Description
Technical field
The present invention relates to metal smelt vessel technical fields, and in particular to the smelting vessel of titanium or titanium alloy.
Background technology
Titanium alloy has that specific strength is high, density is small, a series of good characteristics such as corrosion-resistant, is widely used in modern industry
In, such as the fields such as bioscience, engineering in medicine, aerospace industry, the energy, ocean, war industry.But due to the fusing point of titanium
It is very active with chemical property, when melting, liquid titanium almost can with the refractory materials of all crucibles for example zirconium oxide, magnesia,
Silica and aluminium oxide react, and therefore, the crucible that its melting cannot take conventional refractory material to manufacture are caused to carry out
Vacuum induction melting.Industrial titanium or titanium alloy melting is frequently with vacuum consumable electrode electric arc skull melting and water-cooled copper at present
Crucible cools down.A thin layer " scull " is first solidified when vacuum electric-arc skull crucible melting on copper wall, plays and protects titanium liquid not by crucible
Material contamination and heat-blocking action, to form a molten bath in crucible.Due to water jacketed copper crucible cooling quickly with formed scull
Keep titanium liquid temperature field uneven, in addition titanium alloy is short in the liquid retention time so that titanium alloy casting uneven components after cast.
And water jacketed copper crucible takes away a large amount of heat.Vacuum electric-arc skull crucible melting energy consumption compared with vacuum induction melting is big, melting titanium
Alloy power consumption is 40~60kw/kg.
Additionally, due to titanium condensing temperature at 1660 ± 10 degrees Celsius, the sidewall of crucible hull-skin temperature of single layer is also very high, right
The support equipment heat resistanceheat resistant performance of crucible is higher, and production cost is big.
Invention content
In view of the defects and deficiencies of the prior art, the present invention intends to provide a kind of simple in structure, reasonable design makes
With the smelting vessel of convenient titanium or titanium alloy, it includes inner wall, and inner wall is all made of tungsten metal and is fabricated to barreled container.
Further：It further includes connection annulus, outer wall, vacuum layer；Connection annulus and outer wall are all made of tungsten made of metal
It forms, the top connection closed connection of annulus of outer wall and inner wall；Connect between annulus, outer wall and inner wall is vacuum
Layer.
Further：It further includes vacuum-pumping tube, and vacuum-pumping tube penetrates outer wall and outer end leaks out, and vacuum-pumping tube is equipped with single
To valve；Vacuum-pumping tube and check valve are that tungsten metal is made.
With the above structure, the present invention has the beneficial effect that：The smelting vessel of titanium or titanium alloy of the present invention, it is adopted
It is designed with vacuum layer, vacuum can prevent heat from being conducted, in conjunction with the feature of tungsten material thermal conductivity poor performance, the temperature of outer wall
Will not be excessively high, reduce the heat resistant requirements degree of outer wall mounting structures；It uses the inner wall design of tungsten material, and tungsten 3410 is utilized
± 20 degrees Celsius of high temperature melting point property and stability greatly reduces heat energy loss instead of water jacketed copper crucible, saves
Production cost.
Description of the drawings
Attached drawing described herein is to be used to provide further understanding of the present invention, and is constituted part of this application, but
It does not constitute improper limitations of the present invention, in the accompanying drawings：
Fig. 1 is schematic structural view of the invention；
Reference sign：
1- connections annulus, 2- outer walls, 3- vacuum layers, 4- inner walls, 5- vacuum-pumping tubes, 6- check valves.
Specific implementation mode
Come that the present invention will be described in detail below in conjunction with attached drawing and specific embodiment, illustrative examples therein and says
It is bright to be only used for explaining the present invention but not as a limitation of the invention.
As shown in Figure 1, the smelting vessel of the titanium or titanium alloy described in present embodiment, it includes inner wall 4, inner wall 4
Barreled container is fabricated to using tungsten metal.
Further：It further includes connection annulus 1, outer wall 2, vacuum layer 3；Connection annulus 1 and outer wall 2 are all made of tungsten gold
Category is made, the top connection 1 closed connection of annulus of outer wall 2 and inner wall 4；Connect annulus 1, outer wall 2 and inner wall 4 it
Between be vacuum layer；The design of double wall combination vacuum layer further reduces the temperature of 2 outer surface of outer wall, reduces support knot
The temperature requirement of structure.
Further：It further includes vacuum-pumping tube 5, and vacuum-pumping tube 5 penetrates outer wall 2 and outer end leaks out, and is set on vacuum-pumping tube 5
There is check valve 6；Vacuum-pumping tube and check valve are that tungsten metal is made；The design of vacuum-pumping tube 5 reduces smelting vessel
Manufacture difficulty after being welded with tungsten electrode between connection annulus 1, outer wall 2 and inner wall 4 under general environment take out very
It manages in vacancy..
The smelting vessel of titanium or titanium alloy of the present invention, its operation principle are：Smelting of the inner wall 4 as Titanium
Molten bath, Titanium is heated to melting at 1660 ± 10 degrees Celsius in inner wall 4, and 4 fusing point of inner wall of tungsten metal material is up to
3410 ± 20 degrees Celsius, the titanium of liquid will not cause inner wall 4 high temperature, and titanium and tungsten metal under vacuum conditions
It will not react.
The smelting vessel of titanium or titanium alloy of the present invention, it using vacuum layer design, vacuum can prevent heat into
Row conduction, in conjunction with the feature of tungsten material thermal conductivity poor performance, the temperature of outer wall will not be excessively high, reduces the resistance to of outer wall mounting structures
Heat request degree；It uses the inner wall design of tungsten material, and the high temperature melting point property and stabilization of 3410 ± 20 degrees Celsius of tungsten is utilized
Property, instead of water jacketed copper crucible, heat energy loss is greatly reduced, has saved production cost.
The above is only the better embodiment of the present invention, therefore all constructions according to described in present patent application range,
The equivalent change or modification that feature and principle are done, is included within the scope of present patent application.
