Shape structure liner yttrium jet pipe, due to yittrium oxide and Titanium liquation minor response, and generates stable after reaction
Soakage layer stops reaction from continuing to occur, and therefore yttrium can be used as being atomized jet pipe during titanium valve；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 it can be seen that working as ceramic spray pipe cone by testing ginseng
Even if during degree a≤60 °, power is very big nor realizes casting, main cause is because the contact surface of ceramic spray pipe 19 and crucible bottom
Long-pending (film-cooled heat) is too big, and take away it is impossible to make it to melt rapidly by cooled water for the heat of the solid metallic in ceramic spray pipe 19；And
When ceramic spray pipe taper a >=110 ° nor realize casting, main cause is because casting the solid phase that can cover of induction coil
Metal surface is too little, is therefore fed to the heat of solid metallic in ceramic spray pipe 19 also very little, solid metallic can not be melted.
When ceramic spray pipe taper a is equal to 90 °, casting, the interruption and recovery time used is the shortest.
Shown in table 2, reflect the impact to casting for the ceramic spray pipe internal diameter.Ceramic spray pipe nozzle pluggage scope be 10～
100mm, the angle of ceramic spray pipe is 90 °.Cannot realize when ceramic spray pipe nozzle pluggage is for 10mm casting, main cause is
Because the electromagnetic force that faradic current produces and the effect of metal surface tension；Although when ceramic spray pipe nozzle pluggage is 100mm
Can cast successfully, but can not interrupt casting, main cause is because the flow velocity of ceramic spray pipe nozzle pluggage excessive casting stream too
Greatly, metal scull cannot grow and realize interrupting casting it is impossible to block ceramic spray pipe.The taper of therefore ceramic spray pipe chooses 90 °, spray
Pipe caliber chooses dn25.
Yttrium jet pipe is also prevented from titanium liquid scull and makes the joint-cutting short circuit at crucible bottom, improves smelting efficiency, referring to table
Shown in 2, when the taper at crucible bottom chooses 90 °, no ceramic spray pipe in crucible bottom, being capable of bottom during internal diameter l >=40 mm of jet pipe spout
Note, is unable to rising pouring as internal diameter l≤30 mm of jet pipe spout；Ceramic spray pipe, internal diameter l >=20 of jet pipe spout are had in crucible bottom
Being capable of rising pouring during mm.It can be seen that installing the impact to titanium alloy rising pouring for the ceramic spray pipe.
Table 1.
Table 2.
Table 3.
In powder by atomization, body of heater domestic demand pours argon to pressure-fired, and at this moment spray disk is passed through gases at high pressure, and gas is ejected in
At nozzle produce negative pressuren zone to flow out molten metal play ejector action, meanwhile in body of heater gas also can by coil with
The gap of spray disk enters spray disk, can produce crossflow disturbing influence powder quality to the metal fluid column flowing out, more sternly
The meeting of weight makes metal fluid column deflection cause the blocking of spray disk or burn.And worn below ceramic spray pipe using yttrium sheathed catheter
Cross spray disk, around the Titanium liquid flowing out during rising pouring, have ceramic conduit to be protected from the interference of beam wind, even if metal fluid column is inclined
Tiltedly also only can get lodged in ceramic conduit, titanium liquid will not flow out and burns spray disk and equipment.
The present invention can obtain difference by changing the pressure being passed through spray disk gas and change ceramic spray pipe end aperture
The powder of particle diameter.Find that when the argon pressure being passed through spray disk be 5mpa through overtesting, when ceramic spray pipe end aperture is dn6, d50
Between 100 μm -150 μm；The argon pressure being passed through spray disk is constant, when ceramic spray pipe end aperture is changed to dn5, d50 80 μm-
Between 100 μm；Lifting be passed through spray disk argon pressure arrive 6.7mpa, ceramic spray pipe end aperture for dn5 when, d50 50 μm with
Under.Because the present invention saves source of the gas heating cost using high pressure low temperature argon as atomizing gas, averagely per second go out powder
0.25kg and powder cooling is rapid, atomization just can use powder after completing 30 minutes, improves work efficiency.
Vent gas of the present invention just can eventually enter into mechanical pump vacuum system after dry filter filtration, can effectively receive
The volatile matter of generation, oils and fatss, dust etc. in collection fusion process, it is to avoid the scuffing to mechanical pump rotor for the dust granules, slow down to pump
The pollution of oil.Meanwhile, for preventing in fusion process because the unexpected water jacketed copper crucible burn through cooling water leading to is connect with melt liquid
The raw unpredictable reaction condition of triggering, the diaphragm explosion-proof decompression device of the independent relief valve of body of heater setting 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 scheme stated.It will be understood by those within the art that, still the present invention can be modified or equivalent,
To reach identical technique effect.As long as meet using needs, all in the protection domain of invention.
