Steelmaking. In the manufacturing process elements have two possible routes: the first, corresponds to that obtained from virgin ore Anthracite corresponding to a steel complex and the second to that obtained from the scrap steel or iron material Direct-reduced (iron) the industry that is dedicated to the latter is called Aceria, this process is to melt the material by an electric furnace and then casting the obtained material to manufacture ingots and / or steel billets. An addition Aceria oven must have mills, these with the aim of reducing costs, usually located in the vicinity of the oven, and consist of a set of rollers carefully distributed them on a continual basis are diminishing section Steel billets until the final product of steel, it can be wire, Platina, steel angles, rebar, plates, etc. it is clear that for each of these steel products requires specialized equipment. It important to note that in the management of steelworks dust generated should be done carefully because these industries are particularly audited departments at government control of emissions, so robust is designed for the exhaust systems that purify and cool the gases produced prior to discharge to the environment, it is expected that the heat is extracted from these, to be used in other processes, the extraction system also has an additional role to regulate the pressure inside the sill .
The Aceria must also possess large warehousing facilities for both the raw material for finished steel products, equipped with a very good transportation system overhead cranes are usually used for this purpose, but their applicability is usually restricted particularly as regards the management of raw material, which prefers the use of extensible crane equipped with "octopus" in the end. An important point to stress is that it consumes much power for this reason often accompanied by electrical substations or generating systems themselves, as you can identify the Aceria is a complex industry, requiring skilled and trained. As may be evident, is also important the management of logistics associated with transporting materials in large quantities, which must be provisioned respective facilities, ie good roads, better rail and desirable proximity to a port if it is not your own. Many work with iron, so the proximity to the blast furnace is a need, this makes production more affordable, but the high energy cost of processing a material from the ore is obviously higher than from Junk and only comparable with huge steel production, it is considered that for a process of obtaining steel from virgin ore must be profitable to produce at least 2 million tons of steel per year.
