Abstract
A molten lead alloy is supplied from a melting furnace to a casting machine through a feed pipe having a pair of ends connected with the furnace and the machine, respectively, and an intermediate portion situated at a level which is higher than the higher of the two levels of the molten alloy located adjacent to the ends, respectively, of the feed pipe by a distance exceeding the height of a column of the molten alloy which atmospheric pressure can support. An apparatus for supplying the molten alloy in such a way is also disclosed.
