What is Wear-resistant alumina ceramic lining? The wear-resistant alumina ceramic lining is a special corundum ceramic formed by Al2O3 as a main raw material and a rare metal oxide as a solvent and calcined at a high temperature of 1700 degC.
There are many types of wear-resistant alumina ceramic linings, such as alumina ceramic sheets, high-aluminum linings, wear-resistant ceramic linings, alumina ceramic patches, and alumina linings.

What are the characteristics and advantages of wear-resistant alumina ceramic linings?
Wear-resistant alumina ceramic lining features: first of all, the hardness is high, its Rockwell hardness can reach HRA80-90; its wear resistance is excellent, wear resistance can be higher than manganese steel and high chromium cast iron, can make the service life of equipment It is more than ten times longer; the wear-resistant alumina ceramic lining is very light, and its density is 3.65g/cm, which can greatly reduce the load of the equipment; the wear-resistant alumina ceramic lining is firmly bonded and heat-resistant on the equipment. Good performance, can run for a long time at 350 deg C without aging.
Advantages of wear-resistant alumina ceramic lining: wear-resistant alumina ceramic lining is inorganic non-metallic material, so it will not cause pollution to the environment; wear-resistant alumina ceramic lining has good toughness and seismic performance, and has strong fracture toughness. It can effectively prevent breakage and peeling caused by impact force; wear-resistant alumina ceramic lining also has high mechanical strength and good compatibility and integrity.

How to identify wear-resistant alumina ceramic linings?
The first is to look at the surface of the ceramic sheet. The surface of the good wear-resistant alumina ceramic sheet is smooth and not rough, no black spots, uniform color. In addition to vulcanization, the wear-resistant ceramic lining will be attached to a background paper. The joints are continuously formed into a straight line; they can be identified by measuring the density. The alumina content can be calculated by measuring the density; it can also be used for the wear-resistance test, using a sand blasting machine at a pressure of 4.0 kg/cm3, a distance of 50 mm, and a spray angle of 45. Degree, time measured wear within 60 minutes.

Can wear-resistant alumina ceramic linings be used in those industries?
Wear-resistant alumina ceramic linings can be used in the fields of power, metallurgy, coal, petroleum, cement, chemical, machinery and other industries (such as ash, coal, mineral powder, tailings, cement, etc.) The ideal material is safe and reliable for use in high temperature corrosion, high temperature wear or high temperature ablation. The data show that the life of wear-resistant ceramics is ten to twenty times higher than that of cast stone, wear-resistant alloy cast steel, steel-plastic, steel and rubber.
