Melting and holding furnace for aluminum blocks

A continuous melting apparatus for a low melting point metal is disclosed. The apparatus includes a melting furnace main body (5) forming a combustion chamber (6) surrounded by a refractory lining, a crucible (1) formed with a tapping orifice (2) at an appropriate position of a body and housed at the center portion of said combustion chamber, a burner (8) provided on a side wall portion of said melting furnace main body (5) for heating said crucible (1) in said combustion chamber (6) and a receptacle (6, 13) for receiving a melt flowing out through said tapping orifice (2) of said crucible (1). In the continuous melting apparatus, with employing a melting method of burner heating type which is inexpensive, easy to handle and maintenance, with successfully minimizing oxidation loss which was the shortcoming of the burner type. Also, generation of corundum on the furnace wall surface due to reaction of the aluminum melt and the furnace wall can be successfully avoided.
