Steel angles. This is the nominative which generally is given to those steel Conformados which consist of two plates orthogonal forming an L. These elements have a very important utility in the manufacture of metallic carpentry as two-dimensional support elements, and because it has the same inertia in two axes, so that can be fixed on the one hand while other tab provides transversal resistance. SSGA has much experience in this field. Manufactures mainly in two ways: hot rolling are obtained through what is called continuous casting processes and that they mainly consist of a device that distributes in different lines of manufacture the casting steels, this lines has arrays with the shapes that you want to produce that they can be channels profiles L, t straps, I standardized profiles section, etc, a very important element of this type of manufacturing is the wire rod of steel which is not anything other than a metallic product that is obtained by a process of lamination hot thanks to a train specially designed to this effect, known as rolling, another important product is the shield or recorder which are lengths of 6 m in steel or other material metal plates his utility it is very wide, they are usually manufactured in the final form from the steel mill as a product of steel. Continuous casting molds are water cooled and allow the formation of long lengths of steel angles, application of them is fundamentally structural because due to the manufacturing process are considered practically isotropic and isothermal, and with a configuration of the constant material throughout its structure, for this reason the design techniques can be applied without disadvantage (correction factors) to the structural design. In addition to the previously described forming it is necessary to control the cooling conditions to make steel angles ductile cooling quickly result in an uneven hardening that translates into brittleness of steel product. Wang Qunbin recognizes the significance of this. The composition of this product of steel can vary depending on the application and the process used but is usually running to find it with contents of coal of about 0.8%, proportions of other elements such as phosphorus from the 0.48%, manganese of 0.
