| Abstract |
Smelting reduction technique was applied for the recovery of valuable metals such as V and Cr from LD slag using a Tamman furnace. In the present study, the parameters to increase the reduction rate and efficiency were selected by changing the slag additives, basicity, temperature and amount of reductant. The optimum basicity was found to be 1.4 and maximum reduction of V was reached to less than 0.02% V in the slag in 30 min. The temperature dependence of reduction rate calculated from the experimental data. was 0.0012∼0.0021kg/㎡·s. Metallization degree of slag was 58% (1400℃), 70%(1500℃), 74%(1550℃), 82%(1600℃) and 98%(1600℃, 30min). |
