Cyclone gas atomization type powder making device using liquid metals

Abstract

The invention discloses a cyclone gas atomization type powder making device using liquid metals. The device comprises a powder making box, an ultra-high speed motor, a centrifugal rotating disc, a material cylinder, high-speed motors, a cyclone rotating disc, a spraying rod, a screening box, a vibration motor and a stirring roller; the powder making box is arranged on a base, the output shaft of the ultra-high speed motor is connected with a main shaft through a coupler, and the lower end of the main shaft is fixedly connected with the centrifugal rotating disc; the high-speed motors are fixedly arranged on the outer walls of the left side and the right side of the powder making box, the cyclone rotating disc is further rotationally arranged inside the powder making box, and the other endof the cyclone rotating disc is further connected with a pressurizing air pipe. Metal liquids can flow out uniformly through the action of centrifugal force before the powder is prepared, so that thesizes of metal particles after the powder is made are effectively ensured to be consistent, meanwhile, through the combined action of the cyclone rotating disc and the pressurizing air pipe in the powder making process, the strength of the cutting wind force is further improved, so that the particle size of metal subjected to cutting is smaller.

Description

Technical field [0001] The invention relates to the field of metal powder making, in particular to a liquid metal cyclone gas atomization type powder making device. Background technique [0002] Atomized pulverizing is generally divided into water atomized pulverizing and gas atomized pulverizing. When water atomizing pulverizing, use an electric furnace or an induction furnace to melt the metal raw materials into a qualified alloy liquid (generally overheated 100~150℃), and then Inject it into the tundish above the atomizing nozzle, the alloy liquid flows out from the leaking hole at the bottom of the tundish, and when passing through the nozzle, it meets the high-speed airflow or water flow and is atomized into fine droplets. The atomized droplets are atomized in a closed The cylinder quickly solidifies into alloy powder. However, most of the water atomized powder particles are irregular shapes with high oxygen content (above 600×10), which must be annealed. The commonly used...
