Anti-abrasion liners
In various industries such as steel and mines, especially in industries that deal with the processing of raw materials, the issue of abrasion and corrosion of equipment is a major challenge and costly, and repair or replacement of damaged equipment requires stopping the production line and high repair costs. Therefore, from the past until now, the use of protective coatings (in different materials) has been considered as a principled solution by designers. The use of hardened metals, especially anti-abrasion steels, in many cases reduces costs and prolongs stopping intervals. However, in environments that are exposed to moisture, contact with corrosive chemicals, the passage of materials with high hardness, as well as high operating temperatures, the use of hard metals is seriously challenged. But anti-abrasion ceramics, especially ceramics with a high percentage of alumina (AL2O3) due to their unique mechanical properties can be a good alternative to hard metals in these conditions. These characteristics make this type of industrial ceramics widely used in various industries such as steel, iron, mines, cement, powder making, etc.:
- Very high level hardness
- Being amphoteric (neutral) and not reacting with various chemical substances, including alkaline and acidic environments
- Less density than metals, which causes less load on the equipment
- Ability to install easily and with various methods (pasting, welding, bolting)
- No phase change and maintenance of mechanical properties at high temperatures
- Easy and low cost maintenance and maintenance
- Reasonable price
It should be noted that in places where equipment is subject to impact, falling heavy objects, as well as temperature changes with a steep slope and heat shocks, the use of these products should be done with further investigation and consultation with AIC experts.
