Summary
-
1.
Heating in molten glass has the following advantages: a low degree of decarburization and insignificant losses from oxidation of the metal; good quatily of the surface, which makes it possible to decrease the oversize for further mechanical treatment to the minimum; increase of the strength of the dies; and improvement of the working conditions.
-
2.
Molten glass is a much cheaper heating medium than oxidation-free media.
