Description

Technical Parameter

Cemented carbide roll rings (also known as Tungsten Carbide Roll Rings) offer excellent thermal conductivity and outperform first-generation cast-iron and high-speed-steel rolls in terms of heat resistance, wear resistance, and strength, with minimal hardness reduction at high temperatures. Developed alongside high-speed wire rod mills, they are now extensively applied in the finishing stands for manufacturing high-speed wire, rebar, and deformed steel bars.
