What is Wear resistant alumina ceramic lining (Alumina Ceramic Lining)?<br />
The wear-resistant alumina lining is made from a corundum special ceramic, which is formed using Al2O3 (as the main raw material) and a rare metallic oxide as a solvent. This ceramic was then calcined in high temperatures of 1700°C.<br />
There are many different types of alumina tiles that can be used as wear-resistant ceramic linings. These include alumina sheets, high aluminum linings (also known as wear-resistant ceramics), alumina patches and alumina linings.
What are some of the advantages and characteristics of alumina ceramic linings that resist wear?<br />
Wear-resistant Alumina Ceramic Lining Features: First, the hardness is good, it can reach HRA80 to 90; its wear resistance, wear resistance that can be more than ten-times higher than high-chromium cast-iron and manganese-steel, can extend the service life. The wear-resistant Alumina Ceramic Lining is light and its density of 3.65g/cm can reduce the weight of the equipment. It is a good performer, and can be used for a very long time at 350° C.<br />
Wear-resistant Alumina Ceramic Lining: It is made from non-metallic inorganic material. This means that it won’t pollute the atmosphere. Wear-resistant ceramic lining has high mechanical strength, good compatibility and integrity. It can prevent breakage or peeling due to impact force.
What is the wear resistance of alumina ceramic linings and how can you identify them?<br />
Look at the surface of ceramic sheet first. The surface is smooth without being rough. There are no black spots or irregularities. After vulcanization the ceramic wear-resistant lining is attached to a paper background. The joints will be continuously shaped into a straightline. They can be identified through measuring their density. Density can be measured to calculate the alumina. The test can also be performed using a 45-degree spray angle, a 50-mm distance, and a pressure 4.0 kg/cm3. Gradient, time-measured wear within 60 minute.
Can wear resistance alumina linings be applied in those industries?<br />
Wear-resistant alumina Ceramic Linings can be applied in many industries, including power, metallurgy (such as coal, mineral powders, tailings and cement), chemical, machinery, and others. The material should be safe and reliable to use for high-temperature corrosion, high-temperature wear or high-temperature ablation. The data shows that the wear-resistant materials have a ten-to-twenty-fold higher life span than cast stone or steel-plastic composites, steel, or rubber.<br />
