Performance is connect also to be affected.The weld tabs tissue that composite diffusion method is prepared is thick；What composite algorithm and composite diffusion method were prepared
Golden tinfoil paper material, welding performance is poor；And though the weld tabs brazing property that ultrasound casting hot rolling method is prepared out is preferably, production efficiency
It is low.
The content of the invention
Present invention seek to address that the processing problems of gold-tin alloy, there is provided a kind of to prepare the heat that process gold-tin alloy foil
Rolling method, this method technical process simple economy, weld tabs can uniformly be sheared and good welding performance, be adapted to industrialized production.
The preparation method for processing gold-tin alloy foil of the present invention, for the gold-tin alloy of hard fragility, obtains
The foil that 0.1mm is obtained after the ingot casting of even fine and close and few segregation and large deformation is its crucial step, on this basis again to alloy
Carry out the alloy foil that homogenizing annealing treatment obtains light.
It is of the invention to process gold-tin alloy foil preparation method, comprise the following steps：
A. gold-tin alloy raw material is prepared, Sn content in alloys is 20%, and the raw material of preparation is put into graphite earthenware by balance of gold
The melting at 450 DEG C in the common smelting furnace, the aluminium alloy of fusing is poured into the graphite casting die of preheating in crucible, is taken out after cooling, is obtained
To the ingot casting of 2-8mm.
B. by gold-tin alloy ingot casting in 220 DEG C of homogenizing annealing 1h.By the ingot casting after annealing in 240-150 DEG C of liquid oil
Heating, hot rolling obtains solder alloy foil, and rolling final thickness is 0.1-0.05mm.
C. the greasy dirt of alloy surface is removed.By in vacuum annealing furnace of the alloy foil after cleaning at 240-180 DEG C
Annealing 1h.
Preferred technical scheme is, using the graphite moulding cast of preheating in the step A, to obtain the thick ingot castings of 2-8mm.
Preferred technical scheme is that the step B hot-rolled temperatures change with the thickness change of ingot casting.
Preferred technical scheme is the 1h that annealed in vacuum annealing furnace after the step C gold-tin alloys foil cleaning, and it is moved back
Fiery temperature is 240-180 DEG C.
The present invention can process gold-tin alloy foil hot-rolling method, and hot-rolling method compared to existing technology is with ingot casting
The change of thickness its rolling temperature also changes.Its advantage is：Cast using the graphite of graphite crucible melting and preheating
Mould is poured into a mould, and obtains ingot casting after cooling, and ingot casting is annealed 1h at 220 DEG C, and in 240-150 DEG C of hot rolling.With changing for The ingot casting thickness
Become rolling temperature with changing, finally give the foil of 0.1-0.05mm thickness.The gold-tin alloy paper tinsel that the present invention is prepared
Material can be machined, and welding performance is good, good fluidity, and brazing temperature response is fast.Present invention process process is simple, it is easy to
Implement, production efficiency is high and economy, it is adaptable to industrialized production.
