Abstract
Apparatus for cooling billets (9), preferably formed of aluminum. The apparatus includes a housing (2) provided with openings (3) for axial passage of the billet through the housing, a cooling ring (4) arranged inside of the housing, and supply lines (6) for supplying a cooling medium to the housing. The cooling medium is supplied to the billet (9) in order to achieve uniform cooling, i.e. cooling without a temperature gradient, around the entire circumference of the billet. The apparatus is capable of rotating the billet while the cooling medium is supplied uniformly around the circumference of the billet (90).
Claims8
An apparatus for cooling a billet prior to an extruding operation, said apparatus comprising:
- a housing having openings to permit axial passage of the billet through the housing;
- at least one cooling ring, disposed in said housing, for directing a cooling medium in a direction that is perpendicular to a longitudinal axis of the billet;
- a plurality of supply lines for supplying the cooling medium to said cooling ring, wherein the cooling ring is adapted to supply the cooling medium around the entire circumference of the billet to achieve uniform cooling of the billet;
- and
- a device for rotating the billet as the cooling medium is supplied to the billet.
