Abstract
A technology for manufacturing a steel-aluminum pot with composite bottom includes such steps as providing composite steel-aluminum plate, forming a steel-aluminum pot with an inner layer made of steel, preparing a laminated plate from aluminum plate and magnetic metal plate, attaching it to the aluminum plate of pot bottom by dot welding, heating it to high temp, and high-temp and -pressure pressure welding by a high-power friction press.
Description
Technical field
The present invention relates to a kind of kitchen utensils, particularly a kind of composite-bottom steel-aluminum pot.
Background technology
Aluminum pot is owing to its light weight, and it is good to conduct heat, and obtains to be extensive use of.But aluminium pot also has its defective, the one, and quality is hard inadequately, and wearing and tearing scrape striped easily, and oxide-film is in case damaged, and aluminium matter is easily dissolved in the food of being contained, and the aluminium intake is many can to cause dementia; The 2nd, can not be directly used in electromagnetic oven; The 3rd, when the bottom of a pan thickness was not enough, the high temperature heating can be out of shape, and lip-deep oxide-film can be destroyed.In addition, the pot inner surface can be more coarse as there not being non-sticking lining, adheres to food, non-easy cleaning in the gastronomical process.For this reason, continually develop out all kinds of improved aluminum pot products.Application number 200420022056.9 " a kind of aluminum pressure cooker " discloses a kind of aluminum pot at the compound one deck magnetic conductive metal sheet in pressure cooker bottom, has only solved the problem that is suitable for using on electromagnetic stove.And at aluminum pot inner-wall spraying non-sticking lining, claim according to nearest external test report, adopt certain multinational fluorine-containing non cohesive gel, long-term use can be separated out carcinogenic tetrafluoroethene, therefore, no matter adopting on the inwall aluminium matter or non-sticking lining that its defective is all arranged with pot that food directly contacts.
Summary of the invention
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part, and providing a kind of manufacturing to have the compound end, base thickness is greater than the pot wall thickness, and is compound firm, conduct heat evenly, be suitable on electromagnetic oven, using, and can avoid direct steel-aluminum pot that contacts with aluminium of pot interior food and products thereof.
Purpose of the present invention can reach by following measure:
A kind of method of making composite-bottom steel-aluminum pot, comprise the preparation of steel-aluminum pot, that is with steel-aluminum metal composite plate, make the steel-aluminum pot that contains pot body and the bottom of a pan through machined, the one side of this steel-aluminum pot inwall is a steel disc, and the one side of outer surface of pot bottom is an aluminium flake, it is characterized in that, this method also comprises:
1. prepare at the compound end: aluminium sheet that will be suitable with the bottom of a pan area of plane and magnetic conductive metal sheet are superimposed together after cleaning, and fixedly become the compound end through spot welding;
2. connect: the above-mentioned compound end, is superimposed with the bottom of a pan of steel-aluminum pot again, make the one side of aluminium sheet at the compound end, contact with the aluminium flake in the bottom of a pan, make the bottom of a pan of steel-aluminum pot by spot welding, link into an integrated entity with the compound end that is formed by stacking by aluminium sheet-magnetic conductive metal sheet;
3. heating:, place on the heater and heat with the above-mentioned steel-aluminum pot that fuses and the compound end;
4. pressure welding: the steel-aluminum pot and the compound end that above-mentioned point is welded into one and has heated, place while hot on 1000 tons～1600 tons the friction press and carry out pressure welding;
Thus, making its bottom of a pan contains from top to bottom and to be steel disc-aluminium flake-four layers of compound composite-bottom steel-aluminum pot of aluminium sheet-magnetic conductive metal sheet.
The above-mentioned heating steel-aluminum pot and the temperature at the compound end are at 480 ℃～520 ℃.
The aluminium plate thickness at the above-mentioned compound end is at 2mm～6mm; Described magnetic conductive metal sheet is a kind of corrosion resistant plate, and its thickness is at 0.5mm～0.8mm.
On the aluminium lamination surface of above-mentioned steel-aluminum pot, the oxide-film that has one deck to form through anodized.
Method of the present invention and products thereof has following advantage:
1. improved security to carrying food.Steel-aluminum pot of the present invention, its inwall is steel disc rather than aluminium, has avoided food to contact with the direct of aluminum metal.As everyone knows, take in the aluminium of excess, have to cause dull-witted effect, when food contains acidity, be easy to and aluminium generation combination reaction especially, generate aluminum soluble salt, influenced security food.This pot while also avoids adopting its security so far still not have the non-sticking lining of the fluoropolymer of final conclusion.
2. compound firm.Because the especially pressure welding of high pressure of high temperature, combining between at the compound end and the compound end and the pot body is very firm, can satisfy the safety in utilization of 400 ℃ of dry combustion methods and check.Because outermost layer is a magnetic conductive metal sheet, applicable to electromagnetic oven, and on electric furnace and the common kitchen range.
3. conduct heat evenly, heat effective.The bottom of a pan thickness of product of the present invention is greater than the pot wall thickness, removes to have increased base thickness, be suitable for the high temperature heating, conduct heat good outside, also can under the constant situation of pot body thickness, adapt to user's requirement, the bottom of a pan of accomplishing different-thickness.The magnetic conductive metal sheet of the bottom, thickness preferably 0.5～0.8mm than close limit, improved cost performance of product.
4. pot body outer surface has improved case hardness through anodized, anti-collision, scratches.
