| titleOfInvention | Constant-Load Creep Test Apparatus for Helium Atmosphere |
| abstract | The present invention relates to a creep test apparatus for evaluating the effect of long-term creep damage by imposing a constant load at the same helium atmosphere and operating temperature on a high temperature structure used in a hydrogen-producing ultra-high temperature gas furnace. It is composed of a movable structure in which the quartz tube and the electric furnace for heating are integrated, so that the specimen can be easily attached and detached to the pull rod, and the metal bellows that can accommodate the micro deformation of the specimen by elastic deformation is the quartz tube and the pull rod. It is provided between and prevents the fluctuation of the load that can be applied to the test piece, and it is composed of a structure that can efficiently cool both ends of the structurally fragile quartz tube can prevent the quartz tube from being damaged by the thermal stress caused by high temperature heating. A constant-load creep test apparatus for helium atmospheres.n n n According to the present invention, there is provided a constant-load creep test apparatus for a helium atmosphere, comprising: a pull rod having a test piece holder for fixing a test piece at a central portion thereof; A quartz tube (20) provided to penetrate the pull rod (100) therein and provided with a shielding plate (95) so as to be positioned above and below the center; An electric furnace configured to be integrally coupled with the quartz tube around an outer wall of the quartz tube; Electric furnace moving means for moving the electric furnace up and down; A load device connected to the pull rod to apply a load to a test piece fixed to a test piece holder of the pull rod; A load cell connected in series with the pull rod to sense a load applied to the test piece from the load device; A microdisplacement detector for detecting a micro displacement of the pull rod according to the creep behavior of a test piece; A gas supply device for injecting helium gas into the quartz tube; And a controller for controlling each device constituting the creep test device.n n n n Ultra High Temperature Gas Furnace, Creep Test, Helium Atmosphere, Electric Furnace, Quartz Tube, Portable, Cooling |
