摘要

摘要: 為提高鋼的潔凈度,減少鋼中夾雜物含量,采用超聲波工具頭直接插入高溫鋼液進行處理的方法,對比研究了超聲波處理和吹氬處理去除鋼液中夾雜物的效果.結果表明:超聲波單獨處理可以減少鋼液中Al₂O₃夾雜物,但去除率較低,約為4%～12%;隨著超聲處理時間的增加和超聲波功率的減小,夾雜物去除率提高.吹氬單獨處理時,鋼液中夾雜物去除率較高,為29%～41%;隨氬氣流量的增加,夾雜物去除率呈升高的趨勢.

Abstract: Ultrasonic treatment was used by way of an ultrasonic wave probe directly inserted into molten steel to improve the cleanliness of steel and decrease the amount of inclusions in steel. A comparative study of ultrasonic and argon-blowing treatment was carried out on inclusion removal efficiency in molten steel. Experimental results showed that the amount of inclusions decreased when the ultrasonic wave was inputted into molten steel. But the inclusions removal rate was low, about 4% to 12%. When ultrasonic treatment was carried out solely, with decreasing power and increasing treatment time, the inclusions removal rate was increased. When argon-blowing was carried out solely, the inclusions removal rate was high, from 29% to 41%. With increasing argon-blowing flux, the inclusions removal efficiency was found a trend of rising.
