ABSTRACT:
A system for heat treating a metal product has an annealing zone having a first preselected atmosphere condition, a cooling zone having a second preselected atmosphere condition different than the first preselected atmosphere condition, and a blueing zone having a third preselected atmosphere condition different than the first and second preselected atmosphere conditions. A graphical user interface allows an operator select one of the zones for displaying processing information pertaining to the selected zone. The processing information includes a computed ratio of gaseous hydrogen H2(g) to water vapor H2O (g) for the respective preselected atmosphere condition. The graphical user interface allows an operator to control the respective preselected atmosphere based, at least in part, upon the computed ratio.
