ABSTRACT:
A process and apparatus for rolling and cooling medium to high carbon steel rod is provided wherein the rod is rolled at high speed and laid in rings directly onto a conveyor at high temperature. Thereafter high velocity hot water is sprayed onto the rings to cool them to a temperature near to but above A.sub.3. Transformation is then started while applying air to the rod, and while substantial parts of the rod are transforming, further accelerated cooling is again applied to the rod.
