Cemented Carbide Composite Rolls

Product Information

Specialized Materials: We utilize special cemented carbide grades designed for hot rolling rods and ribbed steel bars.
Secure Hydraulic Locking System: Hydraulic nuts, supplied with oil at 100-200 MPa, generate an axial pre-tightening force of 500-1500kN. This fastens the cemented carbide roll rings securely to the mother shafts. The system is practical, reliable, and ensures enhanced composite roll ring performance through proper prestress protection.
Sizing Mill Roll Rings: We offer various cemented carbide roll rings for sizing mills, with diameters of φ300-400mm and thicknesses ranging from 30mm to 159mm.
Hot Rolling Solutions: We provide various composite cemented carbide roll rings specifically for hot rolling ribbed steel bars and rods.
Custom Manufacturing Services: Our capabilities include composite roll design, groove machining, and thread processing.
Compatible Tooling: We supply various compatible tools for machining composite cemented carbide roll rings.

Description

Technical Parameter

Cemented carbide roll rings (also known as Tungsten Carbide Roll Rings) provide excellent thermal conductivity and outperform first-generation cast iron and high-speed steel rolls in 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.
