Product Description
Cemented carbide flat-head nails
Cemented carbide nails are a wear-resistant material with high hardness, excellent strength, and good impact resistance performance, used in roller press rollers. These can significantly enhance the wear resistance of the roller surface and extend the service life of the roller press.
The material used to manufacture cemented carbide nails is tungsten carbide-cobalt, with tungsten carbide (WC) as the matrix and cobalt (Co) as the binding phase, produced via powder sintering technology. The HRA hardness of cemented carbide nails is approximately 87, offering high hardness, excellent wear resistance, and superior impact toughness—features that significantly enhance both the service life and operational efficiency of roller presses.
Depending on the specific application requirements, cemented carbide nails are divided into two types: arc nails and flat-head nails with bevels. Arc nails feature edges with a curved bevel to prevent localized damage during production, transportation, installation, and use; while flat-head nails with bevels have edges that are flattened at the bevel, providing superior resistance to fracture and impact.
Additionally, the sintering of cemented carbide nails is carried out using pressure sintering, achieving good density and high product strength. A special process is employed to relieve surface stresses after machining and enhance surface hardness, thereby improving the product's performance.
Scope of application of tungsten carbide nails
Primarily used for crushing in roller presses. The roller press is an efficient crushing equipment, and roller casings are key components in critical machinery such as cement, mining, thermal power, and coal chemistry—machinery whose performance directly determines the production efficiency of the entire line.
