With the continuous development of industrial technology, wear plates have become an indispensable material in many fields. Among them, 20+20 hardfacing wear-resistant plates are favored because of their excellent wear resistance and high cost performance. This article will introduce the characteristics, production process and practical application of 20+20 hardfacing wear plate in detail.
First, the characteristics of 20+20 surfacing wear-resistant plates.
20+20 hardfacing wear plate is a bimetallic composite material, which is mainly composed of a substrate with high strength and a surfacing layer with excellent wear resistance. The main characteristics of this material are good wear resistance, long service life, low cost, light weight, easy processing and installation. In addition, the 20+20 hardfacing wear plate also has good corrosion resistance and fatigue resistance, which is suitable for various harsh working environments.
Second, the manufacturing process of 20+20 surfacing wear-resistant plates.
The manufacturing process of 20+20 hardfacing wear plate mainly includes the following steps:
1.Preparation of the substrate: select the appropriate steel, and prepare the substrate to be surfacing after cutting, grinding and cleaning.
2.Preparation of surfacing layer: select appropriate wear-resistant materials, and cladding wear-resistant materials on the substrate through arc surfacing welding, plasma surfacing welding, laser surfacing and other processes to form a surface surfacing layer.
3.Heat treatment: heat treatment is carried out on the surfacing material to eliminate internal stress and improve the mechanical properties of the material.
4.Processing and grinding: Machining and grinding the heat-treated material to remove burrs and welds, so that the surface of the material is smooth and flat.
5.Quality inspection: Conduct quality inspection of finished products, including hardness testing, metallographic testing, non-destructive testing, etc., to ensure that product quality meets requirements.
3. Practical application of 20+20 surfacing wear-resistant plates.
20+20 surfacing wear-resistant plates are widely used in coal, mining, metallurgy, electric power, building materials and other fields with serious wear and tear, such as scrapers, ball mills, crushers, vibrating screens and other equipment. Its excellent wear resistance can effectively improve the service life and production efficiency of the equipment, reduce maintenance costs, and have good economic and social benefits.
Taking the coal industry as an example, the scraper is one of the commonly used equipment in coal transportation, and its conveyor chain and sprocket are easy to wear out due to long-term operation in harsh environments. The scraper sprocket and chain made of 20+20 surfacing wear plate can significantly improve its wear resistance and service life, reduce the frequency of replacement and maintenance costs, and improve the production efficiency of coal. In addition, in the building materials industry, 20+20 hardfacing wear plates are also widely used in various crushers and vibrating screens, improving the durability and production efficiency of the equipment.
Fourth, summary. As an excellent bimetallic composite material, 20+20 hardfacing wear plate has excellent wear resistance, corrosion resistance and fatigue resistance, and is widely used in various harsh working environments. The manufacturing process mainly includes the preparation of the substrate, the preparation of the surfacing layer, heat treatment, processing and grinding, and quality inspection. In practical application, 20+20 surfacing wear-resistant plate can effectively improve the service life and production efficiency of equipment, reduce maintenance costs, and have good economic and social benefits. In the future, with the continuous development of science and technology, the manufacturing process and application fields of 20+20 surfacing wear-resistant plates will continue to expand, bringing more convenience and benefits to human production and life.
