ABSTRACT:
Disclosed is a removal unit for removing metallic alien materials, which is adapted to remove metallic alien materials such as metal fragments contained in powder or liquid raw materials. The removal unit includes an outer plate, an inner plate spaced apart from the outer plate, and magnet members coupled between the inner and outer plates. Each magnet member 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, 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. A removal member is 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.
