Device is used cooperatively with microwave high-temperature high vacuum furnace, i.e., carried out by the Rapid recovery device together with microwave high-temperature high vacuum furnace
The recovery melting of uranium zircaloy cutting.
Specifically, the Rapid recovery device includes heating crucible 10, muff 20 and is filled in heating crucible 10 and insulation
Set 20 between auxiliary thermosphere 30, heating crucible 10 is made up of recrystallization SiC ceramics and inner surface be coated with calcium zirconate coating to prevent
Only melting material reacts with crucible, and muff 20 is by Al2O3It is made, auxiliary thermosphere 30 is by ZrO2Particle or recrystallization SiC piece group
Into.Wherein, heating crucible 10 is used to contain and melting uranium zircaloy chip, and muff 20, which is used to realize in fusion process, to be protected
Temperature, auxiliary thermosphere 30 then plays the effect of Accelerate Crucible and uranium zircaloy chip heating.
The Rapid recovery device universality of said structure and material is stronger, with good heating and heat-insulating property, heating
Crucible 10, auxiliary thermosphere 30 and muff 20 are drawn materials easily and preparation price is relatively low, the resistance to rapid heat cycle in fusion process, safety
Property preferably, be advantageously implemented the microwave melting of metal.Wherein, the good material of heating crucible selection absorbing property, can make melting
Heating whole device at initial stage has higher heating rate；It is good using absorbing property but the heating effect of heating crucible is limited
Auxiliary thermosphere can further improve smelting efficiency；Muff may insure the heating effect of heating crucible and uranium zircaloy chip,
It requires it is not only to have had thermal insulation but also with wave, and microwave may pass through muff and act on heating crucible therein and chip
On.
Wherein, muff 20 includes sleeve 21 and top cover 22, after uranium zircaloy chip 40 is put into heating crucible 10,

Fusion process includes following sub-step：
1) control heating power increases to maximum heating power Y with Y/10~Y/4W/min speed.In this sub-step,
Heating power, which is continuously increased, can accelerate fusion process, but increase can not be too big, and otherwise device microwave reflection is more, causes power
Waste.
2) maximum heating power Y is kept, until the temperature of uranium zircaloy chip reaches TIt is molten.Wherein, maximum heating power Y
Size depends on specific melting material, when device and the timing of material one, then Y value determination.
3) after uranium zircaloy chip is completely melt, control heating power is reduced to 0.6Y~0.8Y, and insulation 10~
30min, is cooled to after room temperature to come out of the stove and obtains uranium zircaloy ingot；Preferably, with 1/2Y~Y rate reduction heating power.Protecting
During temperature, the temperature of uranium zircaloy chip is maintained at 1.05T after fusingIt is molten~1.1TIt is molten.Because absorbing property becomes after melt material
Well, it is necessary to which suitably reduction power is to prevent melt heating too high, wherein, the smelting temperature of material is general more slightly higher than the fusing point of material
Some.
Wherein, TIt is moltenFor the fusing point of uranium zircaloy chip, DEG C；Y is maximum heating power, W；Y and heating crucible internal diameter Ф1
(mm) ratio is 10:1~100:1.
In the fusion process, the three-stage load mode of power increase-stabilization-bust is employed, and when uranium zirconium is closed
When the temperature of golden chip is increased to 2/3 temperature of fusing point, its absorb microwave ability be remarkably reinforced, can be directly heated by microwave into
And obtain higher smelting efficiency and preferable Smelting Effect.Thus, the above-mentioned melting mode rate of heat addition is fast, can obviously reduce and adds
Heat uses power, will reduce more than half the time required to melting, therefore can reduce the waste of the energy and reduce uranium zircaloy chip
The pollution caused in removal process.
Preferably, in the step of chip is cleaned, using buck, trichloro ethylene, alcohol three passage cleaning ways to uranium
Zircaloy chip is cleaned and is pressed into uranium zircaloy chip group after the chip of uranium zircaloy is dried after the washing.Wherein, alkali
The NaOH aqueous solution of dilution may be selected in water.
In the step of shove charge, uranium zircaloy chip group is fitted into the heating crucible 10 of Rapid recovery device, will be quick
Retracting device is put into microwave high-temperature high vacuum furnace (not shown), is vacuumized after closing stove and (is utilized vavuum pump) to vacuum and reach 5
×10-2More than Pa.
In the step of coming out of the stove, after uranium zircaloy ingot is cooled to room temperature, it is passed through dry clean air (unlatching vent valve) and treats
Vacuum is less than 5 × 103Vacuumized again after Pa, being passed through dry clean air again after vacuum reaches 10~100Pa, (unlatching is put
Air valve), uranium zircaloy ingot is taken out in blow-on after so repeatedly 2~5 times.Because uranium zircaloy has in radioactivity, melting rear hearth
With the presence of harmful substance, take out to go divided by avoid to produce people during blow-on by the harmful substance in stove after vacuum several times repeatedly and injure.
It should be understood that above-mentioned embodiment and following examples that the utility model is described in detail be merely to illustrate the utility model and
Be not used in limitation scope of the present utility model, those skilled in the art made according to the above of the present utility model some
