Beschreibung
Zusammenfassung:	FIELD: metallurgy, namely metal agitation in steel casting ladles. ^ SUBSTANCE: method comprises steps of blowing steel with gas at least through two blowing tuyeres. Blowing through each tuyere is realized at different intensity changed according to sine law at predetermined amplitude, frequency and phase shift for each blowing tuyere. ^ EFFECT: shortened time period of metal treatment, improved quality of metal, lowered consumption of materials fed to ladle, reduced wear of refractory lining of steel casting ladle. ^ 1 dwg
