Abstract
A series of controlled quenching of elevated temperature steel work pieces includes locating hot work pieces on a support at distances from one another sufficient to avoid slack quenching and subjecting the work pieces to a forced draft at a speed which results in consistent uniformity of hardness and uniformity of grain size of which about 10 MPH is exemplary, and an apparatus therefore which provides two pass cooling so that minimum horsepower is used and environmental degradation is avoided.
