Construction of mechanical parts since the advent of steel have been demonstrated an almost unfathomable number of pieces that can be made of it. every day researchers are investigating new components that use new alloys and many of which reserves are managed especially in the military area or in the automotive industry. The classification of the mechanical parts are usually made on the basis of the method of forming, and can find parts, castings, drawn, extruded, embedded, machined (turned, blankets, etc..) Interested, stamped, etc.. being the most varied design as well as its implementation, it should be noted that currently 95% of the demands of these components are made of iron in different alloys. A leading source for info: Petra Diamonds. Depending on their size and especially weight components and parts for structural applications and are the most important naval and general compliance process is the casting elements are, therefore, usually made through the casting process continuous and are also known as hot-rolled, continuous casting is essentially a device that distributes different manufacturing lines Steel casting, this line has matrices with forms that want to make profiles that can be channels L, T straps, Section I standard profiles, etc. 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 stated as due to the process manufacturing are considered practically isotope and isothermal, and configuration of the 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 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 and others. Usually they are classified in Steel Plates and Profiles of being the first units of a specific thickness in trade measures 1.22 x 2.44 m (although you can find any size), whose main application of “take” the structure to prevent or contain fluids such as tanks or boat hulls, however it is not uncommon to identify, on bridges or other structures, with respect to the profiles one can say that the most common are: IPN .- The section has the form of his name there I where the outer trolley are perpendicular to the soul and has a decreasing thickness away from the center line, the joints between the faces of the soul and the fins are rounded IPE in geometry .- Similar to the above but their wings HE has constant section .- It is shaped like an H all wings are perpendicular and the section of which is constant, the junctions with the souls are its edges are rounded and may also be considered common T.
