Abstract
The present invention relates to a compound method for copper and stainless steel, particularly to a compound method for copper and stainless steel which are exclusively used for processing kitchen cookers and are compounded by copper T2 and stainless steel 304. The method comprises the following processing steps: a, respectively intercepting a copper circular piece and a stainless steel circular piece according to the specification of a cooker to be manufactured; b, cleaning the surfaces of the copper circular piece and the stainless steel circular piece; c, coating brazing flux and sprinkling brazing material on two correspondingly and mutually compound surfaces of the copper circular piece and the stainless steel circular piece; d, putting the copper circular piece and the stainless steel circular piece on a brazing machine to be heated and formed after the copper circular piece and the stainless steel circular piece are superposed; obtaining a copper and stainless steel compound plate after cooling. The present invention has the advantages of simple and cheap investment devices, few technologic steps, high processing efficiency and material saving.
Description
Technical field
Disclosed by the invention is a kind of copper and stainless complex method, more particularly be a kind of be exclusively used in processing kitchen cooker by copper T2 and stainless steel 304 both mutually compound copper and stainless complex methods.
Background technology
Owing to having, the kitchen cooker of making of copper T2 and the mutually compound copper that constitutes of stainless steel 304 sheet materials-stainless steel clad plate such as pot, basin, bowl etc. conduct heat soon, are heated evenly, are difficult for sticky, good heat insulating, advantage such as attractive in appearance in addition, durable in addition, thus comparatively in one's favour.Though China is with above-mentioned manufacture of materials kitchen cooker or claim that the producer of vessel is more, their employed copper-stainless steel clad plates all are to lean on external import.This composite plate of import is both to be rolled by hot rolling technology by large-scale equipment of hot rolling to be integrated, and cuts off into massive plate then.Use hot rolling technology production, the equipment input amount is big, and just Given this complex process and require highly, causes copper T2 with import to compare generally with common pure stainless steel ware with the price of the cooker of stainless steel 304 composite plates production and will exceed about 5～6 times.And if wanting an autonomous investment complete set to be used to produces the equipment of above-mentioned composite plate, total cost is about nearly hundred million yuans, and non-China ordinary enterprises can bear; And the waste of raw materials that is caused as pot base, basin base, bowl base etc. that intercepts corresponding small dimension from the massive plate loading and unloading of import is comparatively serious, because the composite plate that complete equipment of hot rolling can't rolling small dimension.
The Chinese patent publication number is that CN1362299A discloses a kind of " stainless ladle box belongs to the manufacturing process of core material ", it is " carries out pickling after stainless steel substrates and metal-cored tablet are put into buck and embathed; clear water rinsing again; behind the airing stainless steel substrates and metal-cored tablet surface electrostatic are planted the sand rough polish; metal-cored tablet is formed overlapping layers in the middle of two-layer stainless steel substrates, after the butt-joint flanging, send the heating furnace heating; put into the roller press roll forming after coming out of the stove, carry out annealing in process at last." to make the existing deficiency of composite plate with this scheme be processing step and to relate to equipment still more, causes long processing time, efficient low, processing cost is higher.As: after superimposed, need in regular turn through butt-joint, heating, roll extrusion, annealing the stainless steel substrates of rough surface processing, metal-cored tablet.
Again, Chinese patent publication number CN1425557A has introduced a kind of " aluminium and stainless steel clad metal plate and manufacturing process thereof ", because of the manufacturing process of this technical scheme is identical with aforesaid CN1362299A, therefore exists aforesaid weak point equally.
Also, Chinese patent Granted publication CN1058145C has introduced " manufacturing of double metallic composite material cooking vessel ", though this technical scheme has the few advantage of processing step, but because it is to adopt explosive that two kinds of metallic plate blasts are compound, not only explosive is difficult to buy, and the also very difficult assurance of safety problem, therefore also be unwell to the manufacturer that produces cooker in enormous quantities.
Summary of the invention
The object of the present invention is to provide a kind of with equipment cheapness and less investment, technology is simple, working (machining) efficiency is high, little copper and the stainless complex method of spillage of material when being put to use.
For achieving the above object, the technical scheme of copper provided by the invention and stainless complex method comprises following procedure of processing:
A. intercept copper, stainless steel disk respectively according to the cooker specification that will make;
B. copper coin sheet and stainless steel disk are carried out the cleaning surfaces processing;
C. on two of copper coin sheet and stainless steel disk mutually compound corresponding surfaces the coated brazing flux, spill solder;
D. be placed on hot briquetting on the high frequency brazing machine with copper coin sheet and stainless steel disk are superimposed, promptly obtain copper and stainless steel clad plate after the cooling.
Brazing flux of the present invention, solder are silver-bearing copper (CuAg) brazing flux, solder.
Heating-up temperature of the present invention is 500 ℃～800 ℃.
The advantage that the inventive method has the used device simple and inexpensive, processing step is few, working (machining) efficiency is high, save material.
Description of drawings
Figure 1 shows that the one piece of copper coin being intercepted according to the cooker specification that will make and the shape figure of one piece of corrosion resistant plate.
Structure chart after Figure 2 shows that copper coin that the inventive method obtains and corrosion resistant plate being mutually compound.
The specific embodiment
Embodiment 1:
According to the specification of the cooker of required making such as pot or basin or bowl, calculating copper coin sheet 1 and the material that the material of answering blanking is copper T2 is the size of the stainless steel disk 2 of stainless steel 304; Pickling degreasing is carried out on surface to copper coin sheet 1 and stainless steel disk 2, to obtain cleaning pretreatment; Surface to copper coin sheet 1 and stainless steel disk 2 is spread the silver-bearing copper brazing flux, is spilt ag-cu solder (CuAg); Copper coin sheet 1 and stainless steel disk 2 be superimposed with each other to be put into be heated to 550 ℃ of moulding on the high frequency brazing machine.Promptly obtain copper and stainless steel clad plate 3 after the cooling by be directly used in processing kitchen utensil shown in Figure 2 such as pot or basin or bowl.
Embodiment 2:
Only change heating-up temperature and pressure into 650 ℃ respectively, all the other are with embodiment 1.
Embodiment 3:
Only change heating-up temperature and pressure into 750 ℃ respectively, all the other are with embodiment 1.
Claims (3)
