Extrusion and Rolling

National Laboratory: 
Oak Ridge National Laboratory
Processing/Manufacturing Class: 
Thermo-mechanical processing
Description: 

The 4508 high is equipped with an operation 1250-ton extrusion press. Nitrogen over water processes everything from light metals, such as Al, Mg, and Ti alloys, to steels, nickel-based alloys, and refractory metals. The press is supported by a series of furnaces that allow processing up to 1600°C. In addition to the extrusion press, the high bay is equipped with three operational rolling mills: a combination 2-high/4-high with 11-in. working face and servo-hydraulic down-screws, suitable for plate and foil. Carbide work rolls allow for foil rolling of high-flow stress materials. A 2-high mechanical hot mill also is available.

Capability Bounds: 

The extrusion press is limited to 5.5 Ø feed and has a number of dies in inventory. Custom dies also can be designed. The 2-high/4-high mill is limited to 1-in. x11 in. wide material, and the 2-high hot mill is limited to 3-in. thick x 8 in. wide material.

Unique Aspects: 

The extrusion press is the only operating press in the U.S. Department of Energy (DOE) laboratory complex. The 2-high/4-high mill is unique in that the carbide rolls allow for high specific pressure on difficult to deform materials. This equipment also is unique within the DOE complex.

Availability: 

The equipment is in a service center and is available for immediate use with qualified personnel.
