Description
Technical field
The present invention relates to a kind of copper post anaerobic annealing process.
Background technique
Copper post is the element for measuring various weapon gun pressures, it is the core element of Cu atomic weight.It is passed through by copper ingot
It draws to dial repeatedly and copper wire is made, then made of vehicle system, copper post should have good surface quality, and deform uniform.Copper cylinder has
Taper copper post and two kinds of cylindricality copper post.Copper post annealing is one of very important process, the purpose of annealing in copper post process
It is to eliminate copper wire in order to refine grain structure and draw the internal stress dialled and generated in copper post mechanical processing process repeatedly.Copper post annealing
With copper cylinder or the box-packed Sheng copper post of copper, auxiliary material has asbestos board, asbestos cord, waterglass, gasoline, alcohol, copper sheet, red copper bits etc..For
Copper post is prevented to be oxidized in annealing, when copper post is packed into copper cylinder (copper box), red copper bits are filled up in the space for being underfilled with copper post,
And separated copper post and red copper bits with copper sheet, asbestos board, finally it is sealed with asbestos cord and waterglass.When poorly sealed or
Person puts when having large quantity of air in cylinder after copper post, and in annealing, with copper scale, copper post oxidation reaction will occur for the oxygen in air,
It generates copper oxide and causes scrapping for copper post so that there is oxidized streak on copper post surface.
Summary of the invention
It is an object of the invention to: it is oxidized when one kind being provided, copper post annealing can be effectively prevented, reduces copper post scrappage
Copper post anaerobic annealing process.
Present invention process includes following work step: cleaning copper post gasoline before annealing and dries；Copper post is packed into copper cylinder；It will
Copper cylinder is put into electric furnace, shuts fire door；It is made annealing treatment；Copper cylinder is come out of the stove, and copper cylinder is put into sink, cooling with flowing cool water
Afterwards, copper post is taken out；It is characterized by: filling up pig scrap in copper cylinder after copper post is packed into copper cylinder.
When the present invention makes annealing treatment, for heating temperature between 450 DEG C~650 DEG C, soaking time is 100 minutes~200
Minute.
When the present invention makes annealing treatment, for heating temperature between 500 DEG C~600 DEG C, soaking time is 120 minutes~160 points
Clock.
Present invention process is oxidized when copper post annealing can be effectively prevented, and reduces the scrappage of copper post, reduces production cost,
And it is simple process, safe and reliable.
Specific embodiment
The present invention is described in detail with reference to embodiments.
The annealing operation of copper post is divided into five work steps and carries out:
It is dried 1. cleaning copper post gasoline before annealing.
2. copper post is packed into copper cylinder (copper box).
3. copper cylinder (copper box) is put into electric furnace, fire door is shut.
4. being made annealing treatment, for heating temperature between 450 DEG C~650 DEG C, soaking time is 100 minutes~200 minutes,
And it makes a record.
5. bronze medal cylinder (copper box) is come out of the stove, copper cylinder (copper box) is put into sink, after flowing cool water cooling, takes out copper post.
The invention is in work step 2 different from original process.After installing copper post, copper post is underfilled in copper cylinder (copper box)
Space fill up pig scrap, with pig scrap instead of red copper consider to be worth doing；Because iron is the active metal of comparison, its movable metallic ratio
Copper is strong, and when having large quantity of air in poorly sealed or cylinder, at high temperature, oxidation reaction will occur with the oxygen in air for iron, raw
At iron oxide, the oxygen in air is consumed, and the activity of copper is weaker, and oxidation reaction will not occur with oxygen, to protect copper post.
Embodiment 1:
First copper post gasoline is cleaned and is dried, then copper post is packed into copper cylinder (copper box), is underfilled with copper post in copper cylinder (copper box)
Pig scrap is filled up in space, and copper cylinder (copper box) is put into electric furnace, fire door is shut.Made annealing treatment, heating temperature 450 DEG C~
Between 650 DEG C, soaking time is 100 minutes~200 minutes, and is made a record.Copper cylinder (copper box) is come out of the stove, and copper cylinder (copper box) is put
Enter in sink, after flowing cool water cooling, takes out copper post.
Embodiment 2:
It is made annealing treatment, heating temperature is between 500 DEG C~600 DEG C, and soaking time is 120 minutes~180 minutes, Qi Tagong
It walks same as Example 1.
Embodiment 3:
It is made annealing treatment, heating temperature is between 550 DEG C~600 DEG C, and soaking time is 130 minutes~160 minutes, Qi Tagong
It walks same as Example 1.
Embodiment 4:
When annealing, for heating temperature between 500 DEG C~600 DEG C, soaking time is 120 minutes~160 minutes.Other work steps
It is same as Example 1.
Through practical proof: after replacing pig scrap red copper to consider to be worth doing, having carried out copper post annealing test 50 times, do not found 1
Example copper post is oxidized phenomenon.
What has been described above is only a preferred embodiment of the present invention, it is noted that for those skilled in the art,
Without departing from the structure of the invention, several modifications and improvements can also be made, these also should be considered as guarantor of the invention
Range is protected, these all will not influence the effect and patent practicability that the present invention is implemented.
