Highlights: Blast Melting Technology without Coke

-Studying a pattern of transition to the technology without coke (TWC) On the basis of BF-evolution.

-The key problems of TWC is the ability to use ash coals and rebuilding BF in shaft-hearth Unit (SHU)

-Studying the new technology by physical and mathematical models.

-TWC can be organized by reconstruction of BF, the term of payback < 1 year.
