Apparatus and methods for hot rolling and treating rod first by depositing the rod in spread-out ring form on a moving conveyor, then gathering it into a relatively loose somewhat offset bundle and thereafter subjecting it to batch treatments among which are conventional annealing, and/or coating and baking as well as new forms of annealing not heretofor practiced.

Methods for hot rolling and treating rod

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.

Process and apparatus for sequentially forming and treating steel rod

A process for forming a ferrous billet into a finished product is disclosed comprising the following steps, in sequence: heating the billet to an appropriate elevated bulk temperature in preparation for rolling; hot rolling the heated billet to produce a semifinished product having an intermediate bulk temperature which is lower than said elevated bulk temperature; cooling the semifinished product to reduce the surface temperature thereof to a level below that of a desired finish rolling bulk temperature; allowing the temperatures of the surface and center portions of the semifinished product to equalize substantially to the level of the desired finish rolling bulk temperature; rolling the semifinished product to a finished product; and, cooling the finished product to an ambient bulk temperature.

Process for forming ferrous billets into finished product

Apparatus for conveying an elongated hot-rolled steel rod in off-set form on a conveyor through a series of cooling chambers. Each chamber comprises a stationary lower section and a removable cover section, the interior walls of each being heat reflective. Each chamber is also provided with tubes supported adjacent the interior walls and controlled in temperature by gas passing through said tubes, said gas being cold or hot, the hot gas being supplied from a plurality of separately controlled burners. The tubes differentially control the rate of heat radiation from the rod rings to compensate for the different rates of radiational heat loss emanating from the top and sides of the rod rings so as to cause the rod to cool uniformly. The side walls of the chamber are provided with adjustable apertures for the escape of radiant energy from the sides of the rod rings. Means are provided for controllably lifting the roof from its completely closed position to one in which the top of the lower section is entirely exposed. Means are also provided for blowing cooling air through the rings. The apparatus provides means for carrying out a process for controlling the loss of heat from the rod by applying radiant heat selectively to the rod, by reflection from the interior walls or by the heated or cooled tubes, or both, substantially in inverse proportion to the accumulated mass of the rod from side to side of the conveyor.
