Abstract
The invention discloses a copper cylinder anaerobic annealing process. The copper cylinder anaerobic annealing process includes the following steps that a copper cylinder is washed through gasoline and dried before annealing; the copper cylinder is installed in a copper tank; the copper tank is placed in an electric furnace, and a furnace door is closed; annealing treatment is conducted; and the copper tank is taken out of the furnace and placed in a water tank to be cooled with flowing cold water, and then the copper cylinder is taken out. The copper cylinder anaerobic annealing process is characterized in that after the copper cylinder is installed in the copper tank, the copper tank is filled with pig iron filings. During annealing, the heating temperature ranges from 450 DEG C to 650 DEG C, and the temperature preservation time ranges from 100 min to 200 min. By means of the copper cylinder anaerobic annealing process, the copper cylinder can be effectively prevented from being oxidized in the annealing process, the rejection rate of the copper cylinder is decreased, production cost is lowered, and the process is simple, safe and reliable.
Description
Technical field
The present invention relates to a kind of copper post anaerobic annealing process.
Background technology
Copper post is used to the element measuring various weapon gun pressure, and it is the core parts of Cu atomic weight.It makes copper cash, then car system by copper ingot through repeatedly drawing to dial, and copper post should have good surface quality, and distortion evenly.Copper cylinder has taper copper post and two kinds, cylindricality copper post.The annealing of copper post is one very important operation in the copper post course of processing, and the object of annealing is in order to crystal grain thinning tissue, eliminates copper cash and repeatedly draws the internal stress dialled and produce in copper post mechanical processing process.Copper post annealing copper cylinder or copper box-packed Sheng copper post, auxiliary material has asbestos plate, asbestos twine, water glass, gasoline, alcohol, copper sheet, red copper bits etc.In order to prevent copper post oxidized when annealing, when copper post is loaded copper cylinder (copper box), red copper bits are filled up in the space of not filling copper post, and copper post and red copper bits are separated with copper sheet, asbestos plate, finally seal with asbestos twine and water glass.When poorly sealed or when having large quantity of air after putting copper post in cylinder, when annealing, the oxygen in air will with copper scale, copper post generation oxidizing reaction, generate cupric oxide, make copper post surface have oxidized streak, cause scrapping of copper post.
Summary of the invention
The object of the invention is to: oxidized when providing one can effectively prevent copper post from annealing, reduce the copper post anaerobic annealing process of copper post condemnation factor.
Present invention process comprises following work step: cleaned by copper post gasoline before annealing and dry; Copper post is loaded in copper cylinder; Copper cylinder is put into electric furnace, shuts fire door; Carry out anneal; Copper cylinder is come out of the stove, and copper cylinder is put into tank, after flowing cool water cooling, takes out copper post; It is characterized in that: copper post fills up pig scrap after loading copper cylinder in copper cylinder.
During anneal of the present invention, Heating temperature is between 450 DEG C ~ 650 DEG C, and soaking time is 100 minutes ~ 200
Minute.
During anneal of the present invention, Heating temperature is between 500 DEG C ~ 600 DEG C, and soaking time is 120 minutes ~ 160 minutes.
Oxidized when present invention process can effectively prevent copper post from annealing, reduce the condemnation factor of copper post, reduce production cost, and technique is simple, safe and reliable.
Embodiment
Below in conjunction with embodiment, the present invention is described in detail.
The annealing operation of copper post is divided into five work steps and carries out:
1. before annealing, copper post gasoline is cleaned and dry.
2. copper post is loaded in copper cylinder (copper box).
3. copper cylinder (copper box) is put into electric furnace, shut fire door.
4. carry out anneal, Heating temperature is between 450 DEG C ~ 650 DEG C, and soaking time is 100 minutes ~ 200 minutes, and makes a record.
5. copper cylinder (copper box) is come out of the stove, and copper cylinder (copper box) is put into tank, after flowing cool water cooling, takes out copper post.
What the invention was different from former technique is in work step 2.After installing copper post, pig scrap is filled up in the space of not filling copper post in copper cylinder (copper box), instead of red copper bits with pig scrap; Because iron is more active metal; its movable metallic is stronger than copper; when there being large quantity of air in poorly sealed or cylinder; at high temperature, iron with the oxygen generation oxidizing reaction in air, will generate ferric oxide; consume the oxygen in air; and the reactivity of copper is more weak, can not with oxygen generation oxidizing reaction, thus protection copper post.
Embodiment 1:
First cleaned by copper post gasoline and dry, then loaded in copper cylinder (copper box) by copper post, pig scrap is filled up in the space of not filling copper post in copper cylinder (copper box), copper cylinder (copper box) is put into electric furnace, shuts fire door.Carry out anneal, Heating temperature is between 450 DEG C ~ 650 DEG C, and soaking time is 100 minutes ~ 200 minutes, and makes a record.Copper cylinder (copper box) is come out of the stove, and copper cylinder (copper box) is put into tank, after flowing cool water cooling, takes out copper post.
Embodiment 2:
Carry out anneal, Heating temperature is between 500 DEG C ~ 600 DEG C, and soaking time is 120 minutes ~ 180 minutes, and other work step is identical with embodiment 1.
Embodiment 3:
Carry out anneal, Heating temperature is between 550 DEG C ~ 600 DEG C, and soaking time is 130 minutes ~ 160 minutes, and other work step is identical with embodiment 1.
Embodiment 4:
During anneal, Heating temperature is between 500 DEG C ~ 600 DEG C, and soaking time is 120 minutes ~ 160 minutes.Other work step is identical with embodiment 1.
Through practical proof: after pig scrap being replaced red copper bits, carried out copper post annealing test 50 times, do not found the oxidized phenomenon of 1 routine copper post.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; under the prerequisite not departing from structure of the present invention; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
