How Much Do You Know About Wear-resistant Alumina Ceramic Linings
What is Wear resistant alumina ceramic lining (Alumina Ceramic Lining)?The wear-resistant alumina lining is made from a corundum special ceramic, which is a mixture of Al2O3 (as the main raw material) and a rare metallic oxide (as a solvent), and then calcined in a high heat of 1700°C.
There are many different 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 is extremely high. Rockwell hardness up to HRA80-90. Second, the wear resistance is excellent. Wear resistance can be more than ten-times higher than high-chromium cast-iron and manganese-steel. Third, the wear resistant alumina lining is light and its density of 3.65g/cm can reduce the weight of the equipment. Fourth, the wear resistant alumina lining adheres firmly and is 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 a high mechanical strength, good compatibility and integrity. It can prevent breaking and peeling due to impact force.
How can I identify wear resistant alumina ceramic linings?
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 these industries?
Wear-resistant alumina linings are used in power, metallurgy (including coal), petroleum, chemical, machinery, and other industries. The material should be safe and reliable to use for high-temperature corrosion, high-temperature wear or high-temperature ablation. Data show that the wear-resistant materials have a ten-to-twenty-fold higher life span than cast stone or steel alloys.
