1. History

As shown in figure 1 , this is a process for producing liquid cast iron which :

• takes over the fusion reactor, the "melter-gasifier" of the COREX process;

• targets the direct use of iron ore fines (less expensive than graded ores and, above all, pellets);

• replaces the COREX shaft furnace with reactors for preheating and reducing iron ore fines in fluidization.

• The development of this process is shown in table 1 and the evolution of this method can be seen in figures
