Title
Effects of Temperature and Carbon Content on the Reduction of Chromium Ore with solid Carbon
조종민Chong Min Cho, 박대규Dae Gyu Park, 이일옥Il Ock Lee
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.
