摘要
研究了冶金过程中一些常见渣在不同温度和加入不同粒度的添加物(煤、焦炭、石墨、 Ca O)条件下,发泡层高度和吹气量的关系。试验得出下述结论: Fruehan 给出的泡沫化指数只适用于外生气源 时温度较高的情况,对温度较低或加入添加物时不适用;较大颗粒的含碳物质能抑制发泡;而细粉状的含碳物质促进发泡;氧化钙粉剂会促进熔渣发泡,发泡的程度与原熔渣的碱度有关。
The relationship between the height of foaming slag and external gas flow rate at different temperature and with additives such like coal,coke or CaO was investigated It was shown by the experimental results that the Fruehans foam index Σ could be used only at high temperature with external source and without additives It was found also that the large carbonaceous particles could reduce the height of foaming slag,however the fine car bonaceous and CaO powder could increase it The basicity of the slag affects the height of foaming slag in case of CaO powder addition
