摘要
在超高温真空(充气)材料试验装置的加热方式中,目前广泛使用的是辐射加热。传统辐射加热设备受金属发热体的约束,加热温度很难超过2200℃。虽然感应加热和通电加热在超高温加热中得到广泛应用,但其对试样加热的均匀性较差。本文研究了超高温辐射加热石墨发热体的特性,在传统金属发热体试验数据的基础上,采用软件对数据进行分析和推算,选择合适的发热体功率,并在后续试验中进行了验证。
Radiation heating is widely used in the heating methods of ultra-high temperature vacuum(gas-protecting)material testing device.The traditional radiation heating equipment is restricted by the metal heaters,and the heating temperature is difficult to exceed 2200℃.Although induction heating and electric heating are widely used in ultra-high temperature heating,their heating uniformity for sample is poor.In this paper,the characteristics of ultra-high temperature radiation heating graphite heater are studied.Based on the test data of traditional metal heater,the data are analyzed and calculated by using software,and the appropriate heater power is selected,which is verified in subsequent tests.
