Steel Conveyor Rollers for Heavy-Duty Material Handling

Performance characteristics

Outstanding wear resistance: It features excellent thermal conductivity and high-temperature hardness, and has a strong ability to resist thermal wear. It can effectively resist abrasive wear, impact wear, adhesive wear (intermetallic wear), high-temperature wear, corrosive wear and two or more types of combined wear, and can significantly extend the service life of workpieces under harsh working conditions.

Outstanding process performance: During the welding process, the arc is stable, the droplet transition is uniform, and the spatter phenomenon is less and easier to remove, providing convenience for the welding operation and also ensuring a clean welding working environment. The weld bead formation is aesthetically pleasing, and the weld surface is smooth and flat. It not only meets the high appearance quality requirements but also ensures the strength and reliability of the welded joint. The slag removal is easy, which greatly improves the welding efficiency and reduces the workload of subsequent cleaning and processing.

High-efficiency deposition characteristics: Under the same welding current conditions, the current density of wear-resistant flux-cored wire is high, the deposition speed is fast, and the productivity is significantly higher than that of some other welding materials. This means that in actual production, welding work can be completed more quickly, production efficiency can be improved and production costs can be reduced.

Flexible composition adjustment: The composition and proportion of the powder can be precisely adjusted according to the complex and changeable working conditions on site and the specific requirements for the performance of the workpiece. In this way, wear-resistant flux-cored wires that best meet the actual usage requirements can be customized, providing personalized solutions for diverse application scenarios in different industries.

Excellent crack resistance: During the welding process, wear-resistant flux-cored wires exhibit superior crack resistance, effectively preventing defects such as cracks in the surfacing layer and ensuring the quality and reliability of the surfacing layer. This is particularly important for some large workpieces or components with complex shapes, as the presence of cracks may seriously affect the service life and safety of the workpieces.

Alloy composition and function

Chromium (Cr) element: It helps form hard carbides, significantly enhancing the hardness and wear resistance of the surfacing layer, enabling it to better withstand the friction and scraping of materials and effectively resist abrasive wear.

Molybdenum (Mo) element: It can enhance the strength of the surfacing layer in high-temperature environments, improve its resistance to thermal fatigue, and ensure that equipment components maintain a stable working state during high-temperature operations. It is suitable for high-temperature wear conditions.

Nickel (Ni) element: It can enhance the toughness and corrosion resistance of the surfacing layer, enabling the surfacing layer to maintain good adaptability and durability even in complex working conditions with corrosive factors or impact, thereby extending the service life of the workpiece.

Vanadium (V), niobium (Nb) and other elements: They can optimize the microstructure of the surfacing layer, refine the grains, thereby comprehensively enhancing the mechanical properties of the surfacing layer, enabling it to work reliably under different working conditions and improving the overall performance of the surfacing layer.

Application field

In the field of mining machinery: It is widely used in the surfacing repair and manufacturing of components such as hammer heads and jaw plates of crushers, liners of ball mills, and drill bits for mining. These components are subject to tremendous wear and impact during the process of ore mining and crushing. The use of wear-resistant flux-cored wires can significantly enhance their wear resistance and service life, reduce the frequency and cost of equipment maintenance, and improve the production efficiency of the mine.

In the field of cement equipment: It is often used for surfacing welding of components such as grinding rollers, grinding discs of cement mills, and blades of powder separators. During the cement production process, these components are constantly worn and eroded by cement clinker, and thus have extremely high requirements for wear resistance. Wear-resistant flux-cored wires can provide reliable wear-resistant protection for these components, ensuring the normal and stable operation of the equipment, reducing downtime caused by component wear, and improving the economic benefits of cement production.

In the field of metallurgical equipment: It is applicable to the surfacing welding of components such as rolls of steel rolling mills, continuous casting rolls, material clocks of blast furnaces, and top equipment of furnaces. These devices operate under harsh conditions of high temperature, high pressure and high wear, and have very strict requirements for the comprehensive performance of materials. Wear-resistant flux-cored wire, with its excellent wear resistance, heat resistance and corrosion resistance, can meet the special requirements of metallurgical equipment, extend the service life of equipment, and improve production efficiency and product quality.

In the field of construction machinery: It can be used for surfacing and strengthening components such as buckets, bucket teeth, and track plates of construction machinery like loaders, excavators, and bulldozers. These components frequently come into contact with materials such as soil, stones and ores during operation, resulting in extremely severe wear and tear. By using wear-resistant flux-cored wires for surfacing, the wear resistance and strength of components can be effectively enhanced, the operational capacity of construction machinery under harsh working conditions can be improved, equipment failures can be reduced, and maintenance costs can be lowered.
