熔融还原合成渣中碳还原Fe_2O_3的发泡特性参数

Foam Behavior Parameters for Foaming Caused by Reducing Fe_2O_3 with Graphite in the Synthetic Slag of Smelting Reduction

测定了Ｆｅ２Ｏ３在熔融还原合成渣中被碳还原时，还原气体产生泡沫渣的高度与时间的 关系．由发泡特性参数方程计算了不同条件下的发泡特性参数，从而可以对熔融还原过程中由 内生气源引起的发泡过程进行定量描述。为在铁浴中控制泡沫渣现象提供了必要的基础．

The relationship between the foam height and time has been measured for foaming processes caused by reducing Fe2O3 in smelting reduction synthetic slap. The foam behavior parameters under different condition were determined by means of experimental results and foam behavior equations. In this way, the fo- aming process caused by reducing Fe2O3 in smelting reduction process could be described quantitatively. The results provide necessary basis for controlling the foam phenomenon in iron bath.
