Abstract
A kind of anti-oxidant, anti-corrosion, resistant to high temperature hafnium alloy processing technology of one kind being related to hafnium alloy processing technique field, the technique is as follows: hafnium alloy slab ingot is placed on to the position that tup is corresponded in processing machine by big manipulator, then tup forges and presses hafnium alloy slab ingot with the speed decline of 1min150~170mm, after a face of hafnium alloy slab ingot has been forged, hafnium alloy slab ingot is removed and is heated to 460 ± 10 DEG C, then it turns out again, another face of hafnium alloy slab ingot is forged and pressed, until the face has been forged；It repeats the above steps, until the thickness for being machined to need by hafnium alloy slab ingot；The technique can effectively improve the machining yield of hafnium alloy slab ingot.
Description
Technical field
The present invention relates to hafnium alloy processing technique fields, more particularly, to a kind of adding applied to high-melting-point hafnium alloy slab ingot
Work technique.
Background technique
It is well known, since hafnium alloy not only has good corrosion-resistant, room temperature mechanics and higher stretching and compression yield
Fusing point, but also there is high-temperature instantaneous fusing point and good forming and welding performance, and use temperature≤150 DEG C, therefore, lead to
It is usually used in making aircraft skin, hatch door, siding, stringer, the rocker arm of operating system, support, guided missile covering and aerospace structural member etc.；
But in practical applications, the density and fusing point of hafnium alloy are improved by processing due to needs, and the process processed mostly is
Carry out decision by the personal experience of Field Force, therefore, the machining yield of existing high-melting-point hafnium alloy slab ingot is very low.
Summary of the invention
In order to overcome the shortcomings in the background art, the invention discloses a kind of hafnium alloys anti-oxidant, anti-corrosion, resistant to high temperature to add
Work technique, the technique can effectively improve the machining yield of hafnium alloy slab ingot.
For achieving the above object, the present invention adopts the following technical scheme:
A kind of anti-oxidant, anti-corrosion, resistant to high temperature hafnium alloy processing technology, the processing step are as follows:
(1) high-melting-point steel plate matched with the size of hafnium alloy slab ingot, weight is lived by a big manipulator clamping, and by one
Deblocking temperature is that 1000 DEG C of steel ingot is placed on steel plate folded by big manipulator, is then put high temperature steel ingot to adding using big manipulator
Below the tup of work machine, at this point, corresponding drop to above high temperature steel ingot of tup is preheated；When the temperature of tup reaches 300 DEG C
When, rise tup, while quickly removing big manipulator, and high temperature steel ingot is quickly removed；
(2) the hafnium alloy slab ingot after being heated up by a gadget hand handle moves on on the steel plate of big manipulator, it is desirable that hafnium alloy
The upper and lower surface of slab ingot makes of carbon dust to be lubricated, while requiring to place hafnium alloy slab ingot at once when removing high temperature steel ingot；
(3) face forging and stamping of hafnium alloy slab ingot finish, and are heated to 460 ± 10 DEG C after hafnium alloy slab ingot is removed, then
It turns out again, another face of hafnium alloy slab ingot is forged and pressed, until the face has been forged；
It is of the present invention to process the simple for process of hafnium alloy slab ingot, it is convenient for enforcement of regulations, using the technique
High-melting-point hafnium alloy slab ingot is processed, is not only able to effectively improve machining yield, but also can be due to the raising of yield rate
The corresponding cost for reducing high-melting-point hafnium alloy, and then achieved the purpose that increase high-melting-point hafnium alloy occupation rate of market.
Specific embodiment
The present invention can be explained in more detail by the following examples, the open purpose of the present invention is intended to protect the present invention
All changes and improvements in range, the invention is not limited to the following examples:
The processing step of processing hafnium alloy slab ingot of the present invention is as follows:
(1) processing machine for selecting 7000 tons is lived mating with size, the weight of hafnium alloy slab ingot by a big manipulator clamping
High-melting-point steel plate, and be that 1000 DEG C of steel ingot is placed on steel plate folded by big manipulator by a deblocking temperature, then utilize big machine
Tool hand puts high temperature steel ingot to the tup of processing machine, at this point, corresponding drop to above high temperature steel ingot of tup is preheated；When
When the temperature of tup reaches 300 DEG C, rise tup, while quickly removing big manipulator, and high temperature steel ingot is quickly removed；
(2) the hafnium alloy slab ingot after being heated up by a gadget hand handle moves on on the steel plate of big manipulator, as needed,
The upper side of hafnium alloy slab ingot places heat preservation asbestos cloth, too fast to prevent its temperature from declining；Furthermore, it is desirable that hafnium alloy slab ingot
Upper and lower surface makes of carbon dust to be lubricated, while requiring to place hafnium alloy slab ingot at once when removing high temperature steel ingot；Move on the steel plate
Inaccurate having time is poor when walking high temperature steel ingot and placing hafnium alloy slab ingot；
(3) face forging and stamping of hafnium alloy slab ingot finish, and hafnium alloy slab ingot are first heated to 460 ± 10 DEG C, then again
It turns out, another face of hafnium alloy slab ingot is forged and pressed, until this face of hafnium alloy slab ingot has also been forged；
Implement to need to pay attention to when the technique of the processing hafnium alloy slab ingot:
(1) in processing, a face of hafnium alloy slab ingot is once merely able to processing together, that is, it is same to be unable to Continuous maching
Face twice, when a face processes one, will turn out reprocessing together, if how flat heating time processing two, hafnium close
Ingot is easy for cracking, this is because the crystal size of hafnium alloy slab ingot the inside after forging together is different, which is easy to crack
Mixed crystal, therefore cannot be to a Mian Duan bis- of hafnium alloy slab ingot；There are one the reason is that at a temperature of hafnium alloy slab ingot
Drop is very fast, is easy for cracking when at a temperature below 380 DEG C；It processes first, it is anti-a to forging when hafnium alloy forging heats
Face reheats, because forging is obtained and processed on the other surface when forging second.
(2) tup of processing machine used in is a U-shaped, i.e., using the arc edge of tup come the conjunction of effective guarantee hafnium
Golden slab ingot can have certain mobility in processing；
(3) the primary processing capacity of processing machine should be the 25~29% of hafnium alloy slab ingot thickness, and certain it is noted that being every time
It is no forging thoroughly because once forge it is impermeable if, lower road process when be easy for cracking.
Part not in the detailed description of the invention is the prior art, therefore the present invention is not described in detail.
