Iron and steel complex: An Iron and steel Complex groups all the processes of transformation of the Steel from the iron mineral to the end item, whereas the Steel is that one that makes elements of Steel from another Steel or the iron. The process the process begins with the production of the cast iron which is an intermediate product generated by means of the reduction of the Iron with the aid of the coke and limestone stone, in this state the iron this completely liquid this normally is realised in denominated the high furnace which founds and reduces of continuous way great amounts of Iron thus is identified as it practices usual to handle it the logistics of this type of industry by means of a robust collection of railway wagons. It is obtained as product the cast iron enl what can have two presentations in ingots or liquid which is transported towards the following phase. The second step is to retire the impurities of the cast iron such as the coal, phosphorus, silica, etc are used many processes but most efficient it is the reduction with I oxygenate LD, although traditionally success has been handled to the Bessemer process by far, additionally other elements are added in this instance that help to improve the properties of the Steel and which they depend on the alloy that is desired to obtain, such as the manganese, nickel, chromium, etc As third step we have this Steel refining direcciona of two ways, first can be to the continuous casting and second it is the classic tap, if the first option is chosen the product that is obtained are the tochos of Steel which they are not but that cylinders of diameters and normados sizes in which aluminum has been added to facilitate that the dreg leaves afloat, the classic tap however founds on ingot-molds the Steel of such luck that, as sees the intention is the same but the yield requirements are those that they prevail in the continuous casting, the following step is the conformed one proper that is the one that gives to its final form as laminated profiles or plates him in the heat of the moment or fried, which are different in which the made elements in the heat of the moment form from certain molds that his conformed determines by smelting whereas in cold it is obtained from plates that are conformed until having the condition asked for by the client, this process is generally the dubbing although they excite the laminates in also fried printing product. This type of plants also considered as integral has the following listing of processes at least: Coke ovens High Furnace Molded Steel mill Trains of Lamination dressing chisels Trains of Lamination of finished Trains of Lamination in cold As it is possible to be identified this types of processes are determined essentially by the needs of market nevertheless the being defined this is not easy the change from a model to another one since the shutdown of these processes usually generates a profit dismissed of consideration.
