Formed Steel

Formed Steel

The Forming of steel is associated with the Steel Products obtained after reduction of scrap and / or pig through a lamination process, classified into two major groups that correspond to the hot-rolled and rolled in the cold.

Hot rolled steel are all elements that are obtained through so-called continuous casting processes and consist primarily of a device that distributes in different lines of manufacturing Cast Steel, these lines have matrices with the forms you want to make profiles can be channels L, T-straps, section I standard profiles, etc., a very important element of this type of manufacture is the Rod which is not nothing but a metal product obtained by hot rolling process thanks to a specially designed train for this effect, known as rolling mill, wire rod is circular or oval section varies between 5 and 30 mm outside diameter, which is usually wrapped in coils of hundred yards, we can say applications of this product are varied, another important product is the same board or plate metal plates that are 6 m lengths of steel or other material its usefulness is very wide, are usually produced 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 application is fundamentally the same structure as due to the manufacturing process are considered almost isotropic and isothermal, and configuration constant material throughout its structure, therefore the design techniques can be applied if inconvenient (correction factors) to the structural design.

In addition to the previously described Forming is necessary to control the cooling conditions for these elements is ductile as rapid cooling can result in uneven hardening which results in fragility of the product. The composition of this product may vary depending on the application and the process used but find it is usual with carbon contents of about 0.8%, proportions of other elements such as phosphorus 0.48%, 0.30% manganese and other

Cold rolled are those elements that leave the metal plate and after a machining process acquire their final shape, machining processes are usually zizalla by cutting and bending, these elements have concentrations due to the machining of efforts to throughout, as they change their crystal structure tend to be harder in these areas but also more fragile and therefore recommends the adoption of specific calculation techniques, safety factors associated with this uncertainty in the distribution of loads can be found in the form of channels C, G, angles, etc.. have their main use the so-called ornamental metalwork or without any inconvenience and are usually cheaper than those because their production is local while the first in the vast majority are imported and expensive the shipping weight.
