Square rod is put into pickling tube and carries out pickling processes by the 4th step；
Square rod is dialled equipment progress cold drawing processing by drawing by the 5th step；
6th step repeats the technique of the second to five step at least once；
Square rod, is stretched to the size of drawing requirement by the 7th step, then examined just, polishing treatment, through after the assay was approved, packet
Dress is transported to subsequent processing or factory carries out part cutting process.
In second step, the temperature of annealing furnace is maintained at 950~1100 DEG C, and soaking time is 1~1.5 hour.
In third step, the temperature of solution treatment is maintained at 1000~1150 DEG C, and soaking time is 1~1.5 hour；At cooling
When reason, the temperature of coolant liquid is lower than 60 DEG C.
In 4th step, before cold drawing processing, drying and processing is carried out to square rod.
Before at the square rod drying, protective layer is smeared on the surface of square rod.
After first time pickling processes, welding welding pull head is cut off on square rod after last time cold drawing processing on pole
Weld pull head.
Reconditioning processing is carried out by angle grinder to square rod after each pickling.
In step 6, the technique number for repeating the second to five step is four times.
Beneficial effects of the present invention: after using technique of the invention, because in the production process by multiple pickling
Reason, the billet surface of pull-out are highly polished；Due to passing through multiple annealing, solution treatment, the bar of pull-out has anti-well
Compressive Strength and higher hardness.Therefore, have appearance good using the mounting bracket that technique of the invention makes, compression strength and hard
Spend high advantage.
