Abstract

The invention discloses a high temperature heating furnace device for testing of high temperature mechanical properties of a material. A high temperature furnace comprises a lower furnace body and anupper furnace body, and further comprises a pair of ceramic linings. The ceramic linings are symmetrical in the up-and-down direction. One ceramic lining is pressed into the lower furnace body, and alower furnace heating component is fixedly installed in the lower furnace body, so that a lower furnace is formed. The other ceramic lining is pressed into the upper furnace body, and an upper furnaceheating component is fixedly installed in the upper furnace body, so that an upper furnace is formed. A lower furnace junction box and the lower furnace are connected, so that a lower furnace assembly is formed. An upper furnace junction box and the upper furnace are connected, so that an upper furnace assembly is formed. The upper furnace assembly and the lower furnace assembly are combined in an opening-to-opening mode. Thermocouples are installed on a thermocouple support and installed on the center line of a combustion chamber. The upper furnace heating component is connected with a temperature controller through the upper furnace junction box, and the lower furnace heating component is connected with the temperature controller through the lower furnace junction box. By the adoption of the high temperature heating furnace device, the temperature can be increased to 1200 DEG C according to the heating rate, and the high temperature heating furnace device is suitable for the constitutive relation, creep deformation and fatigue experiment research under the external load conditions of pull, press, bending and the like.

Description

technical field [0001] The invention relates to the technical field of heating furnaces, in particular to a high-temperature heating furnace device for testing high-temperature mechanical properties of materials. Background technique [0002] New high-temperature materials, especially ceramic matrix composites, have the characteristics of high melting point, high hardness, high strength, large elastic modulus, high chemical stability, high temperature resistance, oxidation resistance, corrosion resistance, wear resistance, and low density, and have been widely used It is used on fairings of rockets and missiles, wear-resistant coatings of aero-engines and high-temperature structural parts of nuclear reactors. The testing and characterization of the mechanical properties of materials is a necessary condition for structural design optimization and strength verification. In order to further expand the application of high-temperature structural material systems, especially cera...
