Abstract
An Al-alloy foil with high strength, high plasticity and high corrosion resistance for the heat dissipating fins of air conditioner contains proportionally Al, Fe, Si, Cu, Mn and Ti. Its preparing process includes such steps as proportionally mixing raw materials, smelting, casting, holding the temp at 770-780 deg.C for 3-5 min, hot rolling, colding rolling, straightening, and annealing.
Description
Technical field:
The present invention relates to alloy foil and manufacture method thereof that a kind of high strength, high-ductility, corrosion resistant air conditioner radiation fin are used.
Background technology:
Original air conditioner radiation fin adopts hot rolling blank production to have the shortcoming that technical process is long, production cost is high with aluminium foil, also because alloy purity height, the mechanical property increase rate is little, the reviewing phenomenon takes place in fin often, and thickness is more than 0.1mm, if reduced thickness simultaneously, the intensity of the finished product aluminium foil under the equal state, plasticity descend, therefore, with the air-conditioning paper tinsel of hot rolling blank production the cost of every conditioner is raise, energy consumption is big.
Summary of the invention:
The purpose of this invention is to provide a kind of blank and produce alloy foil and the manufacture method thereof that thickness is used less than high strength, high-ductility, the corrosion resistant air conditioner radiation fin of 0.1mm.The parts by weight of each chemical ingredients are in the alloy foil that air conditioner radiation fin of the present invention is used: Al:99.3, Fe:0.20～0.30, Si:0.05～0.15, Cu:0.05, Mn:0.12～0.20, Ti:0.02～0.05, it is according to following operation manufacturing: a, according to parts by weight is Al:100, Fe:0.20～0.30, Si:0.05～0.15, Cu:0.05, Mn:0.12～0.20, the ratio of Ti:0.02～0.05 is fused into liquid metal after above-mentioned chemical ingredients is mixed, be to pour into a mould under 685～690 ℃ the condition in aluminium water teeming temperature, under 770～780 ℃ condition static 3～5 minutes then is that 950～1000mm/min casting becomes the thick big volume of 7.0mm with roll casting speed; B, carry out cold rolling with the working modulus more than 95% then; C, align when being cold rolled to 0.6mm; D, after 260～290 ℃ of annealing obtain the alloy foil that air conditioner radiation fin is used.Interior tissue is to avoid occurring causing that the thick MnAl6 of crystal grain distributes mutually among the present invention, liquid metal is finished at short notice solidified by two Kun formula continuous casting and rolling methods and once become base with two parts of hot rolling, dendrite interval and metallic compound are tiny, the degree of super saturation of solute element in sosoloid improves, and intensity raising, the recrystallization temperature of cast-rolling stock are improved; By method and other off-set facility of control working modulus, roll speed, guarantee the visual appearance of product; The finished products temperature under the final state determined by to the aluminium foil interior tissue guarantees the high strength of product, the performance requriements of high-ductility.The invention has the advantages that:
1, realized breakthrough with cast-rolling stock production high-quality, the aluminium foil of thickness below 0.1mm, casting and roll process has not only shortened Production Flow Chart, simplified production process, a large amount of facility investments and energy consumption have been saved, and casting and the compactness that has improved metal structure that combines of rolling, eliminated defectives such as shrinkage cavity, loose, segregation, saved crop, back-end crop operation, lumber recovery improves;
2, the adding of Mn element increases alloy strength, the aluminium foil that the aluminium foil intensity that cast-rolling stock is produced is produced apparently higher than hot rolling blank; The adding of Mn element has stoped recrystallization process, improved the temperature of recrystallize, simultaneously the MnAl6 dispersoid particle is to the recrystal grain inhibition of having grown up, energy is the refinement recrystal grain significantly, make finished product thickness have good plasticity like this less than the aluminium foil of 0.1mm, do not ftracture during deep-draw, the air-conditioning paper tinsel is being satisfied the high-intensity while, plasticity, deep drawability are good; The adding of Mn element makes the corrosion resistance of air-conditioning paper tinsel suitable with former air-conditioning paper tinsel; In fine aluminium system, improve the content of alloying element Mn, not only guaranteed the corrosion resistance that product is final, and improved final intensity index, the deep drawability of product, improved technological standards accurately.
