Apparatus for melting aluminum alloy scraps

Abstract

Disclosed is a process for melting aluminum alloy scraps which comprises the steps of: giving a rotation force to molten metal reserved in a cylindrical chamber so that the molten metal is made swollen up along the inner circumferential surface of the cylindrical chamber by a centrifugal force caused by the rotation force while the liquid-phase surface of the molten metal is kept so as to draw a parabola to thereby produce a vortex flow in the molten metal; and introducing aluminum alloy scraps into the vortex flow. Further disclosed is an apparatus for melting aluminum alloy scraps which comprises: a furnace body; a melt-material introduction portion having a cylindrical shape and being provided in the furnace body so as to communicate with the furnace body so that molten metal in the furnace body circulates to flow into the melt-material introduction portion; and a moving magnetic field generator provided along the outer wall of the melt-material introduction portion so as to cover the outer wall of the melt-material introduction portion.
