FIELD: metallurgy, namely steel casting, possibly movement of melt metal flow between metallurgical reservoirs or casting molds.
SUBSTANCE: casting nozzle included inlet portion designed for engaging with flow rate regulator, for example with stopper. Inlet portion of casting nozzle and flow rate regulator form control zone. Downstream control zone pressure modulator is arranged. Lateral wall and base of modulator form angle Φ being less than 135°. Pressure modulator compresses flow of melt metal downstream control zone and provides lowered pressure drop at flow passing through control zone.
EFFECT: stabilized regulation of metal flow rate, enhanced metal flow control, metal level monitoring in casting mold, reduced erosion of nozzle in control zone.
