Summary
The subject is focused on improvement basic knowledge of alternative technologies outside the blast furnace ironmaking only for Ph.D. students. Analysis of basic contemporary trends in pig iron production. Main ways of blast furnace technology modification. Principal changes in blast furnace aggregate operating, in raw materials composition and energetic security of the process. Technical equipment of aggregates. Complex automatic system of operating, coke replace by dust coal, oxygen, pellets, metallized charge application. Processing of pig iron and modification its characters out of blast furnace. Alternative methods of iron production. The most widespread ways of direct reduction within pig iron production in Czech conditions.
