METHOD OF FERROUS POWDERS PRODUCTION FROM FINE LOOSE POWDERED IRON TRIOXIDE |
| 摘要 |
To manufacture iron powders suitable for powder metallurgy from fine iron oxide powder with an average grain size of less than 100 mu m, the reduction of fine, loose iron oxide powders porous in themselves with a bulk density of less than 1.0 Mg.m<-><3> is carried out with gaseous reduction agents, preferably hydrogen, at temperatures between 1200 and 1392 DEG C, preferably between 1200 and 1300 DEG C. |
