Description
Technical field
The utility model belongs to metal recovery field, is related to titanium alloy recovery vacuum consumable smelting stove, and in particular to a kind of
From feed formula Ti-6AL-4V blocks recovery vacuum consumable smelting stove.
Background technology
The nominal chemical composition that Ti-6Al-4V is titanium alloy trade mark TC4 is expressed, its main component：Al：5.5%-
6.75%, V：3.5%-4.5%, surplus Ti.Due to its heat resistance, intensity, plasticity, toughness, formability, solderability, resistance to
Corrosion and biocompatibility are preferable, and as the trump alloy in titanium alloy industry, the alloy usage amount has accounted for whole titaniums and closed
The 75%~85% of gold.Yet with the processing characteristic of titanium alloy, complex manufacturing, work flow length, yield rate is low to be caused
The block maimed material of a large amount of titanium alloys can be produced in process, therefore is reapplied after deploying recycling to it, with regard to section can be reached
About resource, reduce the purpose of cost.
Current TC4 titanium alloy recovery methods are divided into seven steps：1st, the block of recovery is welded into electrode；2nd, the electricity that will be welded
Welded with auxiliary electrode pole；3rd, the melting in consumable electrode vacuum furnace by the electrode being welded, an ingot is made；4th, melting polylith is repeated
Ingot；5th, by a several ingot butt welding, then weld on auxiliary electrode, second of continuation, come out of the stove as secondary ingot；6th, the is repeated
5 steps, reach quality of finished until going out ingot；7th, strip off the skin sampling after cooling down.
Traditional TC4 titanium alloys recovery method does not carry out Effective selection, and block alloy examination is not in place, is mixed with other boards
Number alloy block, cause to reclaim ingot casting off analysis；Numerous solder joints are had when block is welded into electrode, this can be deposited to changing ingot
Greatly endangering；And it is only that block is simply welded with tungsten argon arc welding method, this welding method can cause titanium
It is miscellaneous that alloy pig contains tungsten clip, and because block is surface-treated not in place, low-density element N, O be present and be mingled with；Reclaim process
In not only need multiple welding recovery block and electrode, also need to remove consumable electrode vacuum furnace and electrode therein with block ingot progress multistep
The operation such as fortune, efficiency is low, and with certain risk, easily causes semi-finished product damage, yield rate further reduces.
Retracting device used in current TC4 titanium alloys is relatively simple, as shown in Fig. 2 conventional conventional vacuum consumable melts
Using electrode stem and female electrode as core, periphery parcel is reclaimed in process, it is necessary to repeatedly will furnace with vacuum system and furnace shell
Titanium alloy block ingot and female electrode welding, an ingot are directly welded to one another with female electrode welding and an ingot, produce multiple solder joints,
Have a negative impact to changing ingot, have a strong impact on the quality of finished product, improve percent defective.
Utility model content
For above technical problem, this is using new goal of the invention：There is provided a kind of from feed formula Ti-6AL-4V blocks

Top opposite side access charging gear (10), charging gear (10) top set closure (9), bottom installation feed hopper
(11) first, is provided with the feed hopper to material for making clothes storehouse (111), second to material for making clothes storehouse (112), the 3rd to material for making clothes storehouse (113)
Material for making clothes storehouse (114) are given with the 4th, described first gives material for making clothes storehouse (113) to material for making clothes storehouse (111), second to material for making clothes storehouse (112), the 3rd
Magnetic valve is installed to material for making clothes storehouse (114) bottom with the 4th.
Further, as improvement of the present utility model, it is characterised in that：Described first gives to material for making clothes storehouse (111), second
Material for making clothes storehouse (112), the 3rd are cylinder to material for making clothes storehouse (114) to material for making clothes storehouse (113) and the 4th.
The utility model takes above technical scheme, when reclaiming TC4 titanium alloy blocks, is first spread in water-cooled red copper crucible bottom
Upper 100kg blocks, and respectively add 100kg blocks in 4 feed hoppers in charging gear.The rear starting the arc is vacuumized first to melt, will
The block of water-cooled red copper crucible bottom is melted, and is then opened first by magnetic valve and is given material for making clothes storehouse, is dropped naturally furnace chamber in block
After interior, continue the starting the arc and melt, the block that its complete excess-three of melting is given in material for making clothes storehouse by that analogy.
By above step, the step of welding block to electrode is not only eliminated, while eliminates one defective material of welding and block
The process of material, solder joint caused by welding, improves quality and yield rate when greatly reducing recovery TC4 titanium alloy blocks.Meanwhile
During process operation, 5 pieces of blocks are disposably added, reduce operational sequence, blow-on number is reduced, saves intermediate steps and take out again
The process of vacuum, operating efficiency is improved, reduce consumption.
