A metal melting furnace which can more effectively melt the melting material and hold the temperature of the molten material so as reduce the fuel economy compared with the past, that is, a metal melting furnace which has a material charging port and a flue at its top and is provided with a melting chamber which is provided with a heating plate which melts a melting material which is charged from the material charging port at its bottom, wherein a heating burner is disposed at a bottom side of the heating plate of the melting chamber, the heating burner is used to melt the melting material on the heating plate, and exhaust gas of the heating burner which circulates through the exhaust gas channel is used to preheat the melting material of the flue and in that at a bottom side of the heating burner of the melting chamber, a molten material holding section to which molten material which was melted on the heating plate flows down into to be stored is formed, and the heating burner is used to hold the temperature of the molten material. |
