<p>This invention relates to an apparatus and a method for measuring hot hardness (HIT) of materials. The apparatus comprises a main frame (V) and a displacement gauge (9) connected to the frame (V) by spring elements (12), and the gauge (9) is provided by a core rod (91) biased against the frame (V) by a mounting spring (6). A measuring frame (1) having an inner surface (11) for fixing a test piece (5) is mounted on the frame (V), and a measuring rod (2) is attached to the rod (91). A measuring tip (4) is connected to the measuring rod (2), and a furnace (8) surrounding at least the inner surface (11) is arranged around the measuring frame (1), and a thermocouple (13) for measuring the temperature of the test piece (5) is provided, wherein the measuring rod (2) and the measuring frame (1) are made of the same material.</p> |
