A cemented carbide roll ring is a vital component in rolling mills, commonly used in the steel, metal, and manufacturing industries. These roll rings are made from cemented carbide-a composite material of tungsten carbide (WC) and a metallic binder, often cobalt or nickel. This combination ensures exceptional hardness, wear resistance, and toughness, making cemented carbide roll rings ideal for high-speed and heavy-duty rolling operations.
Tungsten carbide roll rings are the standard application in high speed wire rod finishing block and is getting more popular in some other hot and cold forming .
