The aim of this work was to study the effects of sound frequency, sound intensity and viscosity of slag on the slag foaming rate and the steady-state foam height. Experiments were carried out using two slags (BaO-B2O3) melted at a temperature of 1223 or 1273 K, as well as water-glycerin solutions at room temperature. Low frequency sound waves (< 1.3 kHz) are found to be more effective in the slag foaming suppression than high frequency waves (1.3-12 kHz). The steady-state foam height decreases abruptly when the sound pressure reaches a threshold value that depends on sound frequency and liquid viscosity. The results can be explained in terms of enhancing the rates of liquid drainage and film rupture induced by sound.
这项工作的目的是研究声频、声强和炉渣粘度对炉渣发泡速率和稳态泡沫高度的影响。实验使用了在1223K或1273K温度下熔化的两种炉渣（BaO-B2O3）以及室温下的水-甘油溶液进行。结果发现，低频声波（<1.3kHz）比高频声波（1.3-12kHz）在抑制炉渣发泡方面更有效。当声压达到取决于声频和液体粘度的阈值时，稳态泡沫高度会突然降低。这些结果可以通过提高由声音引起的液体排水和液膜破裂速率来解释。
