2, hot-stretch; Low temperature large working modulus rolling fast should be taked during the ingot casting hot-stretch of red copper class, reduce high-temperature oxydation as far as possible.
3, cold stretch; Red copper plasticity is good, and the cold working rate between twice annealing can reach more than 95%.Therefore general in cold stretch process without the need to intermediate annealing.
4, finished products; Red copper is oxidizable when annealing, and therefore need carry out in the annealing furnace of protective atmosphere.
5, cleaning and finishing; Red copper alloy wire belt surface is easy to change, should carry out in time cleaning, passivation.Red copper is relatively soft, and should take measures (as lining paper) prevents from wiping and scratch.Carefully to adjust the thrust of cutter during shearing, prevent impression.
The present invention has following beneficial effect: technological process is simple, easy to operate, smart stretching process is flattened by continuous print hot-stretch, mutually realized by annealing, aligning and the operation of milling face is carried out additionally by aligning milling face, by last finishing machine carries out retrofit operation, obtain fine copper alloy wire finished product; The packaging that is finally up to the standards warehouse-in.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
