Alumina ceramic plates is a special corundum ceramic which is made of AL2O3 as the main raw material and rare metal oxide as flux and calcined by high temperature of one thousand seven hundred degrees.
High alumina content, compact structure and special properties, so it is called special ceramics. The Al2O3. ceramic material is a close-packed hexagonal structure composed of oxygen ions, and the aluminum ions are filled in two-thirds of the octahedral gap, which is the same stable α-Al2O3 structure as natural corundum, so the ceramic has a high melting point and high Hardness and excellent wear resistance. Ceramic patch hardness ≥ HRA85, second only to the hardness of diamond, and the surface smooth friction coefficient is small, the wear resistance is very good, especially in high temperature oxidizing medium or corrosive medium, the performance of ceramic patch material compared with other metal materials More superior.
Performance Characteristics:
1.High hardness
It has been determined by the Shanghai Institute of Ceramics of the Chinese Academy of Sciences to have a Rockwell hardness of HRA80-90, which is second only to diamond, far exceeding the wear resistance of wear-resistant steel and stainless steel.
2. Excellent wear resistance
According to the Institute of Powder Metallurgy of Central South University of Technology, its wear resistance is equivalent to 266 times that of manganese steel and 171.5 times that of high chromium cast iron. According to our customer tracking survey for more than ten years, we can extend the service life of the equipment by at least ten times under the same working conditions.
3. Light weight
Its density is 3.5g/cm3, which is only half of steel, which can greatly reduce the equipment load.
4. Wide range of applications
Any coal-fired, steel, mining, machinery, coal, mining, chemical, cement, port and other enterprises that transport coal, conveying systems, milling systems, ash discharge, dust removal systems, etc. Different types of products are selected for different needs.
