Abstract

Liquid-phase reduction processes are the new and effective alternative to the cokeagglomerate-blast furnace technology of ironmaking. To date, there is no doubt in the efficiency of a large number of processes of liquid-phase reduction of iron. We have developed mathematical models which make it possible to select the most effective technology for specific conditions on the basis of certain criteria of optimization and speed limits. We created a dynamic simulator of liquid-phase reduction process which provides the development and improvement of the methods of process control.
