Claim:
A removal unit for metal alien removal apparatus, having a body into which a raw material containing metallic alien materials are introduced and from which the raw material is discharged, and a removal unit including an outer plate provided with handles, an inner plate spaced apart from the outer plate by a desired distance, and magnet members coupled between the inner plate and the outer plate, so that the metallic alien materials are attached to outer peripheral surfaces of the magnetic members, and then removed, characterized in that each of the magnet members included in the removal unit includes a cylindrical stainless steel rod, a magnet received in the stainless steel rod to extend from one end of the stainless steel rod to at least an intermediate portion of the stainless steel rod, the magnet being coupled to the inner plate, a non-magnetic piece received in the other end of the stainless steel rod and coupled to the outer plate, and a fluorine resin coating formed over an outer peripheral surface of the stainless steel rod; and further having a removal member arranged to be slidable in a longitudinal direction along the magnet members while being in contact with the outer peripheral surfaces of the magnet members, the removal member serving to wipe the metallic alien materials attached to the outer peripheral surface of the stainless steel rod at a portion of the stainless steel rod, in which the magnet is received, toward the end of the stainless steel rod in which the non-magnetic piece is received.
