Steel Forming is associating steel to steel producers that are obtained after reduction of scrap and / or cast iron through a lamination process. classified into two major groups that correspond to the hot-rolled and cold rolled. Hot-rolled are all elements that are obtained through what is called continuous casting processes and consist primarily of a device that distributes different manufacturing lines Steel casting, this line has matrices with forms that want to make Profiles can be channels L, T straps, Section I standard profiles, etc, a very important element of this type of construction is Alambronn which is not nothing but a metal product which is obtained by a hot rolling process thanks to a specially designed train for this effect, known as rolling mill, wire rod is circular or oval section that varies between 5 and 30 mm outside diameter, which is usually rolled coils of hundreds of meters, you can say that the applications of this product are varied, another important output is the same plate or plate metal plates that are 6 m lengths of steel or other material its usefulness is very wide, are usually constructed in the final form at the steel mill as a product. The continuous casting molds are cooled by water and allow the formation of long stretches of the items listed above, the implementation is fundamentally the same structure as due to the manufacturing process are considered practically isotrope and isothermal, and configuration material constant throughout its structure, therefore design techniques may be applied if inconvenient (correction factors) to the structural design. Forming addition described above is necessary to control the cooling conditions so that these items be ductile because rapid cooling can cause the irregular hardening resulting in fragility product. The composition of this product may vary depending on the application and the process used but is very common to find it with carbon contents of about 0.8%, proportions of other elements such as phosphorus of 0.48%, 0.30% manganese and others are cold rolled those elements that leave the metal plate and after a machining process acquired its final shape, machining processes usually zizalla by cutting and folding, these elements due to machining stress concentrations occur along the same they change their crystal structure tend to be tougher in these areas but also more fragile, which recommends the adoption of specific computational techniques, safety factors associated with this uncertainty in the charge distribution can be found in the form of channels C, G, angles, etc.. have their main use the so-called ornamental metalwork or without any problems and are often cheaper because those making is local while the first in their vast majority are imported and expensive the shipping weight.
