摘要

本文介绍了用于高温脉冲装置考伯加热器的高级和超级耐火材料的研究结果。研究表明，刚玉耐火材料在 1750 - 1800°C 温度下的长期运行（最长 1.5 年）对材料的热物理性能影响不大。针对不同的层数和温度，对考伯加热器的填料和衬里元件的材料和设计进行了选择。确定气体流速，以确保球填料床的固定位置。高效的填料设计改善了传热效果，并将 Cowper 尺寸缩小了 3.75 倍。

Refractory Materials for High-Temperature Pulsed Installations

The results of studies into high and super refractory materials for use in the Cowper heaters of high-temperature pulsed installations are presented. It is shown that long-term operation of corundum refractories (up to 1.5 years) at temperatures of 1750 – 1800°C has an insignificant effect on the thermophysical properties of the material. The materials and designs of the packing and lining elements of Cowper heaters for different layers and temperatures are selected. The gas flow velocity, which ensures a fixed position of the ball packed bed, is determined. The efficient packing design improves heat transfer and reduces the Cowper dimensions by a factor of 3.75.
