Shape structure liner yttrium jet pipe due to yttrium oxide and Titanium melt minor response, and generates stabilization after reacting
Soakage layer prevent reaction continues to occur, therefore yttrium can be used as be atomized titanium valve when jet pipe；The taper of ceramic spray pipe 19
Whether successfully there is direct relation with caliber and cold crucible rising pouring.It is shown in Table 1 by testing ginseng, it can be seen that when ceramic spray pipe is bored
Even if power can not realize greatly casting very much when spending a≤60 °, main cause is the contact surface with crucible bottom because of ceramic spray pipe 19
Product (film-cooled heat) is too big, and the heat of the solid metallic in ceramic spray pipe 19 rapidly take away by cooled water, can not make its fusing；And
Casting can not be realized when ceramic spray pipe taper a >=110 °, main cause is because the solid phase that casting induction coil can cover
Metal surface is too small, therefore the heat for the solid metallic being fed in ceramic spray pipe 19 is also very little, and solid metallic cannot be melted.
The time for casting, interrupting and recovering used when ceramic spray pipe taper a is equal to 90 ° is most short.
Shown in table 2, influence of the ceramic spray pipe internal diameter to casting is reflected.Ceramic spray pipe nozzle pluggage scope for 10~
100mm, the angle of ceramic spray pipe is 90 °.Casting can not be realized when ceramic spray pipe nozzle pluggage is 10mm, and main cause is
Because the effect of induced electricity miscarriage raw electromagnetic force and metal surface tension；Although when ceramic spray pipe nozzle pluggage is 100mm
Success can be cast, but casting cannot be interrupted, main cause is because ceramic spray pipe nozzle pluggage is excessive to cast the flow velocity flowed too
Greatly, metal scull can not be grown, and can not be blocked ceramic spray pipe and be realized interruption casting.Therefore the taper of ceramic spray pipe chooses 90 °, spray
Pipe caliber chooses DN25.
Yttrium jet pipe, which is also prevented from titanium liquid scull, makes the joint-cutting short circuit at crucible bottom, smelting efficiency is improved, referring to table
Shown in 2, when the taper at crucible bottom chooses 90 °, without ceramic spray pipe in crucible bottom, when internal diameter L >=40 mm of jet pipe spout, being capable of bottom
Note, rising pouring is unable to as internal diameter L≤30 mm of jet pipe spout；There are ceramic spray pipe, internal diameter L >=20 of jet pipe spout in crucible bottom
It being capable of rising pouring during mm.It can be seen that influence of the installation ceramic spray pipe to titanium alloy rising pouring.
Table 1.
Table 2.
Table 3.
In powder by atomization, furnace body domestic demand pours argon gas to micro-positive pressure, at this moment sprays disk and is passed through gases at high pressure, gas is ejected in
At nozzle generate negative pressuren zone ejector action is played to the molten metal of outflow, at the same time in furnace body gas also can by coil with
The gap of spray disk enters spray disk, can generate crossflow disturbing influence powder quality to the metal fluid column flowed out, more sternly
The meeting of weight makes metal fluid column deflection that spray disk be caused to block or burn.It below ceramic spray pipe and is worn using yttrium sheathed catheter
Cross spray disk, the interference for thering is ceramic conduit to be protected from beam wind around the Titanium liquid that when rising pouring flows out, even if metal fluid column is inclined
It tiltedly also can only get lodged in ceramic conduit, titanium liquid, which will not flow out, burns spray disk and equipment.
The present invention can be passed through the pressure of spray disk gas by changing and change ceramic spray pipe end aperture to obtain difference
The powder of grain size.Find that when the argon pressure for being passed through spray disk be 5MPa through overtesting, when ceramic spray pipe end aperture is DN6, D50
Between 100 μm -150 μm；Be passed through spray disk argon pressure it is constant, when ceramic spray pipe end aperture is changed to DN5, D50 80 μm-
Between 100 μm；The argon pressure for being passed through spray disk is promoted to 6.7MPa, ceramic spray pipe end aperture for DN5 when, D50 50 μm with
Under.Since the present invention using high pressure low temperature argon gas saves source of the gas heating cost as atomizing gas, be averaged it is per second go out powder
0.25kg and powder cool down rapidly, and atomization can take powder after completing 30 minutes, improve work efficiency.
Vent gas of the present invention can just eventually enter into mechanical pump vacuum system after dry filter filters, and can effectively receive
Volatile matter, grease, dust generated in collection fusion process etc., avoids scuffing of the dust particles to mechanical pump rotor, slows down to pump
The pollution of oil.Meanwhile to prevent in fusion process since water jacketed copper crucible burn through cooling water caused by accident connects with melt liquid
Raw unpredictable reaction condition is triggered, furnace body sets the diaphragm explosion-proof decompression device of independent safety valve and big orifice.
Above with respect to the specific descriptions of the present invention, it is merely to illustrate the present invention and is not limited to the embodiment of the present invention and is retouched
The technical solution stated.It will be understood by those of ordinary skill in the art that still can modify to the present invention or equivalent substitution,
To reach identical technique effect.As long as meet using needs, all in the protection domain of invention.
