    摘要: An oxygen probe for measuring the characteristics of furnace gases. The probe includes electrodes of a long lasting and relatively inexpensive nickel containing alloy. The probe is formed with apertures and internal passages for ventilating the three phase contact zones between gas, electrolyte, and electrodes with furnace gases, thereby minimizing errors due to catalytic reactions at the electrodes. The probe sheath may be composed of the same alloy as the electrodes, and the electrodes may be fabricated as an integral part of the sheath, so that the sheath serves both as a structural member and as an electrical conductor for conducting voltage generated within the electrodes. A gas pump may be used to assure adequate ventilation to the electrode-electrolyte interfaces.

    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.

    摘要: Disclosed herein is a gas sampling system for analyzing the oxygen partial pressure in a gas carburizing atmosphere. The system is appropriate for remote sensing of gas when the probe can't be fitted in the heat treating apparatus. Sooting of the sampled gas tube and probe is eliminated by use of ceramic, non-catalytic surfaces in the measuring vessel. A ceramic feed pipe, with a small diameter, introduces the gas to be measured into the vessel and increases the velocity of the gas to avoid sooting.

    摘要: A probe comprising a tube made of solid electrolyte material is slidably mounted within a ceramic support tube which is mounted to project into the interior of a furnace. The end of the electrolyte tube is closed and the support tube has open ports or windows therein which expose the exterior end surface of the electrolyte tube to the hot furnace gases and causes a voltage to develop between the interior and the exterior surfaces of the electrolyte tube which is indicative of a furnace gas characterstic. A first electrode is supported between the ends of the electrolyte tube and the support tube, and a second electrode is supported within the inner end of the electrolyte tube. To prolong the life of the electrode, it is preferably made either of multiple layers of noble metal wire screens mounted in face-to-face relationship, a chemically stable electronic ceramic conductor such as cation-doped lanthanum chromite, or a noble metal screen coated with an electronic conducting ceramic cement.

    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: A probe comprising a tube made of solid electrolyte material is slidably mounted within a ceramic support tube which is mounted to project into the interior of a furnace. The end of the electrolyte tube is closed and the support tube has open ports or windows therein which expose the exterior end surface of the electrolyte tube to the hot furnace gases and causes a voltage to develop between the interior and the exterior surfaces of the electrolyte tube which is indicative of a furnace gas characteristic. A first electrode is supported between the ends of the electrolyte tube and the support tube, and a second electrode is supported within the inner end of the electrolyte tube. A hollow cylindrical cap is adjustably mounted adjacent the outer end of the electrolyte tube and contains an internal spring which urges the closed end of the electrolyte tube against the first electrode to maintain good electrical contact therebetween in spite of corrosive reaction of the electrode with the hot furnace gases or the electrolyte. To prolong the life of the electrode, it is preferably made either of two noble metal wire screens mounted in face-to-face relationship, or it is made of a chemically stable electronic ceramic conductor such as cation-doped lanthanum chromite, which is substantially inert with respect to known electrolytes and known hot furnace gases.
