摘要： Systems and methods for monitoring a heat treating atmosphere derive from at least one sensor placed in situ in the atmosphere a process variable, which is indicative of the ratio of gaseous hydrogen H2 (g) to water vapor H2O (g) in the atmosphere. The systems and methods use the process variable, e.g., to control the atmosphere, or to record or display the process variable.

摘要： 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.

摘要： Systems and methods monitor the activity of carbon in a heat treating atmosphere, e.g., where a two phase region is desired for spherodize annealing. The systems and methods generate a computed activity of carbon value for the gas atmosphere as a function of temperature, partial pressure of oxygen, and carbon monoxide content of the gas atmosphere, and without determining a carbon dioxide content of the gas atmosphere. The systems and methods can make use of the computed activity of carbon value, e.g., to control the gas atmosphere.
