The invention provides an
energy method-based high-temperature
radiation rate measuring device of a semi-transparent material and a revising method for deducting
background radiation, relating to a high-
temperature normal spectral radiation rate revising and testing method of the semi-transparent material and belonging to the technical field of high-temperature material
physical property measurement. The
energy method-based high-temperature
radiation rate measuring device of the semi-transparent material and the revising method for deducting the
background radiation solve the problems of high construction cost, low temperature heating upper limit and lower testing precision of the traditional test
system. The high-temperature
radiation rate measuring device comprises a Fourier
infrared spectrum analyzer, a reference blackbody furnace, a rotatable reflection mirror, a
heating furnace, a heater, a temperature collecting device, a temperature routing inspection operation instrument, an incidence
light source, a
data processing system, a diaphragm and a semi-transparent test piece; the
heating furnace is internally provided with a light-transmitting opening, a fixing device of the semi-transparent test piece, and the temperature collecting device; the central axis of a light-emitting opening of the incidence
light source, the central axis of the light-transmitting opening of the
heating furnace, the mirror surface of the rotatable reflection mirror and the central axis of the light outlet opening of the reference blackbody furnace are collinear with a
horizontal axis. The
energy method-based high-temperature radiation rate measuring device of the semi-transparent material and the revising method for deducting the
background radiation, disclosed by the invention, are used for measuring the high-temperature spectral normal radiation rate of the surface of the semi-transparent material.
