The purpose of the embodiment of body, it is not intended that in the limitation present invention.
Fig. 1 is the flow chart for the clad metal sheet preparation method that one embodiment of the invention provides.The clad metal sheet system
Preparation Method may include following steps：
Step S11 is clean by the stainless steel plate and the aluminium alloy plate surface clean.
Wherein, it is to remove by the stainless steel plate purpose clean with the aluminium alloy plate surface clean in the step S11
The impurity such as greasy dirt, the dust on stainless steel plate and the aluminium alloy plate surface are removed, it is miscellaneous to ensure not introducing in follow-up course of hot rolling
Matter and the effect for keeping hot rolling.
Wherein, it is specially to the surface clean process of the stainless steel plate：Stainless steel plate is put into metal cleaner, passed through
Ultrasonic degreasing purified treatment, dried after being rinsed with clear water.
For example, stainless steel plate can be put into metal cleaner, it is 60~80 DEG C to control temperature, and it is net to carry out ultrasonic degreasing
Change 10~20min of processing, with cold water flush, be finally putting into 3~10min of drying in 100~240 DEG C of drying ovens.
Surface clean process to the aluminium alloy plate is specially：By the aluminium alloy plate through alkaline solution treatment, and with cold
Hot water injection, then through salpeter solution immersion treatment, finally with being dried after cold water flush.
1~8min, temperature are soaked for example, the aluminium alloy plate can be placed in the NaOH solution that concentration is 15~30wt%
Then control successively uses cold water, hot water injection at 30~70 DEG C, place into 15~30wt% HNO3In solution immersion 2~
10min, with cold water flush, it is finally putting into 3~10min of drying in 100~240 DEG C of drying ovens.
Step S12, respectively by the face wire drawing to be combined of the stainless steel plate and the aluminium alloy plate.
Wherein, respectively by the stainless steel plate and the mesh of the face wire drawing to be combined of the aluminium alloy plate in the step S12
Be the increase stainless steel plate and aluminium alloy plate face to be combined roughness, to increase institute in follow-up bonding processes
The adhesion between stainless steel plate and the aluminium alloy plate is stated, so as to improve the recombination rate of stainless steel plate and aluminium alloy plate.
Step S13, the face to be combined of the stainless steel plate and the aluminium alloy plate is activated respectively.
In the present embodiment, the step S13 is specifically included：
The face to be combined of the stainless steel plate and the aluminium alloy plate is activated respectively by chemical mode.
In the step S13 respectively by the face to be combined of the stainless steel plate and the aluminium alloy plate activate purpose be for
Follow-up method hot rolling is prepared.
Step S14, the stainless steel plate is laminated into stacking with the aluminium alloy plate by the way that respective face to be combined is corresponding
Plate, and plywood progress hot rolling is pressed to form composite plate.
The step S14 specifically may include：The stainless steel plate and the aluminium alloy plate are passed through into respective face to be combined
It is corresponding to be laminated into plywood, and composite rolling is carried out again after the plywood is heated so that the stainless steel plate and the aluminium
Alloy sheets are combined with each other to form composite plate in the crystallization aspect of respective faying face.
For example, made of after can the stainless steel plate be laminated with the aluminium alloy plate by the way that respective face to be combined is corresponding
Plywood is sent into continuous-type furnace and heated, and heating-up temperature is 250~500 DEG C, and the heat time is 10~20min, has been heated
Composite rolling is carried out into rear be sent into the milling train of preheated roll.Wherein, the preheating temperature of the roll crown of milling train is 200~300
DEG C, while roll crown needs to use lubricant to lubricate.
Step S15, the composite plate is made annealing treatment.
The step S15 specifically may include：Stainless steel plate after rolling and aluminium alloy plate are sent into annealing furnace, start to rise
Temperature, heating rate are 33~66 DEG C/min, rise to after 250~350 DEG C and keep 0.5~3h of constant temperature.150 DEG C are subsequently cooled to,
Simultaneously natural cooling is taken out, forms hot rolled plate.
Wherein, in the step S15 by the purpose that the composite plate is made annealing treatment be so that the stainless steel plate and
The aluminium alloy plate is more uniform in the crystallizing layer of faying face, while eliminates due to internal stress caused by Rolling compund, with more
Optimize the properties of product after hot rolling well.
Wherein, the annealing in the step S15 can eliminate the soldering stress of stainless steel and both aluminium alloys, promote
Spread between the two material atom, intensified metallurgy bond strength.Because in heat treatment process, due to heat activated effect, position
Wrong and atom can migrate.With the rise of temperature, aluminium alloy occurs to reply successively and partial, re-crystallization, reply make in matrix
Internal stress and internal strain reduce, be beneficial to the plasticity of base material, but the intensity of base material remains at higher level.
The heat treatment temperature of hot rolling and annealing in the present invention can both make the intensity enhancing of alloy, and and can makes conjunction
Internal stress inside gold effectively discharges, so as to improve the exfoliation corrosion resistance of alloy.
The clad metal sheet preparation method that first embodiment of the invention provides is described stainless by hot rolling mode
Steel plate and the aluminium alloy plate are combined together in respective crystallization aspect, described multiple to obtain the clad metal sheet of the present invention
The requirement of electronic equipment case material high to intensity, in light weight can both have been met by closing metallic plate, can make gorgeous outside drawing again
Case and reduction processing cost.
In addition, the clad metal sheet adhesion obtained using the clad metal sheet preparation method of the present invention is good, rear
It is indeformable, wrinkle resistant, not stratified in the process such as continuous punching press.
