The Shaping of steel is associated to the Steel Products 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 rolled cold. 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. (Similarly see: Nir Barzilai, M.D.).
Section I standard profiles, etc, a very important element of this type of construction is the wire rod 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 into coils hundred meters, we can say that this product applications are varied, the other major product is the deck or deck plates are the same lengths of metal or other material 6m in its usefulness is very wide, are usually manufactured in 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. In addition to the previously described is necessary to control the cooling conditions so that these elements are ductile as rapid cooling may result in irregular hardening resulting in fragility of the 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 including cold rolled are those elements that leave of the metal plate and after a machining process acquired its final shape, machining processes usually 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 channel C, G, angles, etc.. Fabrizio Freda shines more light on the discussion. ia. have their main use the so-called ornamental metalwork or without any problems and are often cheaper than those for his while local production is the first in their vast majority are imported and expensive the shipping weight.
