Description
Technical field
The invention belongs to titanium alloy preparation field, be specifically related to the melting of a kind of titanium-niobium alloy ingot casting
Method.
Background technology
Titanium alloy and composite get more and more in the application of aerospace field, and as compound
The application of the titanium alloy fastener of material connector also gets more and more, and in recent years, titanium alloy fastens
Part the most successfully replaces the steel securing member that partial intensities is relatively low, obtains extraordinary weight loss effect.
The titanium-niobium alloy of annealed state is above pure titanium because of its shear strength, tensile strength, but resistance of deformation
Less than pure titanium, it is highly suitable as rivet bar.
The preparation of titanium-niobium alloy ingot casting at present is mainly by 2～3 vacuum consumable arc-meltings
Realizing, its process route is as follows: be pressed into electrode block after considering titanium sponge and niobium to be worth doing batch mixing,
After titanium sponge and niobium bar cloth, it is pressed into electrode block, then electrode block assembly welding is become from power consumption
Pole, consutrode obtains ingot casting after 2～3 vacuum consumable arc-meltings.
The fusing point of niobium is higher about 800 DEG C than titanium, uses consutrode prepared by said method in melting
During, owing to each position burn-off rate is different, easily cause ingot chemistry uniformity relatively
Difference.Further, since the density of niobium is about 2 times of titanium, the niobium not being completely melt in fusion process
Crumble easily sinks to bottom molten bath, causes niobium to be mingled with.Accordingly, it would be desirable to the one preferably side of preparation
Method improves the metallurgical quality of titanium-niobium alloy ingot casting.
Summary of the invention
It is an object of the invention to the shortcoming overcoming above-mentioned prior art, it is provided that a kind of steady quality
Property high titanium-niobium alloy ingot casting method of smelting, improve the titanium-niobium alloy ingot casting that existing technique prepares
The phenomenons such as uneven components, niobium are mingled with, improve raw material lumber recovery, reduce spillage of material.
For achieving the above object, the technical solution used in the present invention is:
The method of smelting of a kind of titanium-niobium alloy ingot casting, comprises the following steps:
Step 1: if if Heavenly Stems and Earthly Branches titanium rod and Heavenly Stems and Earthly Branches niobium rod being welded into consutrode；Wherein, one
The surrounding of titanium rod uniformly arrange a circle niobium rod, and the surrounding of niobium rod the most uniformly arrange one, and to enclose titanium excellent,
Niobium rod and titanium rod are all placed in parallel；
Step 2: melting once, obtains one by consutrode melting in vacuum consumable electrode arc furnace
Secondary ingot；Wherein, melting electric current is 6-10KA, and melting voltage is 27-30V；
Step 3: secondary smelting, is inverted an ingot as consutrode at vacuum consumable electric arc
Carrying out secondary smelting in stove and obtain secondary ingot, melting electric current is 7-12KA, and melting voltage is
29-34V；
Step 4: three meltings, is inverted secondary ingot as consutrode at vacuum consumable electric arc
Carrying out three meltings in stove and obtain three ingots, melting electric current is 7-10KA, and melting voltage is
30-35V；
Step 5: cooling, melting is cooled to less than 200 DEG C and comes out of the stove after completing, obtain titanium niobium and close
Gold ingot casting；Wherein, percentage in this alloy cast ingot, content of niobium is 46.8～55%,
Surplus is titanium.
Described titanium rod, the purity of niobium rod are all higher than equal to 99.8%.
Described titanium rod, the length that niobium is excellent are identical；Wherein it is positioned at the excellent and all niobium of a titanium at center
The diameter of rod is identical, and the diameter of remaining titanium rod is not more than the diameter of niobium rod.
Described welding uses plasma arc soldering method to weld.
Compared with prior art, beneficial effects of the present invention is as follows:
1) this invention simplifies technique, eliminate and prepare niobium bits, niobium bar and electrode pressing block
Step.
2) in the present invention, consutrode uses the titanium rod of whole, niobium rod is prepared from, in melting
During, titanium rod, niobium rod just can fall in molten bath after being completely melt, it is to avoid niobium folder in melting
Miscellaneous generation.
3) chemical composition of the titanium-niobium alloy ingot casting that prepared by the present invention is uniform, stable, its chemistry
Composition tolerances is less than 0.2%, and segregation-free and high density are mingled with metallurgical imperfection.The present invention is applicable to
The titanium-niobium alloy ingot casting that production metallurgy quality is high.
Further, in the present invention, titanium length excellent, niobium rod is identical；Wherein it is positioned at the one of center
The diameter propping up titanium excellent and all niobium rod is identical, and the diameter of remaining titanium rod is not more than the diameter of niobium rod.
In fusion process, arc column middle part temperature is higher, and arc column lip temperature is relatively low, in the present invention certainly
Niobium rod is welded in consutrode middle part by power pole welding mode, and titanium rod is welded in outside consutrode
Surface, reduces because burn-off rate difference causes ingot casting uneven components, even if it addition, titanium rod melts
Changing speed and be faster than niobium rod, titanium rod melts prior to niobium rod, but because titanium rod, niobium rod are closely knit material,
When only waiting the niobium rod on consutrode to be completely melt to be in same plane with titanium rod, the just meeting of titanium rod
Again melt, reduce further the burn-off rate impact on ingot casting chemistry uniformly property.
