Abstract
The invention discloses zinc white wire rod to resist disconnected processing technology, its step is：Horizontal casting → cold rolling → hypoxemia annealing → drawing plane → line falling → hypoxemia annealing → Diluted Acid Washing → more closing mould stretching → bell-type annealing → test packages；Wherein, casting temperature l000~1150 DEG C; 0.8~1.6 m/min of casting speed, pickling use concentration as 15~20% dilution heat of sulfuric acid, 50~65 DEG C of pickling temperature; annealing adds nitrogen and makees protection gas; annealing temperature is 385~410 DEG C, and soaking time 90~120 minutes, carries out line falling operation; the end of a thread that will bear against the innermost upper procedure of winding roll is poured out, the end of a thread as lower one of stretching process.The beneficial effects of the invention are as follows：（1）The present invention uses simple tension method, and from the beginning unidirectional every time to draw, the threadiness inside alloy forms smooth；With the increase of processing passage, the proportional increase of quantity of fiber line, inorganization disorder phenomenon, the excellent physical properties of product；（2）The present invention use parabola heating and cooling technique, often reduction by one temperature gradient with regard to constant temperature for a period of time, the alloy crystalline phase being achieved in that uniformly is interlocked, without through check.
Description
Technical field
The present invention relates to wire rod manufacture field, more particularly to a kind of zinc white wire rod to resist disconnected processing technology.
Background technology
Since the selection of electron emitting cathode material belongs to high temperature refractory, in this way, alloy stretching and it is annealed
There are following defect in journey：1) when drawing, since tungsten-bast alloy wire rod needs to carry out multi-drawing operation, such tungsten-bast alloy line
Material end to end will be by Repeated Compression, the later stage produces cellulose disturbance state (such as dovetail shaped), serious shadow easily inside alloy
Ring the physical property of product；2) it is main at present to be moved back using the rapid temperature rise and drop of VTOL function in order to shorten process time when annealing
Fire, during short annealing, alloy interior tissue recrystal grain, which is grown up rapidly, to be run through, and causes alloy material intensity low, forming process
In there are product risk of breakage.
The content of the invention
The purpose of the present invention is a kind of zinc white wire rod provided the defects of the customer service prior art resists disconnected processing technology.
The technical solution adopted by the present invention is：A kind of zinc white wire rod resists disconnected processing technology, its step is：Horizontal casting → cold
Roll → hypoxemia annealing → drawing plane → line falling → hypoxemia annealing → Diluted Acid Washing → more closing mould stretching → bell-type annealing → test packages；Its
In, casting temperature l000~1150 DEG C, 0.8~1.6 m/min of casting speed, pickling use concentration for 15~20% dilute sulphur
Acid solution, 50~65 DEG C of pickling temperature, annealing add nitrogen and make protection gas, and annealing temperature is 385~410 DEG C, soaking time 90
~120 minutes, line falling operation is carried out, the end of a thread that will bear against the innermost upper procedure of winding roll is poured out, and is drawn together as lower
Stretch the end of a thread of process.
As a further improvement on the present invention, made annealing treatment using parabola heating and cooling technique, temperature lowering curve is in throwing
Thing wire, and a temperature gradient is often reduced with regard to constant temperature 13-23 minute, terminate until annealing.
As a further improvement on the present invention, the temperature gradient is 50 DEG C, and constant temperature time is 30 minutes.
The beneficial effects of the invention are as follows：（1）The present invention uses simple tension method, from the beginning unidirectional every time to draw, inside alloy
Threadiness formed it is smooth；With the increase of processing passage, the proportional increase of quantity of fiber line, inorganization disorder phenomenon, production
The excellent physical properties of product；（2）The present invention use parabola heating and cooling technique, when often one temperature gradient of reduction is with regard to one section of constant temperature
Between, the alloy crystalline phase being achieved in that uniformly is interlocked, without through check.
