Wire rods are mainly used as raw materials for reinforcing and welding structural parts of reinforced concrete or for reprocessing (such as wire drawing, nail making, etc.). According to the steel distribution catalog, the wire rods include ordinary low carbon steel hot-rolled wire rods, electric wire rods, wire rods for blasting lines, quenched and tempered threaded wire rods, and high-quality wire rods. The widely used wire rod is mainly an ordinary low carbon steel hot-rolled wire rod, also known as an ordinary wire rod. The weight of the disc is 100-200kg, and now it is mostly rolled on a non-twisted high-speed wire rolling mill and controlled cooling after rolling. The maximum disc weight of 5.5-22.0mm in diameter can reach 2500kg. Ordinary wires are mainly used for construction, wire drawing, packaging, welding rods, and the manufacture of bolts, nuts, rivets, etc. High-quality wire rod only supplies high-quality carbon structural steel hot-rolled wire rod. Such as ML08AL, 08F, 10b21, 35Mn, 50Mn, 65, 75Mn, etc. Used as raw materials and other structural parts of metal products such as steel wire, and other high-quality steel rolled wires. It is customary to include high-quality profiles above 8mm, and metal products below 8mm.
Wire rod is one of the most widely used steel varieties. After rolling, it can be directly used for reinforcement and welded structural parts of reinforced concrete, and can also be used after reprocessing. For example, it is drawn into various specifications of steel wire, then twisted into steel wire rope, woven into steel wire mesh, wound into shape, and heat-treated into spring; through hot and cold forging into rivets and cold-forged and rolled into bolts, screws, etc.; Cutting into heat treatment to make mechanical parts or tools, etc.
Wire rods are generally made of ordinary carbon steel and high-quality carbon steel. According to different steel distribution catalogs and uses, wire rods include ordinary low-carbon steel hot-rolled round wire rods, high-quality carbon steel wire rods, carbon welding rod wire rods, and quenched and tempered threaded wire rods, wire rods for wire ropes, and wire rods for piano wires. And stainless steel wire rods, etc. my country is the largest wire rod producer in the world, with annual output accounting for more than one-third of the world's total production. Wire rod is also my country's second-largest steel production variety. The proportion of domestic steel production has always been high. In 2007, domestic wire rod production accounted for my country's steel production. 14.2% of the total output. In recent years, the growth rate of domestic wire rod output is basically the same as that of domestic crude steel output, which is maintained at around 20%. From the perspective of the import and export of wire rods, wire rods have long been my country's main steel export varieties, and also the steel varieties that my country has maintained a net export status, especially in recent years, the export growth has been particularly rapid. In 2007, my country exported 6.238 million tons of wire rods, an increase of 684,000 tons over the previous year, a year-on-year increase of 12.3%; and imported 614,000 tons, a decrease of 91,000 tons over the previous year. From the perspective of domestic wire rod consumption, wire rod is widely used in the construction field. Since 2000, driven by the strong domestic investment demand, domestic wire rod consumption has also maintained rapid growth.
