FREMGANGSM}TE OG APPARATUR FOR DIREKTE REDUKSJON AV JERNMALM |
摘要 |
A process and apparatus for the gaseous reduction of sized iron ores wherein a steam-hydrocarbon fluid mixture, having a steam : carbon molar ratio ranging from 0.9:1 to 1.8:1, is catalytically reformed to produce a reducing gas mixture containing about 85 to 98 percent by volume carbon monoxide plus hydrogen, with a hydrogen:carbon monoxide volume ratio of at least 2:1. The reducing gas is transferred directly at elevated temperatures to a shaft furnace for reduction of ores therein, and the spent reducing gas is cleaned, cooled and dried, for use as fuel and/or cooling the reduced ores. |
