The properties of carbon steel are high hardness, power, put on resistance and anti-corrosion. A wire rod mill is normally a single-strand or two-strand facility consisting of a roughing prepare, intermediate continuous prepare, finishing train and cooling traces, as well as bundling, dealing with and ending end. Carbon metal rods are produced in numerous grades or compositions: low-carbon, medium-low-carbon, medium-high-carbon, and excessive-carbon steel wire rods. However, before 2000, only a few steelworks in China could produce excessive-carbon metal like 82B (SWRH82B, zero.79-0.86 wt.% C, zero.15-0.35 wt.% Si, 0.3-zero.6 wt.% Mn, ≤zero.03 wt.% P, ≤0.03 wt.% S) for metal strands by bloom casting and subsequent two-stage hot rolling (steady casting-sizzling rolling-hot rolling-high-velocity wire rolling); nearly no steelworks can produce tire cord metal and noticed wire steel. Grade 1080 tire cord quality rod is outlined as: (i) grade 1080 tire twine quality wire rod measuring 5.0 mm or more but not more than 6.zero mm in cross-sectional diameter; (ii) with an average partial decarburization of not more than 70 microns in depth (most individual 200 microns); (iii) having no non-deformable inclusions higher than 20 microns and no deformable inclusions greater than 35 microns; (iv) having a carbon segregation per warmth common of three.zero or better utilizing European Methodology NFA 04-114; (v) having a surface quality with no surface defects of a length better than 0.15 mm; (vi) able to being drawn to a diameter of zero.30 mm or much less with 3 or fewer breaks per ton, and (vii) containing by weight the next parts within the proportions proven: (1) zero.78 p.c or more of carbon, (2) lower than zero.01 percent of aluminum, (three) zero.040 p.c or less, in the aggregate, of phosphorus and sulfur, (four) zero.006 percent or much less of nitrogen, and (5) not more than zero.15 p.c, within the mixture, of copper, nickel and chromium. 2) Chilly-drawing the excessive-carbon steel wire rod by means of 9 molds in sequence in order to produce a metal wire. Low-carbon wire rod in coils is used for wire drawing, in addition to to manufacture metallic mesh and metalware. Rising the carbon content in steel can improve the energy, but also causes severe problems like centerline segregation. High carbon steel wire rods used typically in prestressed concrete wires, suspension bridge cables, and varied wire ropes should have excessive strengths and satisfactory ductility after wire drawing and, in addition, should have good drawability from the point of view of productiveness. The key necessities for this product are the absence of any wire drawing breakage and floor defects, as well as uniform geometry and mechanical properties.

Minimal segregation is made possible by the continuous casting system, which is provided with an automated control and regulation system of the solidification and electromagnetic stirring parameters, and by casting with a really exact overheating temperature, thereby preventing the formation of cementite within the central area of the wire rod. The heat therapies generally applied to steel wire rod, either before or throughout processing into wire, embrace annealing, spheroidize annealing, patenting, and managed cooling. In the case of a mixed construction, the ferrite particle measurement and pearlite nodule size were collectively measured. SW-A steel wire is processed by warmth-therapy and cold-work (drawn), so it has high hardness but low in tensile energy and used to make metal nets and regular wire materials. Compared with electro galvanization, hot-dip galvanization deposits not only a thicker zinc layer, but additionally a strong layer of zinc iron alloys on the surface of iron wire, which improve the power of corrosion prevention of iron wire. The resulting steel does not have the structure composed primarily of pearlite and hence is poor in energy. Wire rod is a protracted steel semi-finished product manufactured by scorching rolling billets on steady rolling mills. Offered are: a excessive carbon metal wire rod which is sufficiently reduced in hardness and is able to lowering the spheroidization time throughout the production thereof; and a technique for producing a high carbon metal wire rod.
In order to make the ferrite crystal grain measurement 20 μm or much less as defined within the present invention, it is mandatory to control the finish rolling temperature in the hot rolling process and the cooling fee after finish rolling. Besides, including of Cr causes a continuous cooling transformation curve of the metal to shift to the best, in order that the distances between pearlite layers change into smaller underneath the same cooling velocity. When the excessive-carbon metal wire rods of Embodiments 1-11 are in contrast with those of Comparability Examples 1-four, they have superior mechanical properties, including excessive mechanical strength with an average tensile strength of 1568MPa in addition to good plasticity with an average after-fracture shrinkage charge of 33% and a mean after-fracture elongation share of 9%.
