Optimizing Steel Mill Lining Boards: ZTA Combining with 95% Alumina Wear-Resistant Ceramics

Steel mill lining boards play a critical role in intercepting and obstructing materials within the mill. However, during the process of intercepting materials, these boards undergo continuous erosion and impact, leading to significant wear and tear. Hence, selecting appropriate lining board materials and installation methods is crucial for their wear resistance and long-term stability.

1. Material Selection for Enhanced Wear Resistance

When choosing lining boards, wear resistance stands as a pivotal consideration. The wear resistance predominantly hinges on the material hardness of the lining boards. The wear-resistant ceramics produced by Sanxin Materials employ premium-grade alumina powder, undergoing intricate processes such as isostatic pressing and high-temperature sintering. With a hardness reaching HRA88, these high-hardness alumina ceramics effectively resist sustained erosion and impact from materials, significantly enhancing the wear resistance of the lining boards.

   2. Impact Resistance and Material Durability

Moreover, while wear-resistant ceramics boast high hardness and excellent wear resistance, their impact resistance tends to be relatively weak. However, Sanxin Materials' ZTA wear-resistant ceramics, incorporating a certain proportion of zirconia oxide and other special elements into alumina, notably enhance the ceramic's toughness, augmenting its impact resistance. This impact resistance adequately meets the steel mill's demands for withstanding impacts.

Endurance in High-Temperature Environments

Furthermore, steel mill environments often involve high temperatures. Therefore, the lining boards must exhibit outstanding heat resistance. While wear-resistant ceramics inherently possess excellent heat resistance, special attention is required during installation. Conventional ceramic adhesives might lose their adhesive properties or reduce their effectiveness at higher temperatures. Hence, during the installation of wear-resistant ceramics, it's advisable to avoid adhesive methods and instead opt for high-temperature-resistant dovetail groove installation.

  3. Comprehensive Solution for Steel Mill Lining Boards

Considering these factors, Sanxin Materials has developed a wear-resistant solution tailored for steel mill lining boards. This solution employs a combination of two wear-resistant ceramics: ZTA wear-resistant ceramics for areas subjected to higher impact forces beneath the lining board, and 95% alumina wear-resistant ceramics for areas facing lesser impact. This combination not only meets the requirements of the lining boards but also effectively reduces costs. Additionally, the utilization of dovetail groove installation ensures the stable operation of the lining boards in high-temperature environments. This solution has been successfully implemented in numerous steel mills, garnering widespread recognition and high praise from customers.
