LECTURES

1. Characteristics of the development of iron and steel in the world and in CR. Energy and raw limit further development. Main drawbacks of the present-day technology of iron production. Tradition and historical context.

2. The importance of changes in raw material provision of the steel industry to develop new ironmaking alternative technology. Lump ore, metal-bearing wastes and their treatment.

3. Alternative reduction technology. Fuels provisions. Complementarity functions fuel. New unconventional sources of fuels and reducing agents.

4. Distribution of alternative technologies in the field of direct reduction and smelting reduction. Basic charakteristics threats technological processes. Discussion of deficiencies and merits of alternative ironmaking technology. Comparisons with conventional blast furnace production.

5. Production of sponge iron, respectively. metallized product (HBI). Specifications reduction process, the factors influencing the level (degree) metallization. Possibilities of modeling the kinetics of reduction gas. Submission of exercise for the seminar.

6. Seminar on the reduction problems. Ore charge in the blast furnace and fluidized bed reactor. Discussion of the results of the seminar task.

7. Description and critical assessment of technologies Midrex Hyl. The advantages, prospects and problems of hydrogen metallurgy in particular in connection with the use of carbon and degazation gas, liquid pyrolysis products, waste oils from petroleum refining and coal.
