Abstract
The utility model relates to an ultrasonic gas atomizing linear jet which is characterized in that the ultrasonic gas atomizing linear jet is mainly formed by the combination of a left and a right rectangular atomizing chambers. A linear liquid flowing opening is reserved in the middle of each atomizing chamber, the lower part of each atomizing chamber is provided with an atomizing small hole along the direction of the liquid flowing opening, the small hole and liquid flow from a definite angle that which is in the range of 15 DEG to 75 DEG. The utility model can enable the deposited slabs to be uniform and smooth.
Description
The utility model relates to the ultrasonic atomizatio flash set technology, and a kind of linear nozzle of ultrasonic gas atomization that is used for the plated metal slab particularly is provided.
Spray deposition is that a kind of its basic principle of new technology for preparing rapidly solidified alloy is with atomizer liquid metal to be atomized into fine droplets, is deposited on subsequently on the carrier of a cooling, and rapid condensation becomes the deposition blank.The atomizer that adopts has ultrasonic gas atomization nozzle and Sprey technology nozzle at present, both are nozzle ring, the spray deposition effect also can, but the nozzle ring scattering surface is little, and concentrate the material base median rise that is deposited to become ridge platform shape, formed slab injustice influences the fine finishining of later process.
The purpose of this utility model is, provides a kind of ultrasonic gas atomization linear nozzle, makes that the slab that deposits is even and smooth.
The utility model provides a kind of ultrasonic gas atomization linear nozzle, it is characterized in that: this linear nozzle mainly by about two rectangular spray chambers (1) combine, linear liquid head piece (2) is left in the centre of spray chamber (1), spray chamber (1) below has atomizing aperture (3) along liquid head piece (2) direction, aperture (3) flows angled θ with liquid, and θ is between 15 °～75 °.The utility model is made linear nozzle with the ultrasonic gas atomization nozzle ring design of present extensive use, use linear mozzle simultaneously instead, liquid metal directly enters linear mozzle after flowing out from fusion crucible like this, become a linear liquid stream, become fine droplets by linear nozzle atomization subsequently, be deposited on the mobile carrier.Because the width of linear nozzle is big more than nozzle ring, atomized drop disperses big more than nozzle ring.Thereby can obtain the deposition sheet material of very big width, make this new technology of spray deposition have industrial value.Below by embodiment in detail the utility model is described in detail.
Accompanying drawing 1 is a line style nozzle arrangements side cut-away view;
Accompanying drawing 2 is the positive cut-away view of line style nozzle arrangements.
Embodiment
As shown in the figure, nozzle be about rectangle each one be combined into a nozzle, nozzle is made of water cooling chamber (4) and spray chamber (1), liquid head piece (2) is left in the centre, spray chamber (1) below has several atomizing apertures (3), θ becomes dull and stereotyped at 45 ° of liquid streams from liquid head piece (2) and flows out, high pressure draught is by the ejection of the aperture (3) in the spray chamber (1), be accelerated to the supersonic speed level, this supersonic airstream will smash into the droplet of semi liquid state from the plate shaped metal liquid stream that liquid head piece (2) flows out, this droplet is deposited on the deposition plate of mobile water-cooled, and solidifies rapidly.
Claims (2)
1. linear nozzle of ultrasonic gas atomization, it is characterized in that: this linear nozzle mainly by about two rectangular spray chambers (1) combine, linear liquid head piece (2) is left in the centre of spray chamber, spray chamber (1) below has atomizing aperture (3) along liquid head piece (2) direction, aperture (3) flows angled θ with liquid, and θ is between 15 °～75 °.
2. by the described linear nozzle of claim 1, it is characterized in that: spray chamber (1) is outer also with water cooling chamber (4).
