Equipment and technology for preparing metal powder

Abstract

The invention provides equipment and technology for preparing metal powder, which are used for atomizing a raw material rod into metal powder. The equipment for preparing metal powder comprises a driving mechanism for driving the raw material rod to rotate, wherein the driving mechanism comprises a motor of the driving mechanism, a driving roll of the driving mechanism and a driven roll of the driving mechanism; the driving roll of the driving mechanism is connected to the motor of the driving mechanism; the driven roll of the driving mechanism is used for pressing the raw material rod; a clamping space for clamping the raw material rod is arranged between the driving roll of the driving mechanism and the driven roll of the driving mechanism; the driving roll of the driving mechanism and the driven roll of the driving mechanism clamp the raw material rod to rotate; and the diameter of the driving roll of the driving mechanism is more than 2 times that of the raw material rod. According to the technology, the driving roll of the driving mechanism and the driven roll of the driving mechanism clamp the raw material rods to rotate so that the rotating speed of the raw material rod is higher than 30 thousand turns / minute. The equipment can be used for preparing powder of which the particle size is below 1mm, and the yield of the fine powder with particle size below 50mu m is very high.

Description

technical field [0001] The invention relates to the field of metallurgy, and belongs to equipment and a process for preparing metal powder, in particular to an equipment for preparing metal powder by using a plasma atomization process and a process for preparing metal powder by using a plasma atomization process. Background technique [0002] The fine metal powder can be prepared by argon atomization, nitrogen atomization, water atomization and plasma atomization. At present, the plasma atomization process has been used to produce metal powder. The plasma atomization process is to use the plasma gun installed in the atomization chamber to act on the metal raw material rod extending into the atomization chamber. The metal raw material rod is driven by the driving mechanism (mainly the motor) to rotate at high speed in the atomization chamber. A centrifugal phenomenon occurs, and is atomized into metal powder under the action of high-temperature heating and melting of the pla...
