Abstract

A filter element for molten metal, particularly iron or alloy steel, comprises an elongated plate, of foamed ceramic material, with at least one edge of the plan face being rounded e.g. the flow face of the filters may be oval or elliptical. An independent claim is included for filtering molten iron or steel.
