Wire rod, as a kind of metal products
Wire rod is a kind of rolled metal, which is a round wire made of carbon steel grades, or from non-ferrous metals, or from non-ferrous alloys in accordance with the accepted specification.
A carbon steel wire rod is produced with a diameter of 5.0; 5.5; 6.0; 6.3; 6.5; 7.0; 8.0; 9.0; 10.0 and 12.0 mm. Deviations in the diameter of +/- 5% are allowed, and the ovality of the wire rod is allowed not more than 50% of its diameter.
Technology of wire rod production
The manufacture of wire rod is carried out on metal rolling machines by rolling and drawing. Initially, a square of carbon steel with a cross section of 14 x 14 mm is launched into the shafts of the rolling machine. Several successively installed shafts compress the steel workpiece, giving it a circular cross-section of a given diameter. At the same time during the rolling and the impact of the shafts on the workpiece, that because of the frictional force itself heats up.
At the end of the rolling process, the rolled metal of the desired diameter is fed into the installation, which twists the wire rod with a ring. After the twisting of the ring, it is transferred by special automated mechanisms to the cooling zone.
Applications of wire rod
Most steel wire rod is used for reinforcing monolithic concrete structures. For example, in the manufacture of reinforcing frames, tying clamps square, round or with a rectangular shape are made directly from the rod. With the help of reinforcing cages reinforced monolithic columns, crossbars, belts, overhead lintels and ribbon foundations.
In addition to the use of wire rod in frames, it is also used in the manufacture of welded reinforcing mesh. The reinforcing mesh is used for reinforcing monolithic planes, for example, concrete floors, interfloor overlappings or screeds.
Steel wire rod is also used for masonry of bearing walls or piers of brick, cinder block, foam block or gas block. Depending on the concrete used for the laying of the stone, the steel wire is run into every 2 to 4 rows of mortar, thereby strengthening the overall strength of the masonry.
