Product Performance
Overall Performance: The newly developed earth wear-resistant alloy material adopts an advanced EPC lost foam vacuum casting process, which eliminates common casting defects such as porosity, slag inclusions, loose structure, and large deformation. This process ensures a high-quality material composition, similar to FeCr, FeMn, FeMo, Ni, Re, FeSi, and other alloys, while adding iron-based elements such as FeV, FeNb, and Cu. These additions enhance wear and corrosion resistance, mechanical strength, impact resistance, and weldability, making the material ideal for use in power plant coal grinding systems, powder production systems, slag removal systems, coal washing system pipelines, and metallurgical slag handling pipelines.
High Wear Resistance: The rare-earth wear-resistant alloy pipe material offers wear resistance. The incorporation of FeV, FeNb, and Cu further refines the material's microstructure, improving grain density, strength, plasticity, and passivation of the metal matrix. This results in enhanced wear resistance compared to the original alloy material.
High Temperature and Corrosion Resistance: The alloy’s resistance to high temperatures and corrosion is largely influenced by its Ni and Cr content, which determine its heat resistance, and Cr and Cu, which contribute to its corrosion resistance. The combination of these elements significantly improves the material's overall performance, enabling it to withstand challenging operating environments.
Advanced Technology and Stable Performance: The EPC lost foam vacuum casting process ensures high mold precision, uniform material structure, and consistent performance. It is especially effective for producing complex-shaped parts, liners, screen plates, and both square and round joints.
Low Pipeline Running Resistance: Thanks to the refined metallographic structure, the grain size of the casting is much smaller, and the casting process eliminates gas, slag inclusions, and loose structures. Over time, the inner surface of the pipeline becomes as smooth as a mirror, reducing friction and running resistance, which prolongs the service life of the pipeline and further enhances wear resistance.
Easy Installation and Use: The material is compatible with various installation methods, including flange mounting, quick connectors, and direct welding. The addition of FeV, FeNb, and Cu increases the hardness of the material through heat treatment, allowing for easy cutting, replacement, and welding without compromising the integrity of the material.
Working Principle
Abrasive wear is one of the severe forms of material degradation, caused by hard abrasives that cut or scrape the metal surface. These abrasives create plastic deformation and wear marks as they penetrate the metal, eventually causing surface damage. The newly developed high-strength earth wear-resistant material addresses this issue by enhancing the material’s ability to withstand abrasive wear, preventing accidents such as coal leakage, oil leakage, air leakage, and ash leakage in coal crushing, grinding, and powder feeding equipment in power plants, mines, and other industries.
