【Abstract】 The properties of high-temperature alloys and high-temperature ceramic protective tube materials and their applications in the reformer were analyzed. The results showed that high temperature protection tube materials such as GH3039, Haynes 214, 3 YC52, MoSi₂ and recrystallized silicon carbide are suitable for the application in the central and lower temperature-measuring points of the reformer. The application of high-purity corundum tube in the upper temperature-measuring point of the reformer greatly improves the service life of the reformer’s high-temperature thermocouples and is an ideal high-temperature protection tube material.更多还原
