Wear-resistant materials refer to materials that can maintain good stability and wear resistance under wear conditions. In the manufacture of thermal power forgings, the commonly used wear-resistant materials include high manganese steel, wear-resistant cast iron, wear-resistant alloy steel, etc.
High manganese steel
High manganese steel is a kind of material with good toughness and wear resistance, which can maintain good surface hardness and toughness under strong impact and wear conditions. In the manufacture of thermal power forgings, high manganese steel is mainly used to manufacture wear-resistant parts such as coal mills and crushers.
Wear-resistant cast iron
Wear-resistant cast iron is a kind of material with good wear resistance and impact resistance, and its surface hardness is high, which can effectively resist wear and impact. In the manufacture of thermal power forgings, wear-resistant cast iron is mainly used to manufacture wear-resistant parts such as ball mill and vibrating screen.
Wear-resistant alloy steel
Wear-resistant alloy steel is a kind of steel that improves the wear resistance of the material by adding alloying elements, and its surface hardness and toughness are good, which can effectively resist wear and impact. In the manufacture of thermal power forgings, wear-resistant alloy steel is mainly used to manufacture conveyor belts, rollers and other wear-resistant parts.
In the manufacture of thermal power forgings, the research and application of wear-resistant materials mainly adopt the following methods:
Experimental research
The wear resistance, toughness, strength and other indexes of different wear-resistant materials were tested and analyzed by simulating actual working conditions in the laboratory to provide reference for practical application.
Numerical simulation
The wear process of different wear-resistant materials was simulated and analyzed by finite element analysis, and the wear life and wear mechanism of the materials were predicted to provide a basis for material selection and optimization.
Theoretical analysis
Through the theoretical analysis of the composition, structure and properties of the wear-resistant materials, the wear-resistant mechanism of the materials was revealed, which provided theoretical support for the development of new materials and the optimization of existing materials.
In practical applications, wear-resistant materials play an important role in the manufacture of thermal power forgings. Here are some specific cases:
In the coal mill, the grinding parts made of high manganese steel can effectively resist wear and impact, and improve the operating efficiency and service life of the equipment.
In the conveyor belt, rollers made of wear-resistant alloy steel effectively resist wear and corrosion, reducing maintenance costs and downtime.
In the crusher, the crushing teeth made of wear-resistant cast iron can effectively break materials, improve the crushing efficiency and output of the equipment.
Through the application of wear-resistant materials, the life of thermal power forgings has been significantly extended, the maintenance cost has been effectively reduced, and good economic and social benefits have been created for enterprises.

Through experimental research, numerical simulation and theoretical analysis, the wear resistance mechanism of the materials can be revealed and the properties of the materials can be optimized. Future research directions include developing new wear-resistant materials, researching the composite technology of wear-resistant materials and surface treatment technology to further improve the life and performance of thermal power forgings. At the same time, with the adjustment of the energy structure and the improvement of environmental protection requirements, the requirements for the wear resistance and environmental protection performance of thermal power forgings will continue to improve, which will provide a broader space for the research and application of wear-resistant materials.
