Disclosed is a dosing furnace comprising a rising pipe (3) for delivering metered portions of a molten metal, particularly liquid aluminum alloy. The rising pipe encompasses a throttle section (31) that is located at the inlet end and has an inlet diameter (Di), a diffuser section (32), and a pipe section (33) having an outlet diameter (Do). The transition between the internal surfaces (30) of the throttle section (31), the diffuser section (32), and the pipe section (33) is smooth, without edges being formed. |
