Study on the properties of refractories

With the development of science and technology, China's refractory industry has developed rapidly, and the output of refractory materials has ranked first in the world for many years. However, the overall technical level and product structure of the refractory industry are far from the international advanced level. Faced with the rapid development of domestic high-temperature industrial technology and the opportunities and challenges for China's refractory industry after joining the WTO, China's refractory industry will also continue to find a way forward.

 

With the development of high-temperature industry and the promotion of technological progress, people's understanding of the properties of refractories will become deeper and more demanding, and new performance items will continue to express the quality and durability of refractories. Therefore, more and more items are required to measure the performance of refractory materials.

Refractory materials refer to inorganic non-metal materials with a fire resistance of not less than 1580 ° C, good resistance to thermal shock and chemical attack, low thermal conductivity and low expansion coefficient. It includes natural ore and various products made through a certain process according to a certain purpose. At present, refractories generally refer to inorganic non-metallic materials used in the lining of production equipment such as metallurgy, petrochemicals, cement, and ceramics.

 

In the future, the main direction of the development of refractory technology should be to comprehensively improve the quality according to the characteristics of China's raw materials resources, develop high-quality and efficient new products at the end, adopt advanced processes, technological innovations and update equipment to improve the use effect and reduce the consumption and adapt to the harsh high-temperature technology Claim.
