THE REAL COST OF ALLOYING IN THE CAST HOUSE

摘要

The cost of alloying in the cast house is generally poorly defined, and the process of alloying is not always given the consideration that it should. This paper reviews these issues and gives an insight into the dissolution processes occurring in the furnace. A review is made of why poor elemental recoveries are sometimes observed. Recommendations for best alloying practice are also given. The review concludes that the real cost of alloying is not readily defined. Decisions on which alloying method to adopt therefore require studied consideration.
