The method overcomes the defaults of the air-annealing and vacuum annealing, qualifies the aluminium foil with thin oxide film after annealing, good degreasing, short annealing time, and can be used for large-scale production.
Description
Affiliated technical field
The present invention relates to a kind of method for quenching high voltage electronic aluminum foil finished products, belong to rolling, the manufacture field of metal finished product paper tinsel.
Background technology
The heterogeneous microstructure of high voltage electronic aluminum foil directly has influence on the various performances after its corrosion, and the finished products of high voltage electronic aluminum foil is the committed step of its heterogeneous microstructure of control.By finished products, can improve it and { 100} plane texture occupation rate, adjust its grain-size, improve the surface quality of paper tinsel, finally improve the specific volume after the high voltage electronic aluminum foil corrosion.At present, mainly adopt air annealing and vacuum annealing.The high voltage electronic aluminum foil surface film oxide was thicker after air annealed weak point was to anneal, alkali cleaning difficulty when causing corrosion, and residual oxide film is also inhomogeneous after the alkali cleaning, the place that residual clouds oxide film is many is difficult to corrosion, the place that residual oxide film is few is easy to corrosion, so under the certain situation of etching time, can reduce corrosive effect, specific volume is descended.The weak point of vacuum annealing is to avoid the two large problems in air annealing, but annealing time is oversize, is difficult to large-scale industrial production.
Summary of the invention
The present invention is directed to that above-mentioned problems of the prior art provide a kind of and overcome the deficiency of above method for annealing, annealed method for quenching high voltage electronic aluminum foil finished products in protective gas.
The technical solution adopted for the present invention to solve the technical problems is: (1) charges into insured retreat furnace with protective gas, makes the interior oxygen level of stove be lower than 0.08%; (2) furnace temperature rises to 250-320 ℃, is incubated 4-15 hours, and heat-up rate is controlled at 1-12 ℃/minutes; (3) furnace temperature rises to 500-550 ℃, is incubated 4-15 hours, and heat-up rate is controlled at 1-12 ℃/minutes; (4) machine that blows in is chilled to furnace temperature soon and comes out of the stove for 60-120 ℃.
Described protective gas is helium or other rare gas elementes.The preferred value of above-mentioned parameter is: (1) charges into insured retreat furnace with protective gas, makes the interior oxygen level of stove be lower than 0.05%; (2) furnace temperature rises to 280-300 ℃, is incubated 5-10 hours, and heat-up rate is controlled at 5-10 ℃/minutes; (3) furnace temperature rises to 520-540 ℃, is incubated 5-10 hours, and heat-up rate is controlled at 5-10 ℃/minutes; (4) machine that blows in is chilled to furnace temperature soon and comes out of the stove for 80-100 ℃.
The invention has the beneficial effects as follows that annealing back aluminium foil surface oxide film approaches, deoils effective; Annealing time is short, can large-scale industrialization production.
