叙述了熔渣起泡工艺控制的优势和困难,焦点放在热力学模拟在等温溶解图绘制中的作用[示出了碱度系数、温度以及MgO和FeO含量(重量百分比)之间的关系],这些图预测出使熔融渣最上层表面泡沫有较长寿命所需液相的组分变化。为了了解熔渣起泡现象,使用了数学模型并进行了试验性实验,但是没有同时考虑到工艺中所需要的所有变化。在这项研究中,对一些试验性结果和等温溶解图进行了比较。根据计算结果,知道使用热力学模拟是一个很好的选择,在炼钢的一些设备中有助于保持熔渣起泡发生。等温溶解图的使用提供了为得到稳定的泡沫所进行调整的一个清楚图像,从而减少了一些附加实验的分析。
Described the advantages and difficulties of slag blister control, focusing on the role of thermodynamic simulations in isothermal dissolution mapping [shows the relationship between alkalinity coefficient, temperature and MgO and FeO content (weight percent)], These figures predict the compositional changes of the liquid phase required to have a longer life on the surface foam of the molten slag. To understand slag blistering, a mathematical model was used and experimental experiments were conducted, but not all of the changes needed in the process were taken into account. In this study, some experimental results and isothermal dissolution charts were compared. According to the calculations, knowing that the use of thermodynamic simulations is a good choice, it helps to keep blister blisters in some of the steelmaking equipment. The use of an isothermal dissolution map provides a clear picture of the adjustments made to obtain a stable foam, thereby reducing some of the additional experimental analysis.
