Crucible-Type Continuous Melting Furnance

摘要

The present invention provides a crucible-type continuous melting furnace by which the melted amount of the material can be readily controlled. A crucible-type continuous melting furnace 1 includes a preheating tower 31 for storing the material to be melted (a), and an exhaust port 34 on the top thereof; a melting crucible furnace 11 disposed below the preheating tower 31 and having a melting crucible 71 to which the material to be melted (a) is supplied from the preheating tower 31; a heating burner 3 for heating the melting crucible 71; and a preheating burner 4 for preheating the material to be melted and disposed in a position that is higher than the heating burner 3; the melting crucible furnace 11 having an introduction portion for introducing a combustion gas from the heating burner 3 into the preheating tower 31; and the melting crucible 71 having a molten metal outlet 74 on the side wall for discharging the molten metal (b) obtained by melting the material (a).
