Composite cemented carbide roll rings for hot rolling rode and ribbed steel bars
Cemented carbide >>> Composite cemented carbide roll rings for hot rolling rode and ribbed steel bars
ˇˇˇˇInstalled on the front stands of machines for rolling ribbed steel bars and rods,composite roll rings 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. ˇö Special cemented carbide grades are used for hot rolling rods and ribbed steel bars ˇö With hydraulic nuts locking devices and in-feed of oil with a pressure of 100-200Mop,the hydraulic nuts create an axial pretightening 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 performances of composite cemented carbide roll rings under the protection of a properperload stress. ˇö Various cemented carbide roll rings are avaitable with diameters of 300-400mm and thicknesses of 30-159mm for rod reducing and sizing machines. ˇö Various cemented carbide roll rings for hot rolling ribbed steel bars and rods. ˇö Service is to be rendered for the design,groove machining and rib machining of composite cemented carbide roll rings. ˇö Various compatibel tools can be provided for machining composite cemented carbide roll rings.
