For charging casting machines with non-ferrous molten metals, melt (S) is supplied from a withdrawal chamber (6) of a melting furnace (1) having a gas atmosphere to the filling hole (18) of a casting machine. To achieve an economic, easily dosable charging of the melt, the metered melt (S) is pumped up inside the withdrawal chamer (6) via a metering pump (12) and is drained towards the filling hole (18) via a discharge pipe (15) extending through the furnace wall, where through inlet nozzles (11) opening into the withdrawal chamber (6) a pulsed supply of gas to the withdrawal chamber (6) is effected to support the melt flow.
