DISPENSING APPARATUS AND METHOD

摘要

An apparatus for dispensing a molten material from a reservoir of molten material (102) includes a dispensing chamber (100) in communication with the reservoir (102) and a first valve (104) adapted to regulate communication of the dispensing chamber (100) with the reservoir (102). A riser (106) communicates with the dispensing chamber (100) for dispensing the molten material, and a second valve (108) is adapted to regulate communication of the riser (106) with the dispensing chamber (100). Also disclosed is a method for reducing the inclusion of oxides in a casting of a molten metal.
