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.
Claims5
In a method of processing a plurality of stationary steel work pieces exposed to the ambient atmosphere, the steps of
- disposing a portion of said plurality of work pieces in a first location,
- disposing a portion of said plurality of said work pieces in a second location,
- subjecting said work pieces in said first location to a draft of forced air moving in a generally vertical direction, and
- subjecting said work pieces in said second location to a draft of forced air moving in a generally upward direction,
- at least two or more of said work pieces in each location being juxtaposed sufficiently close to one another to be subject to slack quenching in the absence of said draft of forced air.
