Additional, in keeping with Patent Doc 2, a high carbon chromium bearing metal having a predetermined component composition is rolled while being managed so that the temperature in the whole cross part is between the A1 level and the Acm point from extraction to finish rolling. Integration of the above analysis has achieved industrial software in additional than 10 steelworks and was further extended to application in spring metal, welding wire metal and another wire rods. The highest supplying international locations or areas are United States, China, and Vietnam, which supply 1%, ninety eight%, and 1% of high carbon steel wire rod respectively. Rod for the manufacture of carbon steel wire is produced with manufacturing controls and inspection procedures meant to ensure the degree of soundness and freedom from injurious floor imperfections needed for specific applications. The wire rods were then subjected to lead patenting, acid wash, and bonderizing and drawn to a diameter of zero.95 mm using a dry high-velocity wire drawing machine (at a die approach angle of 12 levels) in go schedules given in Table 4 Table 4(a) and Desk 4(b) below, from which drawn wires of various diameters had been sampled.

In order to make the ferrite crystal grain size 20 μm or much less as outlined within the current invention, it is mandatory to control the end rolling temperature within the hot rolling course of and the cooling rate after finish rolling. Moreover, including of Cr causes a continuous cooling transformation curve of the steel to shift to the appropriate, so that the distances between pearlite layers develop into smaller under the same cooling pace. When the excessive-carbon steel wire rods of Embodiments 1-eleven are compared with these of Comparison Examples 1-four, they have superior mechanical properties, together with excessive mechanical power with an average tensile strength of 1568MPa in addition to good plasticity with a median after-fracture shrinkage fee of 33% and a median after-fracture elongation proportion of 9%. Particularly, the product of Embodiment 11 has a tensile strength of 1575MPa, an after-fracture shrinkage price of 36% and an after-fracture elongation share of 10%, and thus has the most passable mechanical efficiency. The present invention relates to a excessive carbon metal wire used as a bearing materials in vehicles and varied industrial machines and a method for producing the high carbon metal wire. The lower limit of end temperature must be greater than 800° C., ideally larger than 900° C., so as to keep away from extreme load on the rolling mill. Materials embrace coke, steel, stainless-steel, non- oriented electrical silicon metal, ore and iron, pig iron, alloys and tinplate. No. 26 underwent cooling starting from a high temperature (Desk 2), suffered from insufficient contents of precipitates equivalent to TiC, and failed to provide satisfactory drawability. Normal use wire rod is often made from low carbon metal and is zinc plated to stop corrosion. Extra particularly, the current invention relates to high carbon metal wire rods having higher drawability. In the meantime, V tends to precipitate between ferrite in pearlite through the part transformation process, thereby having a precipitation strengthening effect on the high-carbon steel wire rod, which is useful for growing the energy of the high-carbon metal wire rod.
