MANUFACTURING STEEL CONCRETE REINFORCEMENTS ON A HIGH SPEED ROLLING MILL

摘要

ABSTRACTSteel concrete-reinforcing rod is manufactured on a highspeed rod rolling mill including a finisher followed bya cooling device for superficial quenching. Thetraction applied to the product leaving the finisher andapproaching the cooling device is arranged to beappropriate to the correct advancement of the rod, byincreasing the drive force of the rod and/or reducingthe braking forces produced in the cooling device.Braking force in the cooling device can be reduced byintroducing air into the cooling water.
