Molten metal baths react to alloying additions by some temperature loss. It is often advantageous to the melter to be able to calculate that loss to allow for any necessary corrective action.
A frequent question on the foundry floor (and often in the foundry office)is: "How much heat is lost by adding a specific alloy to a metal bath?" Many times it is also desirable to know how many pounds of an alloy or other addition can be made without lowering the temperature of a melt below a certain limit. The answer to either of these questions can be estimated quite readily using the temperature loss formula:
This formula states that the temperature loss can be ...
