Abstract
Greenhouse gases changing the climate of Earth, carbon dioxide in particular, are by-products and are released into the atmosphere in large quantities by enterprises of ferrous metallurgy. The problem of greenhouse gas emissions has become one of the major environmental problems connected with the smelting of steel at metallurgical enterprises and requires an urgent solution. In the present article competitiveness of products of enterprises of ferrous metallurgy is analyzed, taking into account ecological factors of production. So-called greenhouse or "carbon" competitiveness is considered. Such major indicators of production as energy costs and the cost of production are the focus of attention.
In the article a complex of new indicators of competitiveness of metallurgical enterprises is introduced and processes which are characterized by the minimum emission of carbon dioxide are described. A method of calculation of these indicators is given considering so-called carbon footprint, energy consumption of steel smelting and product costs. Values of the specified indicators are defined at various combinations of the metallurgical processes that result in steel smelting. Various chains of technology applied to steel making in such facilities as the blast furnace (BF) and the oxygen converter, BF and the arc furnace (AF), the Corex process and AF, the Romelt unit and AF, the Midrex process and AF, and also the Hyl-III process and AF are subjected to the analysis.
In conclusion, analysis of the received results is carried out taking into account the advantages and shortcomings of the considered technological chains of the metallurgical conversions, the ranking of technological processes of at enterprises according to proposed indicators of competitiveness is carried out, and the general conclusions are drawn as to the priority of the steelmaking technologies in use.
Keywords
Key words: competitiveness indicator, product cost, carbon footprint, emission, chains of processes of ferrous metallurgy.
