Composite cemented carbide roll rings for hot rolling rode and ribbed steel bars
Installed on the finished products stands and stands afore of rods and twist steel rolling machines can substantially reduce the times of groove changes and roll changes, reduce labor intensity, increase productivity, improve surface quality and yield of rolled material, thus achieving outstanding economic benefits.
Special cemented carbide grades
Special cemented carbide grades are used for hot rolling rods and ribbed steel bars with hydraulic nuts locking devices ad in-feed of oil with a pressure of 100-200Mpa, the hydraulic nuts create an axial preloaded force of 500-1500KN and fasten the cemented carbide roll rings to the mother shafts. The devices are practical in use and reliable and they can insure higher performance of composite cemented carbide roll rings under the protection of a proper preloaded force.
Various cemented carbide roll rings are available with diameter of φ300-400mm and thickness of 30-159mm for rod reducing and sizing machines.
Various composite cemented carbide roll rings for hot rolling ribbed steel bars and rods. Services is to be rendered for the design, grooving machining and rib machining of composite cemented carbide roll rings.
Various compatible tools can be provided for machining composite cemented carbide roll rings.
