ABSTRACT:
Apparatus for desulfurizing and heating molten metal includes a refractory body having an open top receptacle, an outlet and a passageway communicating the receptacle with the outlet. An electric coil is disposed in surrounding relation to the receptacle. The upper end of the coil is disposed generally equal to the level of the molten metal in the receptacle. The molten metal is supplied to the receptacle through a first feed member, and a desulfurizing agent is supplied to the receptacle through a second feed member. Upon excitation of the coil, electric currents are induced in the molten metal to heat it and also to agitate it to mix the desulfurizing agent with the molten metal.
