Abstract
The present invention provides a method for manufacturing a pot bottom made of a composite metal plate with an anti-oxidation layer. The present invention is characterized in that a stainless steel plate is stamped to form a pot shape; after one surface of a copper plate which has the same shape and size with the stainless steel plate is ground and roughened, anti-oxidation layers are electroplated on both of the two surfaces of the copper plate, and then an aluminum plate with the same shape and size is arranged between a stainless steel pot bottom after being roughened and the copper plate of which the inner surface is roughened and electroplated to be heated and impacted to form a pot bottom made of a composite steel plate with an anti-oxygen layer. The method of the present invention is simple and feasible, and the product manufactured by the method has high thermal efficiency without scorching the bottom. The composite metal plate of the pot bottom has the advantages of firm combination and high durability, and the present invention is an advanced method for producing high-performance pots.
Description
Technical field
The present invention relates to a kind of preparation method of the bottom of a pan, particularly have the preparation method in the clad metal sheet the bottom of a pan of anti oxidation layer.
Background technology
Mostly the bottom of a pan of pot in the prior art is to be made by the metallic plate of individual layer such as cast iron plate, corrosion resistant plate, aluminium sheet, copper coin etc.Their shortcoming is that fast heat is cold soon, and it is inhomogeneous to be heated, easily derivation crispy rice or burnt bottom and the lower periphery of sticking with paste.Long heating though improved the function of being heated, is unable to undergo in the bottom of a pan that existing clad metal sheet is made, and clad metal sheet is easy to split, should be powerful and lose.
Summary of the invention
Purpose of the present invention is intended to overcome the deficiencies in the prior art and a kind of efficiency of heating surface height is provided, and is heated evenly, and the clad metal sheet that is difficult for the burnt paste and the bottom of a pan is in conjunction with firm, long-lived preparation method with clad metal sheet the bottom of a pan of anti oxidation layer.
The object of the present invention is achieved like this:
A kind of preparation method with clad metal sheet the bottom of a pan of anti oxidation layer, it is characterized in that earlier corrosion resistant plate being struck out a pot type, with the outer surface of pot bottom alligatoring of polishing, in addition with after the equirotal copper coin one surface finish alligatoring of shape, anti oxidation layer is all electroplated on copper coin two surfaces, again the equirotal aluminium sheet of shape is placed through at the bottom of the stainless-steel pan of alligatoring and electroplate through alligatoring between the copper coin of inner surface, be heated to impact after 500 ℃ and be pressed into the clad metal sheet the bottom of a pan with anti oxidation layer.
---the anti oxidation layer on the described copper coin electroplating surface can be nickel coating, chromium coating or plating molybdenum layer.
---the anti oxidation layer of the outer surface that described copper coin is electroplated without alligatoring can polish off easily and spill copper coin.
Description of drawings
Fig. 1 is the structural representation of products made thereby of the present invention;
Fig. 2 is the open circumferential crimping schematic diagram of products made thereby of the present invention;
Fig. 3 is the local cross-sectional schematic of amplifying in the bottom of a pan of products made thereby of the present invention.
In Fig. 1～Fig. 3,1 is copper coin for aluminium sheet, 6,8 is respectively plating at the anti oxidation layer, 7 of copper coin surfaces externally and internally for rusty gold steel plate, 5 for hingle, 4 for a pot body, the 2 pot mouthful peripheries for self crimping, 3.
The specific embodiment
Strike out a pot body by the different requirements of thick book with corrosion resistant plate, matsurface is worn at the external end of pot, in addition the thick copper coin of 0.2～2.0mm is caused and size that the pot body is complementary, compound one side is ground be placed in the electroplating pool after coarse, make copper coin two surfaces all plate the oxidation resistant metal level of one deck.Guarantee that copper coin can not produce oxide layer in the time of 500 ℃ when compound heating.Then aluminium sheet is placed between pot body and the copper coin, the three is heated to be placed on after 500 ℃ to strike out on the forcing press has pot at the bottom of the fabulous complex copper of heat conductivility.
Method simple and feasible of the present invention, product thermal efficiency height, the non-burnt end,, the bottom of a pan clad metal sheet is in conjunction with firmly, and is durable in use, is the advanced method of producing high-effect pot
Claims (3)
1, a kind of preparation method with clad metal sheet the bottom of a pan of anti oxidation layer, it is characterized in that earlier corrosion resistant plate being struck out a pot type, with the outer surface of pot bottom alligatoring of polishing, in addition with after the equirotal copper coin one surface finish alligatoring of shape, anti oxidation layer is all electroplated on copper coin two surfaces, again the equirotal aluminium sheet of shape is placed through at the bottom of the stainless-steel pan of alligatoring and electroplate through alligatoring between the copper coin of inner surface, be heated to impact after 500 ℃ and be pressed into the clad metal sheet the bottom of a pan with anti oxidation layer.
2, the preparation method with clad metal sheet the bottom of a pan of anti oxidation layer according to claim 1 is characterized in that the anti oxidation layer on the copper coin electroplating surface, can be nickel coating, chromium coating or plating molybdenum layer.
