ABSTRACT:
The invention provides a filter apparatus and method for removing inclusions from a molten metal alloy and includes a container having an inlet portion and an outlet portion. A filter bed is located within said container, interposed between said container inlet and said container outlet, and is comprised of a plurality of filter zones arranged in progressive layers. Each of the filter zones contains particles of filter material within a preselected size range, and the filter zones are successively arranged to selectively locate the largest filter particles at the container outlet and the smallest filter particles at the container inlet. Molten metal alloy is filtered by passing it through the filter bed.
