Abstract

PURPOSE:To apply a testing load to a test piece accurately, by dividing the core tube of a heating furnace into two parts in the axial direction, connecting the divided ends so that they are separated, and centering loading rods accurately. CONSTITUTION:A test piece 1 comprising ceramics is enclosed in the core tube 3 of a heating furnace 2. The core tube 3 is divided into two upper and lower parts 3H and 3L. The divided ends are connected at tapered surfaces 10H and 10L so that they can be separated. The inside of the core tube 3 is evacuated by a vacuum exhaust pipe 9 so as to obtain a vacuum state. The test piece 1 is heated by a heating furnace 2. Then a bending load is applied by jigs 11H and 11L of loading rods 4H and 4L, and the test is performed. Since the core tube 3 can be divided, the loading rods can be made shorter than the conventional rods. The rods can be centered to the test piece accurately, and the testing load can be applied accurately.

At the same time, by applying a test load to the test piece using the jig of each load rod, the test piece can be subjected to a high temperature atmosphere material test in a vacuum atmosphere. Furthermore, if an inert gas is introduced into the furnace core tube of the heating furnace to create an inert gas atmosphere, the test piece can be subjected to a high-temperature atmosphere material test in the inert gas atmosphere.

Conventionally, in this type of testing device, an integrated furnace core tube that is longer than the heating furnace has been used, and both ends of the furnace core tube have been made to protrude outside the heating furnace. Then, both ends of the furnace core tube were sealed with a sealing material, and both ends of the furnace core tube were cooled with water so that the sealing shrine would not be heated. Therefore, when replacing the specimen and fixture after the test, the furnace core tube must be moved axially along the load rod, and the load rod must be moved axially along the load rod to expose the fixture and specimen of the load lot to the outside. It needed to be even longer than the core tube. For this reason, there was a problem in that the load rod could not be accurately centered and a test load could not be applied accurately to the test piece. When applying a test load to a test piece, there was also a risk that the load rod would buckle due to the test load.

(3) In an apparatus in which a test piece is housed in a furnace core tube of a heating furnace, a test atmosphere such as a vacuum atmosphere is created in the furnace core tube, and the test piece is subjected to a high temperature atmosphere material test,
The furnace core tube of the heating furnace is divided into two parts in the axial direction, and among these two parts, an outwardly facing tapered surface is formed at the divided end of one part, and an inwardly facing tapered surface is formed at the divided end of the other part. A tapered surface is formed, and an intervening member is interposed between the tapered surfaces of each of the parts, thereby separably connecting the divided ends of each of the parts, and the intervening member is molded from a material with a high coefficient of thermal expansion. A high-temperature atmosphere material testing device, characterized in that the divided ends of each of the parts are sealed by thermal expansion.
