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
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).

1. 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 perpend
1. 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. 2. 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 clamping and rotating the billet as the cooling medium is supplied to the billet. 3. The apparatus as claimed in claim 2, wherein the device for clamping and rotating the billet comprises: a rail positioned above said housing; and a crab suspended from and movable along said rail, said crab including a pair of rotatable shafts for clamping the billet therebetween, wherein the crab can be moved along the rail to move the billet axially through the cooling ring while the billet is rotated by said rotatable shafts. 4. 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; and 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, wherein said cooling ring comprises a plurality of separate sections, and each of said sections is associated with one of said supply lines such that the quantity of cooling medium supplied to each of said separate sections can be varied independently of the other of said sections. 5. The apparatus as claimed in claim 1, wherein said cooling ring is adapted to vary the quantity of cooling medium supplied around the circumference of the billet. 6. The apparatus as claimed in claim 1, wherein said cooling ring is oriented so that the billet can be passed through the cooling ring while the billet is in a vertical orientation. 7. The apparatus as claimed in claim 1, wherein said housing includes gaskets provided on circumferential housing edges. 8. The apparatus as claimed in claim 1, wherein said cooling ring includes annular nozzles adapted to spray the cooling medium around the entire circumference of the billet.
