ABSTRACT:
A disposable bed filter for removing particulate matter and/or reducing oxygen in a poured metal melt is located within a trough. The bed filter preferably comprises discrete layers of bed media located in a trough between entry and exit baffle plates. The layers of bed media include a layer of coarse media and a layer of fine media. The trough is preferably provided with a closeable lid to permit removal of the bed media and to compensate for buoyancy of the bed media if present. In its preferred use, the bed filter forms part of a process for making a metal alloy wherein the bed filter simultaneously reduces the oxygen content of the melt and filters particulate matter from the melt.
