Device for One- and Two-Sided Molding of Refractory Metal Powders Into Electric-Arc Melting Electrode Workpieces

The first devices for preparing workpieces (bars) of refractory metal powders (tungsten and molybdenum) in the form of dismountable steel dies installed in a hydraulic press of special construction with vertical and horizontal cylinders were developed by the American firm General Electric in 1909.

Zusammenfassung:The first devices for preparing workpieces (bars) of refractory metal powders (tungsten and molybdenum) in the form of dismountable steel dies installed in a hydraulic press of special construction with vertical and horizontal cylinders were developed by the American firm General Electric in 1909. This article considers known and new die and device constructions for molding bars from refractory metal powders developed by scientists of Ural scientific schools.
