To provide a combination melting system which can melt different types of alloys, attain melting of various types of metals in small lots, a stable and continuous supply of a comparatively large amount of molten metal and supply of a high quality molten metal.

The combination melting system is constituted of a continuous melting/holding furnace equipped with a melting chamber, a holding chamber and a turntable having a plurality of processing furnaces mounted thereon and equipped with a single or a plurality of die-casting stations, wherein the continuous melting/holding furnace is equipped with a tilting means and a discharge port, which can discharge all of the molten metal inside the furnace by their inclination.
