Industrial-grade Alumina ceramic linings are wear-resistant materials made primarily from alumina using a special process. They are widely used in industry.

Performance

High wear resistance: Alumina ceramic linings have a Mohs hardness of approximately 9, second only to diamond. Their wear resistance is several times, or even dozens of times, higher than that of manganese steel. For example, the wear volume of certain alumina wear-resistant Ceramic Linings is ≤0.03 cm³ (under industry standard testing conditions), effectively resisting erosion and wear from materials.

Excellent chemical stability: Alumina ceramic linings are highly resistant to corrosive media, such as acids and alkalis. They can withstand the erosion of acidic and alkaline solutions in reactors, storage tanks, and other equipment in chemical plants, ensuring the structural integrity of the equipment while preventing product contamination. · Impact Resistance: Some Alumina ceramic liners utilize special formulations, such as the introduction of Cr₂O₃ and TiO₂, which have a similar lattice structure to Al₂O₃, along with the addition of ZnO whiskers. This improves fracture toughness to a value of KIC ≥ 4.8 MPa·m¹/², enabling them to withstand certain impact loads.

· High Temperature Resistance: Alumina ceramic liners can operate stably at temperatures up to 1600°C or even higher, maintaining reliable mechanical properties without softening or deformation, making them suitable for high-temperature industries such as metallurgy.

· Easy Installation: Alumina ceramic liners can be customized to meet equipment requirements, offering flexible sizes and shapes. They can also be combined with other materials, such as steel and rubber, to form composite materials, making them easy to install on the interior and exterior walls of various equipment or within pipelines.

· Common Specifications: Alumina ceramic liners are available in a variety of specifications, classified by alumina content, including 92%, 95%, and 99%. Its shapes include rectangular, trapezoidal, and special shapes, with thicknesses generally ranging from 3 to 50mm. Length and width can be customized according to actual needs.

Applications

Mining Industry: It can be used in crusher hammers and liners, as well as vibrating screens and side panels. It effectively resists the severe impact and abrasion of ore, reducing equipment failure rates and improving production efficiency.

Power Industry: In coal transportation systems for thermal power generation, it can be used as a lining for pipes and chutes, reducing friction and wear between coal and equipment. It also provides wear and high-temperature resistance in boiler burners and flues, ensuring safe and stable operation.

Steel and Metallurgical Industry: It is used in everything from raw material transportation and blast furnace linings in ironmaking to converters and refining furnaces in steelmaking. It protects furnaces from erosion and erosion by high-temperature molten iron and slag, extending the life of the lining and reducing production losses.
