Abstract
The present invention provides composite multiplayer metal plate and its producing process. The present invention features that polished metal core material layer is inserted between polished stainless steel sheet and copper sheet, and the they are heated and rolled into composite multiplayer metal plate for manufacturing kitchen ware and other product. The technological process is simple and efficient and the composite plate kitchen ware has no demerits of stainless steel kitchen ware.
Description
Affiliated technical field
The present invention relates to the metallic plate Materials And Manufacturing Processes, particularly the multilayer composite metal plate Materials And Manufacturing Processes.
Background technology
Stainless steel products of the prior art, particularly cookware article, its shortcoming are that the efficiency of heating surface is low, and it is inhomogeneous to be heated.Through the stainless steel cooker of improvement, be to be coated with the antiseized glue of last layer in the bottom of a pan, improved the shortcoming that the inequality of being heated is easy to the burnt end, but its pre-treating technology complexity, cost up, and durability is not enough.Other has at the bottom of the compound pot, promptly adds a slice stainless steel after adding one deck aluminium flake at the bottom of the stainless steel again on aluminium flake, though performance makes moderate progress, can not avoid the bottom of a pan and lower periphery to have burnt crust to occur all the time, and processing technology is also very complicated, and cost is higher.
Summary of the invention
Purpose of the present invention is intended to overcome the deficiencies in the prior art and provides a kind of technology simple, and easy to operate, cost is low, the multilayer composite metal plate Materials And Manufacturing Processes that energy consumption is low.
The object of the present invention is achieved like this:
A kind of multilayer composite metal plate Materials And Manufacturing Processes, this technology is stainless steel substrates and sheet metal to be put into 60～80 ℃ 10～20% buck embathed 1～2 minute, through putting into 8～15% hydrofluoric acid pickling after the clear water rinsing again after 0.5～1 minute, clear water rinsing once more, behind the airing, the surface of stainless steel substrates and sheet metal is after the equidirectional polishing of electrostatic sand-planting coarse sandpaper (roughness Ra=5～8 μ), metal film stack is added stratification, the two-layer of ragged edge is stainless steel substrates and copper sheet, after the one end butt-joint flanging, level pushes away the heating furnace of putting into 200～500 ℃ and heated 15～20 minutes, put into the roller press roll forming of 2000KN～3000KN after coming out of the stove immediately, 200～250 ℃ of annealing heat treatments 1～1.5 hour, the cooling back was put down and is composition metal plate again.
---described sheet metal is meant corrosion resistant plate, aluminium sheet, copper coin, iron plate, stainless iron plate or alloy sheets.
---described superimposed layer can be that the monolithic stainless steel substrates is two-layer for being three stratotypes of sheet metal, four stratotypes, five stratotypes, six stratotypes and seven stratotypes in the middle of stainless steel substrates and the copper sheet with double deck type, the ragged edge of unitary piece of metal copper sheet.
The composition metal plate that produces with this technology has good deep drawn, the bond strength height, and heat conduction is even and efficient is high, exquisite appearance, durable.What the present invention was used is the standard roll unit, small investment, and energy consumption is low, and instant effect has overcome the shortcoming of stainless steel cooker in the past, is subjected to client's favorable comment deeply.
Description of drawings
Fig. 1 is the covering sectional drawing (Fig. 1-1 is three stratotypes, and Fig. 1-2 is five stratotypes) after the present invention's one end butt-joint flanging.
Fig. 2 is the structure section figure (Fig. 2-1 is three stratotypes, and Fig. 2-2 is five stratotypes) after the roll forming of the present invention.
Fig. 3 is a process chart of the present invention.
Among the figure: 1 is stainless steel substrates, and 5 and 3 is copper sheet, and 2,3,4 is described sheet metal.
The specific embodiment
With three layers of example: during enforcement, get the corrosion resistant plate of 0.1～3mm, 0.1～3mm core material metal aluminum sheet and 0.1～0.3mm copper coin, 15% the buck of putting into 70 ℃ embathed after 1.5 minutes with the hydrofluoric acid pickling half a minute of putting into 10% after the clear water rinsing again, clear water rinsing again, behind the airing, with equidirectional polishing three sheet metals of 46# static coarse sandpaper to roughness Ra=7 μ, aluminium flake is put in the middle of stainless steel substrates and the copper sheet, after the one end butt-joint flanging, level pushes away the box electrothermal furnace of putting into 400 ℃ and heated 18 minutes, promptly put into the roller press roll forming of 2400KN after coming out of the stove, 220 ℃ of annealing heat treatments 70 minutes, use the composition metal plate more flat than flat-bed machine after the cooling again, the standby material of opening manufactures a finished product.
