Abstract

655,652. Extruding. ABBEY, A. (Dow Chemical Co.). Dec. 31, 1948, No. 33640. [Class 83 (iv)] A continuous extruded article 11 of magnesium base alloy is formed in a direction extrusion press having a cylinder cross-sectional area at least 50 times greater than the cross-sectional area of the die by terminating the stroke of the ram 9 before the length of the butt 5 of the billet in the cylinder 6 is less than half its diameter, inserting the next billet 12 and then making the next extrusion stroke so the billet 12 is caused to weld to the butt 5. For extruding strip, the die and cylinder crosssection ratio should preferably be at least 1 : 90 and, for round rod, 1 : 140. To prevent trapping of air, the end of the ram has a conical or wedge-shaped depression 10 which forms a convex surface on the end of the billet so that air is forced out past the new billet as it. is welded to the butt. Only the first billet to be extruded need be heated, succeeding billets being heated from the butt and from the mechanical working of the material. The magnesium alloy may contain zirconium. Specification 10629/00, [Class 83], is referred to.
