Add In-Process Metal Loss to the Discussion of Surcharges
Surcharges were discussed in the article “What’s in a
Surcharge?” (March/April, p. 27) as a way to cost castings produced with volatile alloy and scrap prices. One important factor left out was in-process metal loss (IML). How many pounds of metal do you buy when your metal-
caster sells you a 100-lb. casting? The obvious answer would be 100 lbs. But the metalcasting process consumes metal in producing the casting. IML is the metal lost that cannot be re-melted for a casting in another heat. IML runs from 13 to 200%. The weight sold should equal the finished casting weight plus the IML weight. IML occurs in melting, cut-off and grinding. Metal is lost during the melt process in five ways: 1. Oxidation—Some oxides form and are included in slag. It is not uncommon to lose about 7% of the chromium contained in an initial charge.
2. Slag Entrainment—Good metal can be included when slag is removed.
