The use of wire is mainly summed up in two kinds: one for building materials, two for drawing raw materials. Used for building materials, steel grades have ordinary low-carbon steel, high-quality carbon steels and steel and so on. The variety has a round and threaded shape, the size of the diameter of 6~25 mm is the most used, the diameter of 28~32 mm is also often used. As a building material, it is required to ensure chemical composition and weldability, which requires uniform and stable physical properties to facilitate cold bending, cold drawn and cold drawing.
Construction of various specifications of the diameter of the wire are expected to be coil-like delivery, so that the length of the need for arbitrary interception so as to avoid waste. As the wire drawing material, although more steel, but the variety is only round. To reduce the number of pulls, the diameter is generally 5~9 mm, for special purposes also use wire diameters greater than 10 mm.
As the wire drawing material, the requirements to ensure that the chemical composition and physical properties are uniform and stable, metallurgical microstructure as sorbite as possible, the size should be accurate, the surface should be smooth, iron oxide thin skin and clear. In general, the use of wire is very wide, in the national economy in all sectors of the wire occupies an important position. Some wire rod rolling can be used directly, mainly for reinforced concrete reinforcement and welded structural parts used, and some are used as reprocessing materials, after reprocessing. For example, after drawing into a variety of steel wire, and then by twisting to become a wire rope, or re-woven into the wire mesh, after hot forging or cold forging into rivets, after cold forging and rolling into bolts, and through various cutting and heat treatment of machine parts or tools, through the winding molding and heat treatment made of spring;
