A PROCEDURE IS PRESENTED TO PRODUCE IRON IN LINGOTES USING THE DIRECT REDUCTION OF THE IRON LESS IN A PRE-REDUCTION STAGE FOLLOWED BY A FINAL REDUCTION STAGE. IN THE PRE-REDUCTION STAGE THE IRON LESS IS PRE-REDUCED IN A FUSION CYCLONE (1) THROUGH A REDUCTION PROCESSING GAS ORIGINATED FROM THE FINAL REDUCTION STAGE. A POS-COMBUSTION IS PRODUCED IN THE REDUCTION PROCESSING GAS IN THE FUSION CYCLE THAT THE IRON LESS IN THE FUSION CYCLE IS BASED AT LEAST PARTIALLY. THE IRON MENA PARTIALLY FOUNDED PASSES DOWN TO THE INSIDE OF A METALLURGICAL GLASS (4) LOCATED BELOW THE CYCLONE IN WHICH THE FINAL REDUCTION IS PLACED THROUGH THE SUPPLY OF COAL AND OXYGEN, FORMING IN THIS FORM A PROCESS GAS REDUCTION. A PARTIAL POS-COMBUSTION IS PRODUCED IN THE REDUCTION PROCESSING GAS IN THE METALLURGICAL GLASS THROUGH THE OXYGEN SUPPLIED TO THE SAME. THE PROPORTION OF POS-COMBUSTION OF GAS THAT COMES OUT OF THE METALLURGICAL GLASS IS NOT GREATER THAN 0.55. THE CARBON IS SUPPLIED DIRECTLY TO THE INSIDE OF THE ESCORIA LAYER (7) SO THAT THE PARTIAL POS-COMBUSTION IN THE METALLURGICAL GLASS IS EFFECTED AT LEAST PARTIALLY IN THE ESCORIA LAYER.
