Control of pollution in the steelworks. A steelworks in addition to electric furnace must have rolling mills, these in order to reduce costs, are usually located in the vicinity of the furnace, and consist of a carefully distributed set of rollers which continuously decreasing section of the lever until the final product is obtained, it can be wire rod, plate, steel angleRods with protrusions or corrugated, plates of steel, etc is clear that for each of these steel products requires specialized equipment. It is important to point out that in the steelworks generated powder handling should be performed carefully since this type of industries are especially audited, by the departments of Government emissions control, robust systems for fume extraction which purify them and cool prior to their discharge to the environment, is designed so it is expected that the heat is extracted from these, is used in other processes of steelmaking, the extraction system also has an additional feature that is to regulate the pressure inside of the sill. The main pollutants are CO2, H2S, ashes, which has serious implications for health and environment, since both are desplazantes agents of the oxygen. For its part the acid sulfide H2S from 50 ppm has a narcoticising effect and from the 100 ppm produces death, this gas is heavy and falls which is in the proximity of people. However it has a rotten egg smell that makes it detectable, although when she already perceives it can be too late. These elements produce strong opacity especially the ashes, which are used very robust filtration systems especially the so-called cyclonic filter, which are particularly useful, since they become not clogged as conventional ones, since the flow is tangential to the axis of the filter, which causes the particulate matter trapped, rushing to the bottom of it. Another way to control pollution especially what CO2 meant using catalysts which caught it but it is an expensive option and few companies apply it.
While it is true that concern type in the cleanliness of the air also, the same temperature is a problem, by which must be cooled by previous exchangers discharge to the environment, the heat thus retrieved usually is used, blending the bunker, which has an important application in the heating of other areas of the steelmaking process. It tends to be important also, the noise control within the premises of the steelworks, unfortunately the nature of the work developed there, this purpose is not easy to run, reason why the use of ear-muffs or similar elements strives to protect the person. Other means of minimizing the impact on health consists in having fireplaces enough (60 meters) high in order to keep away the gases, the more possible of the population.
