Abstract

547,080. Squirting. HIGH DUTY ALLOYS, Ltd., and HERON, J. A. April 7, 1941, No. 4619. [Class 83 (iv)] In extruding metal or alloy the rate of extrusion is controlled to keep the temperature of the metal 4 about to enter the die 6 constant. This may be done by hand in accordance with the temperature indicated for instance by the dial 17 of a pyrometer, or automatically, as shown, by connecting a thermo-electric pyrometer 18 to a relay and motor operated throttle valve at 30 in the main 31 leading to the ram-cylinder 1. The elements 15, 16 of the thermo-couple are mounted in or near the die 6 and the leads may pass through the die-withdrawing piston-rod, 12. The extrusion 4a may be cooled to the desired temperature by an annular spray 38 and shield 36. In a modification both elements 15, 16 are arranged in one pocket in the die, one being connected by wire to the pyrometer and the other by earthing to the die.
