It is removed, so as to improve the operation of the unit of solute concentration in solvent.Evaporator is widely used in chemical industry, food industry, system
The industry such as medicine.
Contain substantial amounts of salts substances, corrosion product and various microorganisms in evaporator recirculated cooling water, due to not to it
Water process is carried out, evaporator operation a period of time Hou Shui side can have substantial amounts of calcium carbonate and magnesium carbonate dirt and algae, microorganism are become silted up
Mud, foundry loam etc., these dirts are firmly attached to copper pipe inner surface, cause heat transfer deterioration, circulating pressure to rise, unit vacuum drop
It is low, the operational efficiency of unit is influenceed, causes larger economic loss.Inwall is influenceed by medium and welding stress, and is easily oozed
Liquid leakage and corrosion phenomenon are leaked, causes functions of the equipments to decline, if processing is not in time, can not only cause equipment scrapping, or even causes weight
Big production accident.Therefore, evaporator inner wall necessarily requires round and smooth, its cooperate or connection member weld seam should it is tight, firmly,
Must not there are seepage, delamination, corrosion phenomena.
The content of the invention
In order to solve the above problems, the present invention provides a kind of new casting mode and the aluminium alloy produced using this method
Foil, final foil have good mouldability, weldability, a corrosion resistance, and tissue and performance are uniform, and metallurgical imperfection is few, respectively to
The opposite sex is small, is highly suitable as evaporator inner wall.
Evaporator inner wall aluminium alloy foil material continuous cast-rolling method of the present invention, comprises the following steps：
The first step, gets out required raw material first, and the waste material in raw material uses fine aluminium, total input amount≤35% of waste material, its
Middle secondary waste input amount≤30%, virgin aluminium ingot >=65%, and raw material is loaded in smelting furnace and melted；
Second step, material composition is stirred, skims and adjusts to the raw material after fusing；
3rd step, the raw material after skimming is subjected to refining treatment in smelting furnace；
4th step, the raw material after refining treatment is transferred in Wen Baolu again and carries out double refining and stewing process；
5th step, the raw material after double refining is handled are discharged into degasification tank progress degasification and take off Slag treatment；
6th step, the raw material after Slag treatment will be taken off and carry out filter cleaner with the binary channels twin-stage ceramic filter plate of Rose Box；
7th step, then the raw material after filter cleaner is discharged and is transported in casting and rolling machine and carries out casting, will continuously it be arranged by milling train
The raw material gone out is rolled into the thick aluminum alloy coiled materials of 7mm by casting；
8th step, the aluminum alloy coiled materials after casting are carried out to first time cold rolling again into aluminum alloy coiled materials thick 5mm；
9th step, the aluminum alloy coiled materials after first time cold rolling are subjected to first time homogenizing annealing processing；
Tenth step, the aluminum alloy coiled materials after the processing of first time homogenizing annealing are carried out to the cold rolling of three to four times, respectively closed aluminium
Gold is rolled into the thick aluminum alloy coiled materials of 2.5mm, 1.5mm, 1.0mm, 0.65mm, then carries out trimming processing；
11st step, the aluminum alloy coiled materials after trimming is handled carry out cold rolling twice again, respectively by aluminum alloy rolling be made 0.43mm,
Aluminum alloy coiled materials thick 0.3mm, then carry out making annealing treatment for second；
12nd step, the aluminum alloy coiled materials after second is made annealing treatment carry out paper tinsel and rolled, aluminum alloy rolling is made respectively again
0.22mm, 0.15mm thick evaporator inner wall foil.
Production process of the present invention is simple, can improve production efficiency, and the final foil produced has good mouldability, weldering
Connecing property, corrosion resistance, tissue and performance are uniform, and metallurgical imperfection is few, and anisotropy is small, is highly suitable as evaporator inner wall.
