Extrusion of I&E ''O'' size tubing to finalize the process. Experiment No. U-31

摘要

Work has been progressing on the development of an extrusion process for I&E tubing. The ultimate object of this development project is to compare the extrusion process from a cost standpoint with, the presently used rolling-drilling process. Various experiments have been performed to determine the optimum billet I.D., the proper follower block technique, the proper tooling parameters for the process, and the proper metallurgical structure of the material for optimum results. This extrusion combines many of the past results as a further determination and refinement of the extrusion process to be used in the final semi-production optimization extrusion. The object of this extrusion was to evaluate the resulted of previous extrusion experiments to determine final process conditions prior to an optimization extrusion.
