Description
Technical field
The invention belongs to metal powder-making technique field, and in particular to a kind of adjustable atomization based on water atomization legal system powder
Bucket.
Background technology
Metal dust plays more and more important role in development of modern industry, is widely used in spraying, surfacing
With the field such as laser melting coating.The method for preparing metal dust used at present has mechanical crushing method, water atomization and aerosolization
Method etc..Mechanical crushing method mainly by crushing, smash and be ground etc. to act on solid metallic is broken into powder.Water atomization is just
It is using water as medium, flow of liquid metal is broken into droplet and the method for being condensed into metallic particles using high-velocity flow.Gas
Atomization is exactly using gas as medium, and its principle is similar to water atomization, is broken into flow of liquid metal using high velocity air small
Drop simultaneously condenses the method as metallic particles.Because the specific heat capacity of water is big, cooling velocity is fast, and powder made from water atomization
Granularity, oxygen content, structure and shape etc. control can be adjusted by changing the atomization parameter of device, so in metal system
Being most widely used in pink collar domain.
Atomization bucket is water atomization legal system powder core, and the spray regime of the atomized water in bucket can be divided into V-arrangement injection and ring
Shape is sprayed.The angle of nozzle ring is that fixed and slit width uniformity is difficult to ensure that melt easily solidifies in circular cone.V-arrangement sprays
Principle be to make metal liquid stream high in infall (atomization focal point) by mode of jet by two strands of plate-like atomizing mediums
The process that pressure water smoke atomization smashes.Under same hydraulic pressure, V-arrangement injection fine powder rate is higher.Atomization angle is one in flouring technology
Individual important parameter, research show that atomization angle all has a certain impact to sphericity, granularity and apparent density of powder etc., right
The requirement of powder property is different, and selected atomization angle also needs to change therewith.Current existing water atomization powder manufacturing apparatus
Atomization angle is non-adjustable or regulation is difficult, it is difficult to meets the requirement of different process.
Metal dust also has certain requirement to oxygen content used in some fields.Research shows, water atomized powder oxygen
Change and mainly occur in atomization process, moment that metal liquid stream is crashed to pieces, solution expansion rapider than surface, metal and water and
Oxidation reaction drastically occurs at high temperature for the water vapour around grain, and using inert gas shielding, the oxygen content of powder can be big
Width reduces.Inert gas injection apparatus is installed, oxygen content in power can be made to be reduced to 500ppm from 5000ppm.
Increase extra cooling water nozzle below traditional water atomizing nozzle, can be achieved to carry out secondary-atomizing to metal stream.Grind
Study carefully and show, secondary-atomizing effect can make the powder of part ot-yet-hardened further be broken so that powder fining；Secondary-atomizing
Quenching effect can make powder cooling velocity by 103K/s increases to 104K/s；Due to the raising of powder cooling velocity, powder can be made
Oxygen content reduces, and particle profile becomes more irregular.Seldom it is provided with and is used in existing water atomization equipment in the market
The nozzle of secondary-atomizing, it is difficult to meet the needs of some techniques.

The atomization bucket that Figure 14 is the present invention enters water-filling, the schematic diagram of water combination atomization (secondary-atomizing), and principle specifically describes
It is as follows：Two strands of plate-like high-pressure atomization water 10 are sprayed into atomization bucket by two atomizing water nozzle 3-1-10, it is atomized folder
Angle is α, sprays into two strands of high-pressure cooling waters 11 into atomization bucket by two cooling water nozzle 3-2-10, it is β that it, which is atomized angle, liquid
State metal is entered in atomization bucket by ceramic crucible 2 forms flow of liquid metal 9, and flow of liquid metal 9 is in two strands of high-pressure atomization water 10
Infall (atomization focal point) be crashed to pieces into droplet, the high-pressure cooling water 11 that two cooling water nozzle 3-2-10 spray is immediately
And cool down the molten drop after atomization rapidly, oxidation reaction occurs at high temperature so as to suppress it.Utilize water, water combination mist
The oxygen content of powder is low made from the method for change (secondary-atomizing), and granularity is small.Atomized water is atomized angle α and cooling water atomization angle
β has a certain impact to sphericity, granularity and apparent density of powder etc., therefore, during requirement difference to powder property, institute
The atomization angle of selection also needs to change therewith.
