Abstract
The present invention provides composite aluminium-stainless steel plate and its producing process. The present invention features that polished aluminium plate and stainelss steel sheet are heated and rolled into composite 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 stainelss steel kitchen ware.
Description
Affiliated technical field
The present invention relates to metallic plate Materials And Manufacturing Processes, particularly aluminium and stainless steel clad metal sheet material and manufacturing process thereof.
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 aluminium that energy consumption is low and stainless steel clad metal sheet material and manufacturing process thereof.
The object of the present invention is achieved like this:
A kind of aluminium and stainless steel clad metal sheet material and manufacturing process thereof, this technology is stainless steel substrates and metal aluminium flake 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 metal aluminium flake is after the equidirectional polishing of electrostatic sand-planting coarse sandpaper (roughness Ra=5～8 μ), after the end butt-joint flanging with two metal sheets, 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 aluminium and stainless steel clad metal sheet material again.
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 to live the shortcoming of stainless steel cooker, is subjected to client's favorable comment deeply.
Description of drawings
Fig. 1 is the section of structure of composition metal plate of the present invention, and 1 is stainless steel substrates among the figure, and 2 is aluminium flake;
Fig. 2 is a process chart of the present invention.
The specific embodiment
During enforcement, get corrosion resistant plate and the 0.1～3mm metal aluminum sheet of 0.1～3mm, 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, polish to roughness Ra=7 μ with 46# static coarse sandpaper is equidirectional, after the end butt-joint flanging with aluminium flake and stainless steel substrates, 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, using flat than flat-bed machine after the cooling was aluminium and stainless steel clad metal sheet material again, and the standby material of opening manufactures a finished product.
Claims (2)
1. an aluminium and stainless steel clad metal sheet material and manufacturing process thereof, it is characterized in that stainless steel substrates and metal aluminium flake are put into 60～80 ℃ 10～20% buck to be 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 metal aluminium flake is after the equidirectional polishing of electrostatic sand-planting coarse sandpaper (roughness Ra=5～8 μ), after the end butt-joint flanging with two metal sheets, 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 aluminium and stainless steel clad metal sheet material again.
2. according to the described metallic plate Materials And Manufacturing Processes of claim 1, it is characterized in that the composition metal plate of making according to the described feature of claim 1.
