| Abstract |
On the development of ferrochrome production process by coal, the chromite pellets with carbon(l0, 15 and 20 wt%) were reduced at the temperature range of 1,200 to 1,400℃ for confirming the effects of temperature and carbon content. The chromite pellets with carbon were rapidly reduced at temperature above 1,100℃, and the reduction rate of the chromite pellets with carbon was increased in proportion to the carbon content and temperature. When the chromite pellets are reduced above 1,350℃, the reduction of MgO in gangue mineral becomes significant. |
