| Abstract: | The mineral structure of stainless steel dust was analyzed and the thermodynamic calculation of the oxides in dust was given. A set of spiral sealed reactor was designed in order to study the influences of reaction time and temperature on reduction rate The results showed that the reduction rate increased from 39. 36% to 64. 30% with the increasing temperature when the temperature was 500 -700℃ and the reaction time was up to 300 s. |
