Description
Technical field
The utility model relates to a kind of cooker pot field, and particularly a kind of pot bottom has the pot of steel aluminium infiltration fused layer.
Background technology
As everyone knows, the pot of metal is as the main tool of heated food, and the thermal conducting function of aluminum pot is far longer than the steel pot, but aluminium cooker body intensity is limited, and the method for the inapplicable electrical induction of generally using now, so everybody hankers after designing at the bottom of the various aluminum steel compound pot very much.For example Chinese patent CN201227154Y relates to be a kind of aluminum pot compound pot at the bottom of, be compositely fixed with permeability magnetic material on the bottom of a pan of aluminum pot, it is characterized in that: the bottom of a pan of described aluminum pot is provided with convex tendon, and convex tendon is with zoning territory, the bottom of a pan, and permeability magnetic material is fixed in each zone by the high-temperature metal spraying.Owing to be compositely fixed with permeability magnetic material on the bottom of a pan, it can be implemented in electromagnetic stove and use.The disadvantage of this structure is that permeability magnetic material is a convex tendon, is not the structure of full wafer, therefore exists to be subjected to the long-pending little and dispersion of magnetic surface, causes the problem of heating efficiency difference.
Disclosed a kind of method of making composite-bottom steel-aluminum pot of Chinese patent CN101028668A and products thereof and for example.Earlier make steel-aluminum pot by steel-aluminum composite plate, inwall simultaneously is a steel disc; Superimposed superimposed with the aluminium flake in the bottom of a pan again with aluminium-magnetic conductive metal sheet, spot welding links into an integrated entity, and the high temperature heating is placed on the pressure welding of carrying out HTHP on the large-tonnage friction press, obtain steel-aluminium-four layers of compound composite-bottom steel-aluminum pot of aluminium-magnetic conductive metal, its base thickness is greater than the pot wall thickness.Be characterized in the complex welding synthermal heating in back with various metals, carry out the high temperature pressure welding again, this patent has solved the little problem of heating surface area, but because aluminium is different with the thermal expansion factor of steel, may cause each layer metal not fuse effectively after the compacting cooling, influence the problem of compound pot body firmness.
Also have Chinese patent CN101352305A utility model to relate to a kind of aluminium alloy compression casting pan with compound bottom.It comprises aluminium alloy compression casting pan pot body, stainless iron compound bottom sheet, is characterized in the direct and smooth compound one that is of bottom of pot body of stainless iron compound bottom sheet.The utility model also relates to the combination process of above-mentioned aluminium alloy compression casting pan with compound bottom.This combination process is to make aluminium alloy compression casting pan with compound bottom through steps such as die casting, cleaning surfaces, coating complexing agent, paster, precompressed, compound, pressurize cooling, surperficial subsequent treatment.This technology is more reasonable, and it is to pass through induction coil in compound process, and aluminium is heated to 450-630 ℃, and the duration is 40-45s, makes aluminium combine with the stainless iron compound bottom sheet, and such process time is oversize, is unfavorable for producing in enormous quantities; Because each part pot body all is independent heating, so the energy resource consumption height, is unfavorable for environmental protection, and the equipment complexity; The melt temperature of aluminium is 660 ℃ as you know, and therefore heat influences aluminum ions diffusion velocity to 450-630 ℃ of aluminum ions active deficiency, and the firmness of product is not high enough.
Summary of the invention
The utility model will solve the not high problem of traditional handicraft steel aluminium multiplicity, and a kind of aluminum steel compound pot is provided, and its steel aluminium composite surface steel aluminium ion can fully fuse, and firmness is stronger.
The technical scheme that its technical problem that solves the utility model adopts is: the aluminum steel compound pot that a kind of aluminium matter the bottom of a pan is provided: comprise pot body, the steel the bottom of a pan sheet of aluminium matter, it is characterized in that: the pot body of described aluminium matter and the contact-making surface of steel the bottom of a pan sheet have steel aluminium infiltration fused layers.Aluminium matter pot body is heated to 400～500 ℃, and steel the bottom of a pan sheet is heated to 780-820 ℃, with both rolling combinations on friction press or hydraulic press, and cooling naturally after the rolling end.780-820 ℃ steel the bottom of a pan sheet contacts under forcing press with the surface of 400～500 ℃ aluminium matter pot body, because the two has the temperature difference of 300-400 ℃ of degree, and the heat conductivility of aluminium is fine, be raised to more than the melting temperature of 660 ℃ of degree and 800 ℃ rapid combination of active steel ion in the aluminum ions temperature of contact-making surface so at once, formed the steel aluminium infiltration alloy film of contact-making surface; Because steel the bottom of a pan sheet thinner thickness, thermal capacity is limited, adds the perfect heat-dissipating of aluminium, and the aluminium surface surpasses 660 ℃ high temperature, just form in the part, and the time of effect is very short, therefore can not exert an influence to aluminium matter pot body; The cooling naturally of rolling end back because the temperature height of steel can reduce pot cooling velocity of body aluminum component, reduces contraction distortion; Through at the bottom of the steel aluminium compound pot of this processing technology moulding, its firmness is higher, because process velocity is fast, is more suitable for producing in enormous quantities.
For stretched aluminium matter pot body, described heating-up temperature is 450-500 ℃.Because aluminium matter pot body is stretched, its rigidity increases, so heating-up temperature selects the upper limit relatively good.
For the aluminium matter pot body through die casting, described heating-up temperature is 400-450 ℃.Because the aluminium matter pot body rigidity of die casting is relatively low, so be limited to good under the heating-up temperature selection.
As preferably, the upper surface of steel the bottom of a pan sheet is shot-peening or frosted.Coarse steel surface more helps aluminum ions infiltration combination.
As preferably, the lower surface of aluminium matter pot body adopts shot-peening or frosted or is processed into annular corrugated or spiral lamination.The aluminium ion of rough surface more helps fusion.
As preferably, steel the bottom of a pan sheet is a basin shape stage body.The compound egative film of steel can be fully around the aluminium matter the bottom of a pan that encases easy deformation in pressing process like this, thereby has guaranteed the shape of rolling back pot body, has improved the rigidity and the intensity of the bottom of a pan appearance.
As preferably, the pot body of aluminium matter is a flat bottom cooker.
As preferably, the pot body of aluminium matter is a digester.
The beneficial effect that the utlity model has is: the bottom of a pan of pot body and the steel of aluminium matter compound firmly and technical process simple, be suitable for production in enormous quantities; Production process energy-saving and emission-reduction, more compliance with environmental protection requirements.
