Description
Technical field
It is an object of the present invention to provide a kind of three layers of anti-bacteria stainless steel/aluminium/stainless steel composite material and its manufacture method, belong to
Composite manufacturing field.
Background technology
Aluminum products kitchenware thermal conductivity factor is big, nimble light and handy, cheap, but decay resistance is poorer than stainless steel products, and
Be inconvenient to clean, if long as cookware materials usage time, adverse effect can be produced to human body；Stainless steel products beautiful outline form
See, easy cleaning, it is harmless, but its thermal conductivity factor is small, waste the energy and expensive；The current cooker in China such as pressure
Pot, common frying pan are substantially made using fine aluminium, aluminium alloy, the pig iron, stainless steel homogenous material, wherein stainless steel products development ten
Divide rapid, the trend of substituted aluminium and Al-alloy products.But stainless steel products than it is great, heat conductivility is poor, price is higher；To make
Temperature becomes uniform in stainless-steel pan, can use the method for soldering or Pressure Welding in the compound lastblock aluminium sheet of stainless steel bottom, such process
More, production cost is high；It is and such as right with the improvement of people's living standards, have higher requirement to the hygiene of cooker
The material being in contact with food needs certain performance such as anti-Escherichia coli, staphylococcus aureus；If exploitation is a kind of existing
High heat transfer passes magnetic material, has anti-microbial property material again, will bring great market value.
The content of the invention
The present invention's will provide a kind of three layers of anti-bacteria stainless steel/aluminium/stainless steel composite material and its manufacture method, can overcome
The poor thermal conductivity of anti-bacteria stainless steel, price and than it is great with aluminium corrosion resistance and harmfulness the shortcomings of.
The present invention, which is achieved in that, is characterized in that procedure of processing is：
1. base raw material selects：Austenite antimicrobial stainless steel is selected on upper strata, and core material selects fine aluminium, and lower floor selects ferrite not
Become rusty steel；
2. base：By step（1）The core material and upper and lower layer material chosen are surface-treated using mechanical means, make oxidation
The impurity such as skin, passivation layer remove；Then treat composite surface using wire brush or wire drawing machine finely to be polished, increase the thick of surface
Rugosity is beneficial to follow-up compound；Finally degreased using alcohol washes surface, foul etc., drying；Following symmetrical three are carried out afterwards
Prepared by layer composite plate blanks, core material puts centre, and its outer stack is striden suddenly（1）The upper and lower chosen, levels and sandwich layer
Surface to be composite is fitted, and surrounding spot welding is fixed, composite plate blanks；
3. rolling：By step（2）Obtained vacuum composite plate base is sent into protective atmosphere heating furnace, carries out conventional heating, heating
Temperature is 400 DEG C~430 DEG C, is sent into mill milling afterwards, and accumulation rolling reduction ratio is more than 30%, is then cold-rolled to nearly product rule
Lattice；
4. annealing：By step（3）Composite is made, 350 ~ 400 DEG C are annealed.
Advantage of the present invention and good effect：
There is good antibiotic property, the lightweight of sandwich layer pure aluminum material and good heat conduction by upper strata austenite antimicrobial stainless steel
Property, and the magnetic conductivity that lower floor's ferritic stainless steel is good, improve heat-transfer effect and solve the problems, such as pan discoloration, make three layers to resist
Bacterium stainless steel/aluminium/stainless steel composite material has light weight, intensity height, good heat conductivity, corrosion resistance are good, and anti-microbial property is good etc.
Advantage.
Brief description of the drawings
Fig. 1 composite plate schematic cross-sections；
1 in figure --- upper strata, 2 --- sandwich layer, 3 --- lower floor.
Specific implementation：
Example now is combined into produce the thick three layers of anti-bacteria stainless steel/aluminium/stainless steel doubles of 3mm, as shown in Figure 1.The production process of the present invention
For：Base raw material selection → base → rolling → annealing.
Procedure of processing is：
1. base raw material selects：Upper strata preferred dimension is 2000mm x 1000mm x 3mm30480 austenite antimicrobial stainless steels,
Core material preferred dimension is 22000mm x 1000mm x 2mm 1050 fine aluminiums, and lower floor's preferred dimension is 22000mm x
1000mm x 3mm 430 ferritic stainless steels；
2. base：By step（1）The core material and upper and lower layer material chosen are surface-treated using mechanical means, make oxidation
The impurity such as skin, passivation layer remove；Then treat composite surface using wire brush or wire drawing machine finely to be polished, increase the thick of surface
Rugosity is beneficial to follow-up compound；Finally degreased using alcohol washes surface, foul etc., drying；Following symmetrical three are carried out afterwards
Prepared by layer composite plate blanks, core material puts centre, and its outer stack is striden suddenly（1）The upper and lower chosen, levels and sandwich layer
Surface to be composite is fitted, and surrounding spot welding is fixed, composite plate blanks；
3. rolling：By step（2）Obtained vacuum composite plate base is sent into protective atmosphere heating furnace, carries out conventional heating, heating
Temperature is 400 DEG C~430 DEG C, is sent into mill milling afterwards, rolling with (stock) tension, accumulation rolling reduction ratio 50%, is then cold-rolled near
Product specification 3mm；
4. annealing：By step（3）Composite is made, 400 DEG C are annealed, annealing time 1 hour.
