The integrated route for the steelmaking and the pollution sources

This paper is focused on the description of the integrated route for the steel production (Figure 1). The main plants involved in such a route hare been treated and the main process steps have been described: sintering of the iron ores, coal treatment to obtain the coke, pig iron production by the blast furnace and Us conversion to steel by the basic oxygen furnace. During the description of these plants and processes, the main pollution source have been pointed out. Finally, a synthetic presentation of the plants used for the reduction of the iron ores by natural gas has been performed.
