Abstract

Steel concrete-reinforcing rod is manufactured on a high speed rod rolling mill including a finisher followed by a cooling device for superficial quenching. The traction applied to the product leaving the finisher and approaching the cooling device is arranged to be appropriate to the correct advancement of the rod, by increasing the drive force of the rod and/or reducing the braking forces produced in the cooling device. Braking force in the cooling device can be reduced by introducing air into the cooling water.
