The invention provides an arrangement (30) simultaneously pouring first and second mould cavities (211, 222) in a mould sting (14). The arrangement (30) comprises a source of molten metal (40) for delivering a primary stream of molten metal (4'), and a rocker body (60) arranged so as to receive the primary stream of molten metal (4') from the source of molten metal (40). The rocker body (60) comprises an curved surface (62) for receiving the primary stream of molten metal (4') and dividing the primary stream of molten meta! (4') into first and second secondary streams of molten metal (4", 4"") flowing towards opposite first and second end portions (64, 66) of the curved surface (62). The first and second secondary streams of molten metal (4", 4"') pour from the first and second end portions (64, 66) Into the first and second moulds cavities (211, 222). The rocker body (60) is further pivotable around a pivot axis (80), and the position of the pivot axis in relation to the curved surface (62) and/or the shape of the curved surface (62) are adapted such that pivoting of the rocker body (60) affects the ratio between the flow rates (kg/s) of the first secondary stream of molten metal (4") and the second secondary stream of molten metal (4"'). The invention thereby provides an arrangement (30) for simultaneously pouring first and second mould cavities (211, 222) from a single source of molten metal, which arrangement is simple and of low complexity. The rocker body (60) may easily be exchanged or adjusted for different moulds thicknesses and flow rates. Preferably the arrangement (30) comprises a control system (90) for controlling the pouring by pivoting the rocker body (60), and for controlling the flow rate in the primary stream of molten metal (4'). A method for simultaneously pouring first and second mould cavities (211, 222) using the arrangement (30) is also provided. |
