Abstract

The invention discloses a liquid metal cyclone gas atomization powder making device, which comprises a powder making box, an ultra-high-speed motor, a centrifugal turntable, a material cylinder, a high-speed motor, a whirlwind turntable, a spray bar, a screening box, a vibrating motor and a stirring roller. The base is provided with a powder-making box, and the output shaft of the ultra-high-speed motor is connected to the main shaft through a coupling, and the lower end of the main shaft is fixedly connected with a centrifugal turntable; the outer walls of the left and right sides of the powder-making box are fixedly installed with high-speed motors , The inside of the powder making box is also rotatably installed with a cyclone turntable, and the other end of the whirlwind turntable is also connected with a pressurized air pipe. Before powder making, the metal liquid flows out evenly through the action of centrifugal force, so as to effectively ensure that the size of metal particles after powder making is consistent. The strength, so that the metal particle size after shearing 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...
