| titleOfInvention | Method for producing high-grade reduced iron by magnetic separation of coal-based gas-coal double-base coking roasting |
| abstract | The invention relates to the technical field of energy-saving and comprehensive utilization of mineral resources, and relates to a method for producing high-grade reduced iron by coking, roasting, and magnetic separation of coal-based gas-coal double-base; Coal double-base upgrade roasting, and the coking coal is separated by a medium magnetic separator, and then the secondary reduction material >300 mesh is obtained by crushing and magnetic separation ball milling to obtain a secondary reduction material >300 mesh, and then a medium magnetic separation device is used to obtain a reduced iron powder product >300 mesh; The method uses coking flue gas to reduce iron ore with TFe>45%, optimizes the iron powder grade TFe>77%, and solves the problem that the reduced iron raw material requires TFe>68.5%; at the same time, the coking flue gas reduces coking pollution and reduces reduction costs. The coking reduction efficiency is significantly improved; the optimized granulation with TFe>77% is further upgraded by gas-coal double-base roasting-grinding selection, and the quality of the obtained reduced iron powder is improved by TFe>95.5% and the product quality is stable. |
