FIELD: forming flow of gas introduced into molten metal. SUBSTANCE: proposed device includes injector and casing covering it. Injector has main passage, injection space, nozzle and two secondary passages. Nozzle has inlet hole which is communicated with main passage and outlet hole which is communicated with injection space. First secondary passage is located at radial distance from main passage and is communicated with injection space. Second secondary passage is located at radial distance from first secondary passage and is communicated with injection space. Casing passes beyond outlet hole of nozzle for determination of injection space. At least one additional passage is located in casing whose axis is located at angle relative to axis of main passage. Device has at least two additional passages located in casing which are so constructed that axes of flows of liquids discharged from them may be intersecting or diverging. EFFECT: possibility of maintaining diameter and velocity of jet after injection and penetrating of gas over entire surface of liquid. 9 cl, 5 dwg
