Alumina Ceramic Wear Tile

Wear and tear is an industrial nightmare as it impacts the efficiency of the equipment along with raising the maintenance expenses. However, Shandong Qishuai Wear-Resistant Equipment Co., Ltd. brings you an excellent solution in terms of Alumina Ceramic Wear Tilewith its superior quality.

These are produced employing cutting edge methodology of production along with a high quality raw material, which ensures that these Alumina Ceramic Wear Tiledemonstrate remarkable abrasion resistant quality and enhance the service life of equipment.

Product Features:

High Hardness: Aluminium oxide ceramic wear-resistant bricks possess exceptional hardness, achieving a Mohs hardness rating of approximately 9, second only to diamond. This remarkable hardness endows them with wear resistance far surpassing that of conventional materials.Outstanding corrosion resistance: Aluminium oxide ceramic wear-resistant bricks have good resistance to most common chemical media. The ceramic lining remains intact in corrosive media, for example in acidic or basic media.

Exceptional high-temperature stability: Alumina Ceramic Wear Tilecan uphold their properties at high temperatures. The melting point is higher than 2000°C. By using aluminium oxide ceramic wear-resistant bricks the frequency of stoppages and maintenance work for lining material is decreased due to the high operation temperature of the production process (up to 1600°C).

Other characteristics: In addition to the above excellent properties, Alumina Ceramic Wear Tilealso have the following advantages of low thermal expansion coefficient. The Alumina Ceramic Wear Tilecan maintain the size change in the face of large temperature changes, and the phenomenon of cracking due to thermal expansion and contraction.

The following table shows the parameters comparison between Alumina Ceramic Wear Tileand traditional metallic materials.

Production Processes and Quality Assurance

Advanced production processes:

Shandong Qishuai Wear Resistant Equipment Co., Ltd. Ultra Finehas advanced production process, make sure every product attain the expected performance. The rest is just a brief overview of the production process from raw material to the final product.

Selection of Raw Materials: Chose high-purity alumina powder with over 99% purity as the raw material. According to the performance requirement of the products, certain amount of stabilisers, binders and other auxiliary materials are added. The superior raw materials are the basis of the product's high performance.

Uniform Mixing: 

Aluminium oxide powder and other auxiliary materials are mixed in specific proportion in the ball mills and other advanced equipments, so as to ensure the raw materials are evenly mixed and dispersed in all directions, offering good material reserve for the subsequent forming and sintering process.

Forming Process: 

Advanced dry pressing technology is used, which can produce products with higher density and better structure. The mould is selected according to the shape and dimensional requirements of the product. Then the raw material is pressed into shape.

Sintering Treatment: 

It is an important process that puts the formed green bodies into high temperature sintering furnace for sintering. The green bodies put into the furnace are sintered at the temperature of 1600°C-1800°C.Clay particles are fused together and formed into a dense ceramic body. This process greatly improves the hardness and abrasion resistance of the products.

Finishing and Post-Treatment: 

The sintered products are usually subjected to grinding and other finishing processes to ensure the dimensional accuracy of the products. The flatness of the two planes is also ensured by the grinding process. In some special cases, coating process is used to further improve corrosion resistance, oxidation resistance and other performance characteristics.

Rigorous Quality Control:

In order to ensure that all the manufactured alumina ceramic wear resistant bricks can meet quality requirements, we have established strict quality inspection system from raw materials to the final product.

Raw Material Inspection: 

The alumina powder and other raw materials are randomly checked in each production link. The chemical composition of raw materials is analyzed by X-ray fluorescence spectrometer to ensure that the key indexes such as alumina content meet the requirements. Laser particle size analyser is used to check the particle size distribution of powder.

Process Inspection: 

During the production process, density testing is carried out on green bodies formed by dry pressing with electronic densitometer to ensure that the density of each green body is uniform. The hardness of sintered products is also tested with Rockwell hardness tester to ensure that the hardness of the products meets the specified hardness standard.

Finished Product Inspection: 

All kinds of tests are carried out on the final products, including abrasion resistance testing and corrosion resistance testing. The abrasion test machine simulates the abrasion conditions in actual use to test the abrasion resistance of the product. The corrosion resistance of the product is placed in acid, alkali and other corrosive media to observe the degree of corrosion.

We strictly follow the international quality management system standard ISO 9001 quality management system standard and relevant requirements of industry standards. Only products that pass all the inspection links are allowed to enter the market so that our customers can get the stable and high performance of alumina ceramic wear resistant bricks.
