FIELD: continuous casting of metals, namely steel, particularly methods of starting metal continuous casting beginning from position when casting plant is prepared for receiving melt metal from transporting vessel such as ladle of steel-melting shop. SUBSTANCE: method comprises steps of determining (before starting casting process) inlet position 31 of power cylinder for controlling stopper that rests by gravity on its seat; after filling intermediate ladle with such stopper, providing operation of power cylinder in order to move it in position 33 for controlled supersealed closing; in order to start casting, moving power cylinder in accordance with predetermined motion law 34 depending of time; determining time moment t1 of starting casting process at using above mentioned law and going on operation of control power cylinder in opening direction in order to provide possibility for metal flowing into mold. EFFECT: possibility for accurate detection of time moment of starting real casting and time moment of beginning casting at filling mold. 5 cl, 2 dwg
