摘要： A setter is configured to minimize distortion of a core supported during firing. The configuration also provides for adequate gas flow both to envelope the core and to provide an aspiration effort to cause the gas to be drawn downwardly through and about the core structure to the interior of the setter to enhance the removal of reaction products therefrom. A retort, preferably made of molybdenum, is provided to enhance the effects of the setter configuration.
摘要翻译： 配置器被配置为使得在点火期间支撑的铁心的失真最小化。 该构造还提供足够的气流以包围芯部并且提供吸气努力以使气体向下通过芯结构并且围绕芯结构向下拉到固定器的内部，以增强从其中除去反应产物。 提供优选由钼制成的蒸馏器以增强固定器构型的效果。
