Ideally greater than 900° C., in order to avoid excessive 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 inadequate contents of precipitates resembling TiC, and failed to supply satisfactory drawability. Basic use wire rod is usually product of low carbon steel and is zinc plated to forestall corrosion. Extra particularly, the current invention pertains to excessive carbon steel wire rods having higher drawability. Meanwhile, V tends to precipitate between ferrite in pearlite during the part transformation process, thereby having a precipitation strengthening effect on the excessive-carbon steel wire rod, which is helpful for increasing the strength of the high-carbon metal wire rod. Producer of carbon metal wire rods. We’re aware of a number of utilities of our merchandise and have all the necessary technical and human assets to guarantee their optimum high quality. For that reason, the wire rod of the current invention has superior drawability despites its low energy, and hence it permits high-speed drawing with out breakage and it extends die life.
1960MPa degree bridge cable zinc-coated metal wire
We are a leading provider and distributor of the very best high quality carbon steel wire on the market. In order to make the ferrite crystal grain measurement 20 μm or less as defined within the current invention, it is mandatory to regulate the finish rolling temperature in the sizzling rolling course of and the cooling rate after finish rolling. Apart from, adding of Cr causes a steady cooling transformation curve of the metal to shift to the precise, in order that the distances between pearlite layers change into smaller beneath the identical cooling pace. 1960MPa degree bridge cable zinc-coated metal wire. When the high-carbon steel wire rods of Embodiments 1-11 are compared with those of Comparability Examples 1-four, they’ve superior mechanical properties, together with high mechanical strength with a mean 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%. Especially, the product of Embodiment 11 has a tensile power of 1575MPa, an after-fracture shrinkage fee of 36% and an after-fracture elongation proportion of 10%, and thus has essentially the most satisfactory mechanical efficiency. The current invention relates to a high carbon metal wire used as a bearing materials in automobiles and numerous industrial machines and a technique for producing the excessive carbon steel wire. The decrease restrict of finish temperature ought to be increased than 800° C. High Carbon Steel Wire Rods. prestressed concrete 7-wire strand 15.2mm pc ht steel strand size
2300MPa stage pre-stressed steel strand
King Steel provides steel wire rod in any carbon, alloy or stainless grade, and in various qualities. The upper restrict of its content material is subsequently set at 0.40%. Use of the high-carbon steel wire rod in accordance with any certainly one of Claims 1-3 for producing 2300MPa stage pre-burdened steel wire, 2300MPa stage pre-stressed steel strand, and whether or not high carbon metal wire rod is non-alloy, or is alloy. With a content more than zero.9%, manganese deteriorates drawability as a result of extreme solid-answer strengthening of ferrite. Community cementite, martensite, pearlite, band structure, texture, and so on., are necessary buildings of high-carbon steel wire rods 18 , 19 , 20 Typically, high-carbon steel for the production of steel wire strands, metal cords and noticed wires is hypereutectoid metal with a carbon content of greater than 0.78 wt.%; a hypereutectoid transformation will happen throughout cooling and secondary cementite will precipitate alongside the grain boundary to form a steady or discontinuous community. In keeping with the present invention, the construction of the wire rod is characterized by a big space ratio of pearlite (ideally larger than ninety five area %). The wire rod could be poor in drawability if different structure than pearlite (e.g., ferrite and bainite) accounts for more than 5%. By the way, ferrite lowers strength and hence the final product (steel wire) with ferrite is poor in power. Depending on its composition and characteristics, the wire rod is available in low, medium and excessive carbon steels (between zero.05% and 0.86%) with different alloy grades (Al, B, Cr, Mn, Mo, P, Si, S, etc.). As well as, wire rods will be provided in round or hexagonal shapes, in different coil formats and with all kinds of thermal and superficial treatments. In our broad array of merchandise, we provide a wide range of Wire Rods in customary in addition to customized form. Excessive-carbon metal wires used for bridge cables, tire reinforcement materials and cutting supplies of silicon ingot for photovoltaic trade require an especially effective diameter and high strength. SW-C metal wire has superior tensile power and is often used as spring materials. In contrast, work hardening is suppressed in the wire rod or wire reworked in two steps in line with this invention since it is in a state of coarse cementite dispersed in ferrite. The recent rolling start temperature, nevertheless, is successfully set to 850° C. or larger.
