ABSTRACT:
The method and the apparatus serve to cool cast billets made of an aluminum alloy after a homogenizing anneal.
The billets emerging from a full-annealing furnace continuously one after the other in the longitudinal direction at a first temperature are guided in-line through a spray unit at a program-controlled feed rate and while being sprayed on all sides with the cooling medium in a program-controlled manner to reach an adjustable surface temperature. The internal and surface temperature of the billets are equalized a short time after leaving the spray unit.
The spray unit for the billets (16) passing through in-line is equipped over its entire length and over the entire periphery of its inner space with nozzles which can be adjusted as a whole, in groups or individually.
