ABSTRACT:
An apparatus and method for filtering molten metal are disclosed. The apparatus utilizes a continuous filtering medium that is serially indexed into the metal filtering area. The apparatus may be used to filter ferrous and non-ferrous metals, and provides significant cost and time savings. In one embodiment the apparatus allows automatic indexing of a new filter for each shot or pour on high production casting machines. In another embodiment the apparatus is adapted to filter large amounts of metal up to 5,000 pounds or more.
