Abstract
A technology for manufacturing stainless steel wrapped aluminium sheet includes such steps as blanking stainless steel sheets and aluminium sheets, hemming said stainless steel sheets, boiling stainelss steel sheets and aluminium sheets in alkali solution, rinsing in clean water, pickling, rinsing in clean water, putting one aluminium sheet between two stainless steel ones, collision welding, heating, rolling pressing, heat treating, and flatening. Its advantages include simple technology, low cost, and low energy consumption. Its product can be used to make kitchen appliance with high heat conductivity.
Description
The present invention relates to the covering technology of metal material, specifically a kind of manufacturing process of stainless steel wrapped aluminium sheet.
Stainless steel is very extensive in the kitchen tools sector application, but it has a shortcoming, is exactly that thermal conductivity is very poor, make kitchen tools after, the efficiency of heating surface is very low, heats inhomogeneous.In order to address this problem, just at the bottom of the individual layer stainless-steel pan, glue the good aluminium flake of one deck thermal conductivity with chemical method, this cries the multiple end, and the product of making is multiple bottom stainless steel kitchen tools.Because of multiple bottom stainless steel kitchen tools still exist the efficiency of heating surface very low, heat uneven defective, the gesture that has become superseded, be exactly to add one deck aluminium flake in the stainless steel kitchenware bottom on aluminium flake, to add one deck stainless steel substrates more in addition, be that stainless steel wrapped aluminium sheet is made the composite bottom stainless steel kitchen tools, can improve its being heated evenly property greatly.But the processing technology of this stainless steel wrapped aluminium sheet is for opening material, the aluminium flake jet-bedding, and chemicals is handled in earlier stage, and pickling is cleaned, sanding, butt-joint, heating in medium frequency is suppressed, spot welding, operations such as Pressure Welding, complex process; Cost of investment is big, only suppresses an operation and just need join the above friction press of kiloton, could satisfy and suppress operation; Energy consumption is big, and heating in medium frequency machine single head per hour needs 250KW, and the heating in medium frequency machine is general minimum to be four statures.
The manufacturing process that the purpose of this invention is to provide a kind of stainless steel wrapped aluminium sheet, this technology is simple, and cost is low, and energy consumption is low.
Purpose of the present invention can realize by following scheme: it comprises following sequential steps:
(a) open material: stainless steel substrates, aluminium flake are opened material;
(b) flanging: stainless steel substrates is converted into
Shape becomes two stainless steel substrates integrators
Shape, the thickness of its opening size and aluminium flake is complementary;
(c) clean: stainless steel substrates and aluminium flake are put into buck and are boiled and wash, and boil and carry out the clear water rinsing after washing, and carry out the clear water rinsing again after then putting into the hydrofluoric acid pickling;
(d) stack: cleaned stainless steel sheet, aluminium flake are superposeed, add a slice aluminium flake in the middle of two stainless steel substrates;
(e) butt-joint: after stainless steel substrates and aluminium flake superposeed, synthesizing
The contact position of two stainless steel substrates of shape is carried out butt-joint and is become the stainless steel aluminium flake;
(f) heating: the stainless steel aluminium flake after the butt-joint heats;
(g) roll extrusion: the stainless steel aluminium flake is put into milling train carry out roll extrusion;
(h) heat treatment: the stainless steel aluminium flake is put into heating furnace annealing back cool off with stove;
(i) more flat: as to carry out more flatly after the stainless steel aluminium flake is come out of the stove, be the finished product of stainless steel wrapped aluminium sheet.
The present invention contrasts prior art and has following advantage: 1, because of not needing jet-bedding, sanding, suppressing and Pressure Welding, so technology is fairly simple; 2, because do not suppress operation, just needn't use friction press, what this friction press kiloton was above wants more than 100 ten thousand yuan, and what the present invention used is the standard roll unit, as long as about 500,000 yuan, so cost of investment is low; 3, do not use the heating in medium frequency machine that needs 1000kw with the box type heater of 100kw, so energy consumption is low.
Fig. 1 is a technological process block-diagram of the present invention;
Fig. 2 is the structural representation of product of the present invention;
Fig. 3 is the structural representation of product of the present invention after the stack operation.
To further specify the present invention below.
(a) open material: with stainless steel substrates, aluminium flake on demand size open material;
(b) flanging: stainless steel substrates is converted into
Shape makes two stainless steel substrates synthesize one
Shape, the thickness of its opening size and aluminium flake is complementary;
(c) clean: it is that 15% buck boils and washes that stainless steel substrates and aluminium flake are put into concentration, carry out decontamination, water temperature guarantees between 60 ℃-80 ℃, carry out the clear water rinsing again after boiling 1 to the 2 minute time of washing, put into 10% hydrofluoric acid pickling after the clear water rinsing again, remove the oxide on surface, 1 minute pickling time, carry out the clear water rinsing again:
(d) stack: cleaned stainless steel sheet and aluminium flake are superposeed, synthesizing
The opening part of two stainless steel substrates 01,03 of shape adds a slice aluminium flake 02;
(e) butt-joint: after stainless steel substrates and aluminium flake superposeed, synthesizing
The contact position 04 of two stainless steel substrates 01,03 of shape is carried out butt-joint and is become the stainless steel aluminium flake;
(f) heating: the stainless steel aluminium flake after the butt-joint is put into heating furnace heat, heating and temperature control is between 320 ℃-350 ℃.And the stainless steel aluminium flake is heated evenly, be 15-20 minute heat time heating time;
(g) roll extrusion: the stainless steel aluminium flake after will heating is put into milling train and is carried out roll extrusion;
(h) heat treatment: will put heating furnace into by the stainless steel aluminium flake that the milling train roll extrusion is come out and carry out annealing in process, temperature is controlled between 200 ℃-250 ℃, cools off with stove with 1 to 1.5 hour;
(i) more flat: as to carry out more flatly after the stainless steel aluminium flake is come out of the stove, be the finished product of stainless steel wrapped aluminium sheet.
