PURPOSE: To correct tendency where molten metal supplying quantity is gradually reduced and to supply a molten metal with high accuracy by starting pressurizing in an air pressure molten metal supplying furnace and supplying the molten metal in a longer time by the time corresponding to the fixed ratio of time until a molten metal supplying sensor arranged at the molten metal supplying tube detects the molten metal. ;CONSTITUTION: The tendency where the holding quantity of the molten metal 2 in the air pressure molten metal supplying furnace 1 is reduced by supplying the molten metal and the molten metal supplying quantity itself is gradually reduced is changed to supply the molten metal in longer time by the time corresponding to the fixed rate of the time until the molten metal 2 where the molten metal sensor 6 arranged at the fixed point of the molten metal discharging hole 5 of the molten metal tube 3 for supplying the molten metal 2 provided on the air pressure molten metal supplying furnace 1 to the outside of the furnace 1 detects the molten metal 2 raising in the molten metal tube 3 every time through the molten meter 3 from the furnace 1 for molten metal.;COPYRIGHT: (C)1993,JPO&Japio
