Definitions
- the present invention relates to a steel wire, a steel wire, and a method for producing them. More specifically, for example, rolled wire rods suitable for applications such as radial tires for automobiles, steel cords used as reinforcing materials for various industrial belts and hoses, sawing wires, and the manufacturing method thereof, and The present invention relates to a steel wire made of rolled wire. Background art
- Steel wire for steel cords used as a reinforcing material for radial tires of automobiles, various belts and hoses, or steel wire for sawing wires generally has a wire diameter (diameter) of 4 adjusted and cooled after hot rolling.
- a steel wire of ⁇ 6 mm is subjected to primary wire drawing to a diameter of 3 to 4 mm, then subjected to intermediate patenting treatment, and further subjected to secondary wire drawing to a diameter of 1 to 2 mm. After this, a final patenting process is performed, followed by a blaze treatment, and a final wet wire drawing to a diameter of 0.15 to 0.40 mm.
- Steel cords are manufactured by twisting together the ultrafine steel wires obtained in this way into a twisted steel wire by twisting processing.
- the drawing value which is one of the indexes indicating the ductility of the patenting wire, depends on the austenite grain size. Since the drawing value is improved by reducing the austenite grain size, Nb, Ti, B Attempts have also been made to refine the austenite grain size by using carbides and nitrides such as these as pinning particles.
- Japanese Patent No. 2609387 includes Nb: 0.01 to 0.1% by weight, Zr: 0.05 to 0.1% by weight, Mo: 0.02 to 0.5% by weight as component elements.
- a technique for further enhancing the toughness of ultrafine steel wire by containing at least one kind from the group is disclosed.
- Japanese Laid-Open Patent Publication No. 2001-13 1697 also proposes miniaturization of austenite grain size by NbC.
- Nb forming coarse carbides and nitrides
- Ti forming coarse oxides, for example, a thin wire diameter, for example, a diameter of 0.40 D1DI. If the wire was drawn to the following wire diameter, it could break. Further, according to the verification by the present inventors, it is difficult to make the austenite grain size fine enough to affect the aperture value in BN pinning.
- the present invention has been made in view of the above-described situation, and its purpose is to produce a high-strength wire rod excellent in yieldability suitable for applications such as steel cords and sawing wires with high yield and low cost. Is to provide The
- the area ratio of the parlite structure is 97% or more, the balance is bainite, pseudo-parrite, and non-parrite structure consisting of proeutectoid ferrite, and the particle block particle size is 20 ⁇ m or more 45 ⁇
- the patenting process is performed by a cooling method in which the cooling speed from 800 to 600 ° C is 5 ° CZ s or more. (1) thru
- Figure 1 shows the relationship between the non-partite area ratio and the average true strain that breaks due to wire drawing.
- Figure 2 shows the relationship between TS and average true strain that breaks due to wire drawing.
- Fig. 3 is a graph showing the relationship between particle block particle size and average true strain fractured by wire drawing.
- the present inventors have repeatedly investigated and studied the influence of the chemical composition and mechanical properties of the wire on the wire drawing workability, and as a result, have obtained the following knowledge.
- the drawing workability shows a good correlation between the tensile strength before drawing, that is, after heat treatment, and the drawing value at break, and extremely good drawing when the drawing value is a certain value or more according to the tensile strength. Line workability is obtained.
- (c) B forms a compound with N, and the solid solution B amount is determined by the total B amount, N amount and the heating temperature before the perlite transformation.
- Solid solution B segregates at the austenite grain boundaries, and during cooling from the austenite temperature during the patenting process, microstructures such as bait, ferrite and pseudo-parite generated from the austenite grain boundaries Is rough and low Suppresses the generation of strong tissues, especially bait.
- the bainite the one that has the most negative effect on wire drawing is the bain
- Bainite accounts for over 60% of non-partite organizations. If the amount of solute B is small, the above effect is small, and if it is excessive, coarse Fe 23 (CB) 6 precipitates before the perlite transformation, and the wire drawing process is lowered.
- the present invention has been completed based on the above findings.
- the rawness of the patented wire is correlated with the amount of non-partite structure such as proeutectoid ferrite, pseudo-parrite, and bainite. If the volume ratio can be suppressed to less than 3%, the occurrence of early cracks during wire drawing can be suppressed, and the stretchability can be improved.
- B is added and the coiling temperature after hot rolling is taken up in the temperature range above the temperature Tmin shown below, and then the cooling speed from 800 to 600 ° C is increased. We have found that it is effective to perform the patenting process with a cooling method of 5 ° C / s or more.
- T min 800 ° C
- Tmin 950 + 1450 / (B (ppm)-0.77XN (ppm)-10) This makes it possible to obtain a high strength wire rod with a non-partite volume fraction of less than 3% and excellent in the stretchability.
- the particle size of the pearlite block depends on the austenite ⁇ ⁇ particle size and the pearlite transformation temperature (cooling speed in the case of continuous cooling). The effect of transformation temperature is large. Therefore, the coarse block size means that the transformation temperature is high. Means small). If the coarse grain of the austenite is coarsened, even if B is added, a coarse non-partite structure is formed, resulting in deterioration of the rawness.
- the winding temperature is desirably 950 ° C or less from the viewpoint of descaling.
- C is an element effective for increasing the strength of the wire, and if its content is less than 0.70%, it is difficult to stably impart a high strength of 2800 MPa or more to the final product. At the same time, precipitation of proeutectoid ferrite is promoted at the grain boundaries, making it difficult to obtain a uniform pearlite structure.
