Abstract
The specification discloses a dynamic self-adjusting taper quenching system for producing isothermal extrusions in a nonferrous extrusion operation. The quenching system includes a quenching unit, a computer for controlling the quenching unit, and an interface for reading the extrusion press ram pressure. A target quenching profile is stored in the computer. The computer samples the ram pressure during extrusion of a quenched billet and adjusts the target quenching profile for subsequent billets as a function of the sampled pressures.
