Description
Technical field
The present invention relates to field of metal preparation, more particularly to a kind of preparation method of magnesium alloy solder wire.
Background technology
Because magnesium alloy density is low, fusing point is low, and thermal conductivity and electrical conductivity are big, and thermal coefficient of expansion is big, and chemical activity is strong, easily
Oxidation, and the fusing point of oxide is very high, makes magnesium alloy that coarse-grain, oxidation and evaporation, thermal stress, weld seam can be produced in welding process
Stay, a series of difficulty such as stomata, fire check.When welding magnesium alloy using welding with filler wire method, the mechanical property of welding point
Can be not only relevant with welding condition, also the composition with welding wire has much relations.
Welding is a kind of important manufacturing process to form structural member.Magnesium alloy is used as a kind of novel high-performance structural wood
Material, will necessarily use welding structure in actual applications.At present, the welding wire needed for the welding process of domestic magnesium alloy mainly leads to
Cross two methods of casting and the production of hot extrusion.
Magnesium alloy belongs to Patterns for Close-Packed Hexagonal Crystal structure, at room temperature only 3 slip systems, and its plastic deformation needs more
Sliding and twin coordination are depended on, and is finally limited by the lattice parameter of twin magnesium than c/a=1.6235, in stretching
Under stress, the inside of crystal will not occur twinning deformation, therefore the comparing that magnesium and its alloy are showed in stretching is crisp, plasticity
Difference, generally less than 10%.In a compressed state there is twinning deformation in crystals, due to crystals sliding and twin association
Adjust, magnesium and its alloy can show good plastic deformation ability when pressure is born, so extruding, forging, rolling and punching press
Etc. the Plastic Forming for being suitable for magnesium alloy.
Therefore, magnesium alloy only welding wire is in most cases produced with hot extrusion method.Generally, can be produced using hot extrusion method
Go out the magnesium alloy solder wire of various diameters.However, being found in many experiments and production practices：Can be easy to using hot extrusion method
Produce magnesium alloy solder wire of the diameter in more than 2.0mm, when gage of wire is in below 2.0mm, extruding force is multiplied, magnesium
The difficulty increase of alloy welding wire extrusion molding, production efficiency is relatively low.Additionally, by hot extrusion method produce diameter 2.0mm with
Under magnesium alloy solder wire it is partially soft, its welding wire intensity and warpage are mismatched, it is impossible to ensure good linearity, so as to have impact on welding
During wire feed continuity.
In order to reduce diameter in the production difficulty of below 2.0mm welding wires, improve production efficiency and ensure that welding wire is good
The continuity of wire feed in linearity and welding process, becomes the problem that magnesium alloy solder wire is primarily solved.
Current Domestic production magnesium alloy solder wire exist subject matter be：
(1) fracture of wire problem, because alloying component deviation, hydrogen content and impurity content is higher and machined parameters problem caused by weldering
The easy fracture of wire of termination process, therefore the chemical composition of welding wire should be controlled, improve smelting technology, pay close attention to the quality control on the surface of welding wire；
(2) serious suction hydrogen, hot tearing and the strength of joint that welding process occurs in the presence of the welding parameter because of mistake be not high,
During wire feed because wire feed is discontinuous caused by welding wire insufficient strength and surface defect, even fracture of wire the problems such as, therefore improve weld seam
Formability, Development of Novel welding method, brightness welding wire be improve welding wire welding process Main way.
The content of the invention
In order to solve the above-mentioned technical problem, the present invention provides a kind of preparation method of magnesium alloy solder wire, and the method is by molten
Two main techniques of refining and extruding obtain the welding wire of 1~2mm of diameter, and the welding wire fracture of wire phenomenon is few, and weld strength is high.
Therefore, technical scheme is as follows：
A kind of preparation method of magnesium alloy solder wire, comprises the following steps：

2) pure magnesium ingot is melted in iron crucible, adds 5# flux, stay in 5~7min after pure magnesium ingot is completely melt, 10
~12min and 15~17min add the mixture of magnalium intermediate alloy and magnesium zinc intermediate alloy in three times；It is sprinkled into 5# flux protections
Melt, obtains magnesium alloy fused mass；Stirring, using being skimmed after argon gas degasification；
3) crystallizer ingot casting is used on semicontinuous casting machine after cooling, standing, obtains the magnesium of a diameter of 200~300mm
Alloy cast ingot；
4) use 2500T extruders by the magnesium alloy ingot pre-extrusion of a diameter of 200~300mm for diameter 25~
65mm ingot castings；
5) it is the welding wire of a diameter of 1~2mm by the ingot casting extruding of a diameter of 25~65mm to use 400T extruders.
Further, step 4) condition that carries out pre-extrusion using 2500T extruders is：The magnesium alloy ingot temperature is
390~440 DEG C, extrusion speed is 1~3m/min, and lubricant is done using graphite.
Further, step 5) condition that carries out secondary extrusion using 400T extruders is：The temperature of the magnesium alloy ingot
It it is 390~440 DEG C, 3~6m/min of extrusion speed does lubricant using graphite.
Further, aluminum content is 25%~35% in the magnalium intermediate alloy.
Further, it is 6~14% that zinc is contained in the magnesium zinc intermediate alloy.
Further, the mass ratio of magnalium intermediate alloy and magnesium zinc intermediate alloy is 3~9 in the mixture：1.
Further, step 3) in used on semicontinuous casting machine the technique of crystallizer ingot casting for：Magnesium alloy fused mass is drawn
Enter to be placed in the shunting disk of crystallizer inner sleeve core, enter the inner metal sleeve of crystallizer after being shunted by shunting disk and dummy ingot constitutes
In space, while opening protection compression ring for molten metal provides gas shield；680 DEG C~710 DEG C of pouring temperature, drawing ingot speed degree 30~
60mm/min, 0.01~0.08Mpa of cooling water pressure, secondary cooling coolant-temperature gage are 40~50 DEG C.
It is to add intermediate alloy in three times in D.C.casting technique relative to the innovative point of prior art, secondly
It is secondary extrusion magnesium alloy solder wire technique, causes that last welding wire product grains degree is uniform, welding performance is good.
Because the average grain size of the magnesium alloy ingot of a diameter of 200~300mm obtained in early stage is less than or equal to 100
μm；Obtained welding wire can not only weld magnesium alloy plate of the same race (AZ31 or AZ61), it is also possible to weld the magnesium alloy of heterogeneity
Plate (AZ31 and AZ61), can also weld the magnesium alloy plate (die casting state AZ31 and As-extruded AZ31) of different conditions；Welding process
Middle droplet transfer stabilization, appearance of weld is good；The tensile strength of welding point improves at least compared with traditional magnesium alloy solder wire
16%.
