An improved quenching process is provided by supplying a secondary quenching tank with cooling medium from the pit of a forging press. Only heated, but unprocessed, billets are quenched in the secondary quench tank. The cooling medium from the pit of the forging press is not as clean as fresh water, but because the billets will be reheated, forged and quenched later with a fresh or conditioned cooling medium, the secondary tank quenching medium quality is not restrictive. |
