High temperature load soft creep tester test material type

The high temperature load softening creep tester is mainly used to test the deformation performance of materials under high temperature and continuous load. The test material types mainly cover the following categories:

1. Refractory products
Including refractory bricks, castables, refractory prefabricated parts and other shaped refractory materials, used to evaluate their load softening temperature and creep performance under high temperature. This type of material is widely used in high-temperature equipment linings in metallurgy, ceramics, glass and other industries
Typical test standards include: GB/T 5073 (compression creep test), GB/T 5989 (load softening temperature determination), etc.
2. Ceramic materials
For example, precision ceramic parts such as ceramic cores and ceramic shells, test their deformation resistance at high temperatures, commonly used in aerospace and precision casting fields
3. Silicate materials
• Such as cement clinker, silicate glass, etc., need to test their stability under high temperature and high pressure environment
4. Amorphous refractory materials
Including amorphous materials such as refractory mud and spray coatings, it is necessary to evaluate their high-temperature performance after construction through load softening creep test
5. Carbon-containing materials
• For carbon-containing refractory materials (such as magnesia carbon bricks), their high-temperature creep performance needs to be tested under a protective atmosphere to prevent oxidation from interfering with the experimental results
6. Composite materials
For example, metal-based composite materials or high-temperature alloys, some models of high-temperature load softening creep testers can be extended to the performance evaluation of such materials
Standard specimen specifications for test materials

• Common specimen sizes are cylindrical or annular, for example: φ36×50 mm, φ50×50 mm, or φ50×φ12.5×50 mm ring with inner hole
Importance of application areas
By testing the high temperature performance of these materials, industrial kiln design can be optimized, equipment life can be extended, and safety and stability in high temperature environments can be ensured. For example, the load softening temperature of refractory materials directly determines their use limit in high temperature furnaces.
