Calculation of Foam Behavior Parameters in Foaming Prosess Originated from Re-ducing Oxide by Carbon in Melten Slags

分析了高温熔渣中碳还原氧化物的反应和传热机理,确定了还原反应产生气体量和时间的关系,进而给出了相应的内生气源发泡方程.介绍了计算发泡特性参数软件的特点和功能,特别是对确定消泡过程的开始时间进行了详细的讨论.将在10 kg感应炉测定含TiO2渣的实验结果,通过计算程序确定了内生气源引起发泡过程的特性参数.

The mechanism of dynamics and heat transfer of reducing oxides by carbon in molten slags was analyzed and the relationship between the gas quantity of oxide reduction and time was determined. The foaming equations originated from the reaction were established. A software for calculating foam behavior parameters were introduced. Specially, the determination of the beginning time of rupture foam was discussed in detail. By means of the experimental results of reducing TiO2 in an induction furnace (10 kg) in laboratory, the foam behavior parameters originated from the reaction in the molten slags were carried out through the software.
