Description
Technical field
A kind of method for annealing the present invention relates to welding with Alar bar.
Background technology
With the development of welding technique, aluminium and Welded structure are widely used to civilian and military industry field, such as each
Kind of pressure vessels for the chemical industry, the vehicles, naval vessel, aircraft, rocket, space probe etc., and bullet train, subway train, city are light
Rail is the industry that state key investment is supported to help.These welded performances, in the case where base material is certain, mainly depend on
In welding procedure and the alloying component and performance of welding wire.Wherein, welding wire is to influence weld metal component, tissue, liquid-solid phase line temperature
An important factor for degree, the hot crackability of Jin Feng areas mother metal, the corrosion resistance of weld seam and mechanical property.Therefore, solder wire material closes aluminium
The welded extensive use of gold is of great significance.
Mainly to control based on intensity index in alusil alloy bar production process, due to subsequently by rod of metal alloy production alloy weldering
Using the mode of production of multimode drawing, it is necessary to be eliminated by annealing inside rod of metal alloy since processing hardening causes during silk
Stress constantly strengthen, so as to improve the plasticity of rod of metal alloy, reduce resistance of deformation, the elongation index obtained, makes alloy
The tissue and performance of bar are improved.It cannot not only reach without rational alusil alloy bar annealing process and processing is completely eliminated firmly
The purpose of stress caused by change, and constantly raised by multi pass drawing, the intensity of B alloy wire in follow-up drawing process, meeting
Occur the problems such as inadequate pulling capacity, drawing broken string, mould Fast Wearing in drawing process, seriously affect follow-up drawing procedure.
CN201310532828.7 discloses a kind of preparation method of soldering alusil alloy seamless flux-cored wire, line base
Production is using extrusion, and production efficiency is relatively low, and whole production process passes through 6 heating anneals, and production cost is high.
The content of the invention
The technical problem to be solved in the present invention is overcome the defects of existing, there is provided a kind of to weld with Alar bar
Method for annealing.
In order to solve the above technical problem, the present invention provides following technical solution：
A kind of method for annealing welded with Alar bar, by weight, the component of the rod of metal alloy is：Si 4-7%,
Fe≤0.4%, Cu≤0.4%, Mn≤0.4%, V≤0.4%, Mg≤0.4%, Ti≤0.4%, surplus are aluminium, and the annealing is included such as
Lower step：
（1）Black furnace feeds, then interior when 4-6 is small, and 410-430 DEG C, when insulation 4.5-5.5 is small is risen by room temperature；
（2）By step（1）Interior when 5-6 is small after processing, temperature is down to 140-160 DEG C, when insulation 2.8-3.2 is small；
（3）Through step（2）After processing, come out of the stove, is air-cooled.
Stress caused by the method for annealing of the present invention can effectively eliminate processing hardening, improves the plasticity of rod of metal alloy, reduces and become
Shape drag, the elongation index obtained, avoids drawing process interrupt line, mitigates die wear.
