Abstract
A method and apparatus for quenching steel rod in a high speed rolling mill is provided wherein a liquid coolant is preliminarily applied to the rod prior to its exiting from the mill finishing train in order to increase the column strength of the exiting rod by lowering the surface temperature thereof to less than about 950.degree. C. Thereafter, as the rod progresses through additional liquid cooling devices on the way to the mill laying head, tractive forces are applied to the rod. The aforesaid increase in rod column strength acts in concert with the application of tractive force to insure that the rod has sufficient rigidity and forward momentum to pass from the finishing train through the liquid cooling devices and to and through the laying head.
