How Much Do You Know About Wear-resistant Alumina Ceramic Linings
What is Wear-resistant Alumina Ceramic Lining?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 solvant. This ceramic was then calcined in a high heat of 1700°C.
There are various types of alumina tiles that can be used as wear-resistant linings. These include alumina sheets, high aluminum linings (also known as wear-resistant ceramics), alumina patches and alumina linings.
What are some of the benefits and features of ceramic alumina linings that resist wear?
Wear-resistant Alumina Ceramic Lining Features: First, the hardness of the alumina linings is high. Their Rockwell hardness can be as high as HRA80-90. Secondly, their wear resistance is excellent. They can wear more than high-chromium cast-iron and manganese-steel, which makes the equipment service life ten-times longer. Thirdly, they are very light and have a density of 3.65g/cm. This can reduce the weight of the equipment It is a good performer, and can be used for a very long time in temperatures up to 350 deg C.
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 effectively stop breakage and peeling due to impact force.
How can I identify alumina ceramic linings that are resistant to wear?
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 formed in a straight line. They can be identified through measuring the 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-resistant ceramic alumina linings be applied in those industries?
Wear-resistant alumina Ceramic Linings can be applied in many industries, including power, metallurgy (such as coal, mineral, powder, 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 alloys, steel plastic, steel and rubber.
