A high-temperature heating device based on a three-combination reflector

Abstract

The invention discloses a high-temperature heating device based on three combination reflectors, which includes several heating units. The heating unit includes a trough-shaped combined reflector and a heating lamp installed in the trough-shaped combined reflector. An elliptical arc reflector, two circular arc reflectors extending from both ends of the first elliptical arc reflector and two second elliptical arc reflectors, the first elliptical arc reflector and the two second elliptical arc reflectors Both the first focal point and the second focal point coincide, and each second elliptical arc reflector extends from the end of the arc reflector away from the first elliptical arc reflector, and the heating lamp is located at the first focal point and between the two arc reflectors. at the center of the circle. The first elliptical arc reflector and the second elliptical arc reflector focus the light in the direction of large emission angle and small emission angle of the heating lamp onto the sample in turn; the circular arc reflector reflects the light of medium emission angle through the first focal point to the second An elliptical arc surface is finally focused on the sample; this structure is more conducive to concentrating light to increase 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...

Problems solved by technology

[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
