ZTA ceramic tiles, as wear-resistant lining, have a service life approximately four times that of original alumina ceramic lining or other materials. The application effect is very good. In the conveying system of the steel industry, dense phase conveying system is usually used, which uses airflow to transport granular materials in closed pipelines. Therefore, the conveying volume is large, the conveying distance is long, and the conveying speed is high. However, there are also serious issues such as pipeline wear, frequent replacement, environmental pollution, and impact on production efficiency. The workers in the steel industry feel deeply uneasy and distressed.

Zirconia and alumina composite lining, with the following characteristics:

1. The toughness of zirconia ceramics, with the hardness, wear resistance, and impact resistance of alumina ceramics;

2. Lightweight, smooth surface, no adhesion, no blockage;

3. Flexible design, size can be designed according to site conditions;

4. Long service life, greatly reducing the number of cylinder liner replacements.
