Plasma rotating electrode atomization powdering device and method

Abstract

The invention discloses a plasma rotating electrode atomization powdering device and method and relates to the technical field of power metallurgy. According to The device, the problem that low metal powder preparation efficiency is caused by discontinuous feeding of electrode bar material and low rotating speed of an existing plasma rotating electrode powdering device can be solved. According to the device, a bar material moves on a bar material rollgang and a material pushing device, stays on a V-shaped material feeding plate, and is pushed into a bar material rotating device through the material pushing device arranged on one side of the V-shaped material feeding plate; the bar material rotating device is arranged on a furnace body; a pair of inner pull rods is arranged on two sides of the bar material, and the inner walls of the inner pull rods are in contact with the bar material; the outer wall portions of the inner pull rods are in contact with the inner wall of a hollow main shaft, and the outer walls of one ends of the inner pull rods are connected with an air cylinder; the inner wall of one end of the hollow main shaft is in contact with the inner pull rods and outer clamping heads in sequence; the inner walls of a pair of outer clamping heads are in contact with the bar material; the inner walls of a pair of V-shaped sealed inner walls are in contact with the bar material, and t V-shaped sealed outer walls are in contact with the inner walls of the inner pull rods.
