The composite bottom aluminum pot has the advantages of firm composite pot body bottom, little cooking fume, long service life, reasonable production process, excellent performance of the product, suitability for popularization and application on composite pots of the same type.
Description
Technical field
The invention belongs to kitchen utensils technical field, relate to a kind of composite bottom aluminum pot and produce technique.
Background technology
Composite bottom boiler in the market, great majority have layer of metal sheet (as stainless iron plate) again at its bottom of a pan outermost layer, its weak point is: the one, due to the reason of technique or technology, between bottom of pot body and compound sheet metal, the multiple end, is insecure, cause the situations such as aliquation, delamination to occur, affect the service life of product; The 2nd, the heat conduction of individual layer composite bottom aluminum pot is inhomogeneous, can not control kettle temperature below the smoke point of various edible oils, makes the oil smoke that produces when dish-cooking large, affect operating personnel's eyesight and respiratory health, meanwhile, by the wall in kitchen and article sooting, affect attractive in appearance.
Summary of the invention
The object of this invention is to provide a kind of composite bottom aluminum pot that the multiple end is firm, heat conduction is even, cooking fume is little of composite bottom boiler and produce technique.
The object of the present invention is achieved like this:
And producing a technique, the pan bottom structure that it is characterized in that composite bottom aluminum pot is that the bottom outer surface in the bottom of a pan is disposed with binder course, aluminium flake and metal compound bottom sheet downwards by the bottom of a pan.
Above-mentioned metal compound bottom sheet is stainless steel substrates or stainless iron plate.
Above-mentioned aluminium flake thickness is 2～8mm, and the thickness of metal compound bottom sheet is 0.4～0.8mm.
Above-mentioned binder course is the metal material that contains aluminium or iron, and its thickness is 0.3～2mm.
A generation technique, its production stage is:
(1) surface coarsening: sandblast alligatoring is carried out in pot body outer surface bottom, make the outer surface roughness of bottom of pot body reach 5～50 μ m;
(2) coating: plating aluminium on the pot body outer surface bottom after alligatoring, forms described binder course;
(3) composite metal: aluminium flake and metal compound bottom sheet, be shaped to the composite metal of one through HTHP;
(4) compound pot body: the composite metal of step (3) moulding is placed in to the preheating of carrying out together on the binder course that step (2) forms before compound, then is combined in conjunction with composite bottom aluminum pot firmly through high pressure;
The production stage of described composite bottom aluminum pot can be also:
(1) surface coarsening: sandblast alligatoring is carried out in pot body outer surface bottom, make the outer surface roughness of bottom of pot body reach 5～50 μ m;
(2) coating: plating aluminium on the pot body outer surface bottom after alligatoring, forms described binder course;
(3) compound pot body: aluminium flake, metal compound bottom sheet are overlayed successively to the preheating of carrying out together on the binder course that step (2) forms before compound, then be combined in conjunction with composite bottom aluminum pot firmly through high pressure.
Above-mentioned preheat temperature is 400～640 ℃, and described high pressure is 10～2500T.
Above-mentioned coating is thermal spraying.
The present invention has following beneficial effect:
1, the multiple end of pot body, is firm: the aluminum pot that the present invention makes can be smoothly by being first heated to 400 ℃ of then quenchings in room temperature water, 25 above-mentioned loop tests not the fastness of the multiple end at the de-end test (test requirements document of foreign standard to stainless steel composite bottom boiler), between bottom of pot body and composite metal, in conjunction with firmly, solved the unstable technical barrier of double-bottom aluminum pan;
2, cooking fume is little: the metal at the multiple end of pot body is comprised of multilayered metal film, and heat conduction is even, can control preferably temperature of boiler below the smoke point of various edible oils, has solved the large difficult problem of cooking fume.
3, long service life: because the multiple end of pot body of the present invention is firm, not aliquation, not delamination, has solved the problem that pot body damages, reduce service life that other composite bottom boiler causes due to aliquation, delamination.
4, production technology of the present utility model rationally, the function admirable of product, suitablely on multiple layer pot of the same type, apply.
Accompanying drawing explanation
Fig. 1 is structure cross-sectional schematic of the present invention;
Fig. 2 is the enlarged drawing of the A portion of Fig. 1.
The specific embodiment
With specific embodiment, the present invention is described further below:
A generation technique, its production stage is:
1, surface coarsening:
(1) adjust the frock size on the automatic dry type sand-blasting machine rotating disk of four stations, by the pot after stretched, trimming, cleaning, body 1 is bottom-up is placed in frock;
(2) adjusting sandblast air pressure is 6～8kgf/cm
270～80 ° of (0.6～0.8MPa), sandblast distance 100～150mm, angle of gun, carry out alligatoring with 36 object emergies, controls the sandblast time, makes surface roughness reach 10～20 μ m.
2, thermal spraying:
(1) adopt electric arc spraying equipment, the aluminium alloy of two diameter 1.6～2.0mm or ni-al alloyed wire are packed in spray gun, spray pressure is adjusted to 0.4～0.6MPa;
(2) spraying operating voltage is controlled to 30～40V, wire feed voltage 15～20V, regulates spray gun apart from pot body 1 alligatoring position, bottom 200mm left and right, control spray time at 8～10 seconds, can spray and make the binder course 2 that 0.3mm is thick.
3, composite metal:
(1) using the thick aluminium flake 3 of 5mm and thick 430 stainless steel substrates of 0.5mm as metal compound bottom sheet 4 as requested synchronous point be welded into a sheet metal, then be combined into composite metal through HTHP;
4, compound pot body:
(1) the good aluminum pot of thermal spraying is sent into tunnel heating furnace together with above-mentioned composite metal and carry out compound front preheating, if when aluminum pot material is cast aluminium, control furnace temperature between 400～480 ℃; When aluminum pot material is stretching aluminium, control furnace temperature between 560～620 ℃.
(2) with the forcing press of 500～2500T, aluminum pot and composite metal are pressed together, can make composite bottom aluminum pot firmly of the multiple end.
According to actual demand, the thickness of above-mentioned binder course, aluminium flake and stainless steel substrates can be selected respectively in the scope of 0.3～2mm, 2～8mm, 0.4～0.8mm, and surface roughness can be selected within the scope of 5～50 μ m.
The pan bottom structure of the composite bottom aluminum pot going out by above-mentioned generation explained hereafter is that the bottom outer surface in the bottom of a pan is disposed with binder course 2, aluminium flake 3 and metal compound bottom sheet 4 downwards by the bottom of a pan 1, and metal compound bottom sheet 4 is stainless steel substrates or stainless iron plate.
The present embodiment is substantially the same manner as Example 1, its difference is: on the bottom of a pan 1 after coating binder course 2, place successively aluminium flake 3, metal compound bottom sheet 4, carry out together more compound front preheating, finally with the forcing press of 500～2500T, aluminum pot, aluminium flake 3 and metal compound bottom sheet 4 are pressed together, can make composite bottom aluminum pot firmly of the multiple end.
The above, be only preferred embodiment of the present invention, not technical scheme of the present invention done to any pro forma restriction.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all fall within the scope of protection of the present invention.
