High-temperature heating device based on triple combined reflection cover

Abstract

The invention discloses a high-temperature heating device based on a triple combined reflection cover. The device comprises a plurality of heating units, each heating unit comprises a groove-type combined reflection cover and a heating lamp tube installed in the groove-type combined reflection cover, each groove-type combined reflection cover comprises a first elliptical reflection cover, two circular reflection covers respectively extended from two ends of the first elliptical reflection cover and two second elliptical reflection covers, first focusing points and second focusing points of thefirst elliptical reflection cover and the two elliptical reflection covers are all overlapped, each second elliptical reflection cover is extended from one end, far away from the first elliptical reflection cover, of one circular reflection cover, and the heating lamp tubes are located at the first focusing points and the centers of the two circular reflection covers. The first elliptical reflection covers and the second elliptical reflection covers are employed to focus the light of the heating lamp tubes in the large emission angle direction and the small emission angle direction onto the sample; and the circular reflection covers are employed to reflect the light with a middle emission angle to the first elliptical surface through the first focusing points to finally focus the light onthe sample. The structure more facilitates light focusing to improve the heating temperature of the sample.

Description

technical field [0001] The invention relates to the field of neutron scattering experiments, in particular to a high-temperature heating device based on a three-combination reflector. Background technique [0002] With the in-depth research on the microstructure of materials, the neutron scattering method or synchrotron radiation method has been more popularized and applied. Taking the neutron scattering method as an example, the scattering experiments at room temperature and lower heating temperature have already had mature practical experience. In order to more accurately understand the real-time changes in material properties at high temperatures, it is becoming more and more urgent to design a high-temperature heating furnace. . According to the official websites of the world's four major hash neutron sources and public information, in the high-temperature in-situ experiments of engineering samples, coil induction heating and infrared heating are usually used. The induc...

[0003] The infrared heating method usually uses a halogen tungsten lamp as the light source. In order to improve the heating effect, it is equipped with a reflector to focus the light on the sample. At present, the maximum heating temperature of engineering samples that can be achieved is about 1000°C. Some neutron scattering in-situ experimental heating furnaces cannot meet the requirements, and a higher temperature heating furnace needs to be designed
