Resumo
Steel-making is globally based on hot metal refining in basic oxygen furnaces. At present and in perspective iron ore and coal remain the main primary materials for iron-making. Available processes of iron-making without a blast furnace are far behind the blast furnace process in terms of productivity and total through-out consumption of fuel for production of hot metal which includes the costs of coke and agglomerated raw materials production, hot blast and oxygen generation. Blast furnace process is the leader in terms of the amount of hot metal production with minimal production cost and in the near future can not only reserve the leading role but significantly reduce the cost for iron-making and the environmental impact. This possibility is related to the prospective use of self-reducing ore and coal briquettes made of concentrate and cheap coal-containing materials in blast furnaces. The process can also be further intensified by using oxygen and increasing the pressure within the furnace.
