Abstract

The invention relates to a process for drawing a flat wire of precise alloy. The process comprises the following steps of: round wire inspecting, cold rolling, deoiling and finished product treating, wherein the round wire with phi of 0.14mm is directly rolled into a finished product with the size of 0.06*0.26mm by adopting an imported online flat wire rolling mill; a cold rolling die made of a hard alloy roll has high hardness, good surface smoothness and long service life; in the deoiling step, the surface is deoiled by adopting an own prepared cleaning agent, and annealing treatment in an ammonia protective atmosphere is adopted in the finished product treatment; and in the hot treatment process of the finished product treatment, the specification of the flat wire is 0.06*0.26mm, the treatment temperature is between 950 and 1,050 DEG C, and the number of take-up revolutions is 70 to 80 revolution/minute. The process is reasonable, is convenient for use, and is suitable for production of aircraft grade precise alloy 6j20 flat wires.

Description

The flat filament drawing process of Precise Alloy
Technical field
The invention belongs to alloy cold-drawn manufacture field, relate to a kind of flat filament drawing process of Precise Alloy, be particularly suited for aviation-grade Precise Alloy 6j20 Flat Yarn Production.
Background technology
At present, Precise Alloy 6j20 Flat Yarn Production technology is unreasonable, utilizes from Φ 0.2mm to be rolled into finished product 0.06*0.26mm three times; The shortcoming of this process route is to have increased processing cost, and the hardness of finished product 0.06*0.26mm is higher, also need increase the annealing number of times middle time if will reduce finished product hardness, thereby increase cost, has reduced production efficiency.Simultaneously, in the production process of this flat filament, use the rolling flat filament of roll of GCr15; Because the roll low price of GCr15, processing are simply, therefore, generally adopt; But production for the Precise Alloy flat filament; After the roll of employing GCr15 was rolling, the surface quality of flat filament was unstable, increased difficulty to following process.
Summary of the invention
Problem to be solved by this invention is, overcomes the deficiency of prior art, and a kind of flat filament drawing process of Precise Alloy is provided, and the processing step that employing circle silk check-cold rolling-deoil-finished product is handled is not only reasonable in design, and good processability, and crudy is good.
The present invention solves its technical problem and takes following technical scheme to realize:
According to the flat filament drawing process of a kind of Precise Alloy provided by the invention, it may further comprise the steps:
(1) circle silk check: check circle silk;
(2) cold rolling: silk Φ 0.14mm directly is rolled into finished product 0.06*0.26mm to the online flat filament milling train of employing import from the garden;
(3) deoil: adopt the cleaning agent of preparation voluntarily to carry out the surface processing of deoiling;
(4) finished product is handled: the annealing in process that adopts protection of ammonia atmosphere.
It is to take following technical scheme further to realize that the present invention solves its technical problem:
Aforesaid cold rolling mould adopts hard alloy roll.
The Technology for Heating Processing that aforesaid finished product is handled is flat filament specification 0.06*0.26mm, and treatment temperature is 950-1050 ℃, and the take-up revolution is 70-80 rev/min.
The present invention compared with prior art has significant advantage and beneficial effect:
Because the processing step that invention employing circle silk check-cold rolling-deoil-finished product is handled is not only reasonable in design, and good processability, crudy is good.Mould when cold rolling adopts hard alloy roll, and hardness is high, and surface smoothness is good, long service life.
The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is a process flow diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to the specific embodiment provided by the invention, structure, characteristic and effect thereof, specify as after.
The flat filament drawing process of a kind of Precise Alloy as shown in Figure 1, it may further comprise the steps:
(1) circle silk check: check circle silk.
(2) cold rolling: rolling Φ 0.14mm-Φ 0.06mm-0.06*0.26mm; Cold rolling mould adopts hard alloy roll.
(3) deoil: adopt the cleaning agent of preparation voluntarily to carry out the surface processing of deoiling.
(4) finished product is handled: the annealing in process that adopts protection of ammonia atmosphere.The Technology for Heating Processing that finished product is handled is flat filament specification 0.06*0.26mm, and treatment temperature is 950-1050 ℃, and the take-up revolution is 70-80 rev/min.