- the C content is too high, not only does a net-like pro-eutectoid cementite form at the austenite grain boundaries and breakage occurs during wire drawing, but the toughness of the ultrafine wire after the final wire drawing will increase. • Significantly deteriorates ductility. Therefore, the content of C is set to 0.70 to 1.10% by mass.
- S i is an element effective for increasing the strength. Furthermore, it is an element useful as a deoxidizer, and is also an element necessary when targeting steel wires that do not contain A1. Less than 1% by mass, the deoxidation action is too small. On the other hand, if the amount of Si is too large, precipitation of pro-eutectoid ferrite will be promoted even in hypereutectoid steel, and the limit workability in wire drawing will be reduced. In addition, the wire drawing process by mechanical dual force descaling (hereinafter abbreviated as MD) is difficult. become. Therefore, the Si content is set to 0.1 to 1.5 mass%.
- MD mechanical dual force descaling
- ⁇ is an element useful as a deoxidizer. It is also effective in improving hardenability and increasing the strength of the wire. Furthermore, Mn has the effect of preventing hot brittleness by fixing S in steel as MnS. If the content is less than 0.1% by mass, it is difficult to obtain the above effect. On the other hand, Mn is a segregating shading element. If it exceeds 1.0 mass%, it will be prayed especially at the center of the wire, and martensite and baininess will be generated in the segregated part. descend. Therefore, the Mn content is set to 0.1 to 1.0% by mass.
- A1 0.01% or less: The content of A1 is defined as 0.01% or less, including 0%, so that hard non-deformation alumina-based non-metallic inclusions are not generated to cause ductility deterioration and wire drawing deterioration of the steel wire. .
- Ti 0.01% or less: Ti content is specified to be 0.01% or less, including 0%, so that hard non-deformable oxides are not formed and the steel wire is not ductile and drawn.
- N 10-60ppm: N produces B and nitrides in steel and has the effect of preventing coarsening of austenite and grain size during heating. The effect is effectively demonstrated by containing lOppm or more. The However, if the content is too high, the amount of nitride increases too much, and the amount of solute B in the austenite decreases. Furthermore, there is a risk that solute N will promote aging during wire drawing, so the upper limit is 60 ppm.
- B 5 or (0.77XN (ppm)-17.4) to 50ppm:
- B When B is present in the austenite in the solid solution state, it concentrates at the grain boundary and is not ferritic, pseudo-palite, paynite, etc. Inhibits the formation of pearlite soot precipitation.
- coarse Fe is added in the austenite.
- Impurities P and S are not specified, but each is preferably 0.02% or less from the viewpoint of securing ductility as with conventional ultrafine steel wires.
- the steel wire used in the present invention has the above-mentioned elements as basic components, but for the purpose of further improving mechanical properties such as strength, toughness and ductility, one type of selectively permissible additive elements as follows is used. Or, two or more kinds may be actively included.
- Cr 0.03 to 0.5% Cr is an element effective in refining the lamellar spacing of particles and improving the strength of the wire and the wire drawing workability. Addition of 0.03% or more is preferable for effectively exhibiting such an effect. On the other hand, if the amount of Cr is too large, the transformation end time becomes longer, and there is a risk of forming a supercooled structure such as martensite and bainite in the hot rolled wire rod. The upper limit was 0.5%.
- Ni 0.5% or less Ni does not contribute much to the strength of the wire, but is an element that increases the toughness of the wire. Addition of 0.1% or more is preferable in order to exert such an effect effectively. On the other hand, if Ni is added excessively, the transformation end time becomes longer, so the upper limit was set to 0.5%.
- Co 1% or less Co is an element effective in suppressing precipitation of proeutectoid cementite in the rolled material. Addition of 0.1% or more is preferable for effectively exhibiting such an effect. On the other hand, if Co is added excessively, the effect is saturated and economically useless, so the upper limit is set at 0.5%. 07058889.
- V 0.03-0.5%
- V forms fine carbonitrides in the ferrite to prevent coarsening of austenite grains during heating, improve ductility, and increase strength after rolling. Contribute. Addition of 0.03% or more is preferable in order to exert such an action effectively. However, if the amount is excessively added, the amount of carbonitride formed becomes too large and the particle size of the carbonitride increases, so the upper limit was made 0.5%.
- Cu 0.2% or less Cu has the effect of enhancing the corrosion resistance of ultra fine steel wires. Addition of 0.1% or more is preferable for effectively exhibiting such an effect. However, if it is added in excess, it reacts with S and segregates CuS in the grain boundaries, so that ingots are generated in the steel ingot and wire during the wire manufacturing process. In order to prevent such adverse effects, the upper limit was set to 0.2%.
- Mo has the effect of enhancing the corrosion resistance of ultra fine steel wires. Addition of 0.1% or more is preferable for effectively exhibiting such an effect. On the other hand, if Mo is added excessively, the transformation completion time becomes longer, so the upper limit was set to 0.2%.
- W has the effect of increasing the corrosion resistance of ultra fine steel wires. Addition of 0.1% or more is preferable for effectively exhibiting such an effect. On the other hand, if W is added excessively, the transformation end time becomes longer, so the upper limit was set to 0.2%.
- Nb has the effect of increasing the corrosion resistance of ultra fine steel wires. Addition of 0.05% or more is preferable in order to exert such an effect effectively. On the other hand, when Nb is added excessively, the transformation completion time becomes longer, so the upper limit was set to 0.1%.
