There are many varieties of high-aluminum bricks on the market, but the quality is almost the same, but the price is uneven. So how to choose a good high aluminum brick? Let's take a look at the high alumina brick manufacturers:
During the use of high-aluminum bricks, it is subjected to physical, chemical, mechanical effects such as high temperature (usually 1000~1800 °C), simple melting and softening, or erosion and erosion, or occurrence of cracking and damage, so that the operation is suspended. And smear the material. Therefore, it is necessary to have high-aluminum bricks having the property of being able to get used to various operating conditions. The quality of high-aluminum bricks depends on their nature. It is a specification for evaluating the quality of the system. In production, it is the basis for formulating and improving the production process, and checking whether the production process is correct and stable. The correct and reasonable selection of high-aluminum bricks is also based on its nature.
Countries have standardized methods for debugging the properties of high-aluminum bricks, such as the TOCT of the former Soviet Union, the ASTM specification of the United States, the BSI approach of the United Kingdom, and the CIN of West Germany and the JIS of Japan. Following the development of scientific skills and the deepening of the knowledge of the high-aluminum brick itself and its damage mechanism, the inspection project has been continuously added, the skills and improvement methods have been continuously modified, and the normative measures have to be revised every certain period.
How to distinguish high alumina bricks has always been a problem in this profession. In recent years, Friends of the high-aluminum brick factory in the high-aluminum brick materials and products inspection methods and skills, although continuous improvement and improvement, because the laboratory test conditions and practical use conditions are not fully compatible, resulting in specific conditions in the laboratory The results of the test below cannot predict the operational function of the high-aluminum brick in practice and infer its service life. However, the current testing methods (in addition to continuous research and improvement) can still be used as a method to determine the quality of high-aluminum bricks. After the test, it is possible to check the quality of the manufactured product and check whether the incoming materials meet the requirements, determine the quality of the material, control the production process, discuss the nature of the products after use, and seek the path of improvement and quality improvement.
The above is a simple introduction of high-aluminum brick manufacturers. Through our introduction, we already know how to distinguish the quality of high-aluminum bricks. For more information about high-aluminum bricks, please continue to pay attention to our official website!
