A Critical Overview of Liquid Metal Processing in the Foundry

Abstract

A need for understanding surrounds many aspects of foundry processing of liquid metals. Without this information it has been difficult to optimize foundry processes. This overview of foundry processing, from melting to casting, attempts to highlight areas that would particularly benefit from improved understanding. In some cases general approaches to the acquisition of needed information are suggested in other areas only the need is stated.

Major emphasis was placed on examining the inefficiencies in cupola melting; tramp element removal (ferrous and nonferrous) and the particular need for generic methods; the origins of gas defects and possible approaches for prevention; the generation and removal of solid inclusions; and finally, the development of sensors for process control and quality assurance.
