the better.
- the range of cross-sectional reduction rate is 10 to 80%.
- the range of a more preferable cross section reduction rate is 50 to 80%.
- a more preferred range of cross sectional reduction is 70-80%, where the goth structure accounts for more than 11.5% of the area fraction.
- Comparative Steel 3 0.06 3.0 0.01 0.01 0.007-0.002 Comparative Steel 4 0.06 4.0 0.01 0.01 0.007-0.002 Inventive Steel 1 0.031 3.0 0. 185 0.011 0.007 0.023 0.002 Inventive Steel 2 0.045 3. 1 0.
- FIG. 2 is an EBSD texture photograph of Inventive Materials 1 to 5 of the present invention, and a portion indicated in red in the microstructure photograph represents a goth structure.
- the invention materials 1 to 5 which is a wire rod that satisfies the composition range of the present invention is formed of a goth structure up to 2.0 ⁇ 6.73 ⁇ 4.
- the fraction of goth tissue after hot rolling is less than about 2%, while Inventive Materials 1 to 5 are invented by Goose, which exhibits the worst characteristics.
- the wire rod of the present invention has superior magnetic properties than the conventional oriented steel sheet because it contains a goth structure.
- the saturation magnetic flux densities of the inventive materials 1 to 5 are 181 to 255 emu and have excellent saturation magnetic flux densities of 180 emu or more and exhibit excellent magnetic properties.
- 3 is a graph showing the result of the saturation magnetic flux density, which is measured using VSM (Vibration Sample Measurement).
- Inventive Material 3 has the best saturation magnetic flux density, which is because it has the optimum carbon and silicon content, suppresses the solid solution or aging of the crystal lattice, and This is because it inhibits nitrogen, thereby maximizing lattice stability and activating goth tissue.
- the steel wires manufactured through the drawing process increased the Goth tissue fraction by a certain level or more as compared with the wire rod.
- the invention materials 1 to 5 in accordance with the conditions of the present invention is a Goth tissue fraction of 9.9 area% or more and It was found to have a saturation flux density of more than 271 emu.
- the steel wires of the present invention has excellent magnetic properties.
- the comparative materials 1 to 4 it can be seen that the goose structure fraction increase is relatively small because it does not satisfy the steel composition of the present invention, the comparative materials 5 to 8 noticeably increase the goth structure fraction because it satisfies the steel composition It can be seen that.
