Electric Rolling of Metal Powder in Roller-Electrodes

  • I. M. Mal'tsev


The effect of electric voltage in roller-electrodes during electric rolling of metal powders has been studied. Equations for calculating voltage are derived. Values of electric breakdown are determined by experiment. Optimum voltages are established for rolling commonly used metal powders.
