A steel complex includes all the processes of transformation of steel from iron ore to finished product, while the steel is one that manufactures steel elements from other steel or iron. The process The process begins with the production of pig iron which is an intermediate product generated by reducing the iron with the help of coke and limestone in this state is completely liquid iron that is usually done in the blast furnace called the which melts and continuously reduce large amounts of iron which is identified as a usual practice to handle the logistics of this type of industry through a robust collection of railway cars. Product is obtained as enl cast iron which can have two shows in bars or liquid which is transported to the next phase. The second step is to remove impurities such as coal, iron, phosphorus, silica, etc. Many processes are used but the more efficient the oxygen reduction with LD, although traditionally Bessemer process has managed very successfully, additionally in this instance are added other elements to help improve the properties of steel and depend on the alloy is desired, such as manganese, nickel, chromium, etc. As a third step we Steel refining that is addressed in two ways, the first may be a continuous casting and the second is the traditional casting, if you choose the first option, the product obtained are steel billets which are nothing more than cylinders of diameters and size standards in aluminum has been added to facilitate the scum out “afloat”, the classic cast ingot instead relying on the steel so that, as we see the intention is the same but the performance requirements are which prevail in continuous casting, the next step is forming itself which is what gives it its final form as profiles or plates hot rolled or cold, which differ in that the elements are manufactured from hot of certain molds that determine compliance by cast cold while you get a plate that is shaped to have the condition requested by the customer, this process is generally excite bending but also cold-rolled product in print. Such plants are also considered integral with at least the following list of processes: Coke Ovens Blast Furnace Cast Trains Aceria roughing rolling mill finish cold rolling mill can be identified as the types of processes are determined primarily by market needs to be defined but this is not easy to change from one model to another and that stopping these processes often generate considerable profits.
