An effective solution to the problems in the related art has not been proposed yet.
Disclosure of Invention
Aiming at the problems in the related art, the invention provides a production method of a flexible aluminum alloy photovoltaic conductor, which aims to overcome the technical problems in the prior related art.
Therefore, the invention adopts the following specific technical scheme:
the flexible aluminum alloy photovoltaic conductor is prepared from the following raw materials in parts by mass:
50-92 parts of aluminum, 20-25 parts of copper, 15-20 parts of iron, 5-10 parts of silicon, 3-5 parts of magnesium, 2-3 parts of zinc, 1-3 parts of boron, 1-2 parts of manganese, 1-2 parts of nickel, 1-2 parts of zirconium, 1-2 parts of rare metal and unavoidable impurities.
Further, the rare metals include one or more of scandium, rhenium, rubidium, yttrium, tungsten, vanadium, and cerium.
Further, the preparation method is used for preparing the flexible aluminum alloy photovoltaic conductor and comprises the following steps:
weighing all raw materials required by the aluminum alloy photovoltaic conductor material according to the mass parts;
cleaning a smelting furnace, heating to 700-750 ℃, taking an industrial aluminum ingot, and putting the industrial aluminum ingot into the smelting furnace to completely melt the aluminum ingot to obtain aluminum liquid;
adding copper, iron, silicon, magnesium, zinc, boron, manganese, nickel, zirconium and rare metals into the molten aluminum, heating in a stepped manner at 800-845-920-1650 ℃, stirring and mixing uniformly after all raw materials are melted, and keeping the constant temperature at 1650 ℃;
introducing high-pressure nitrogen and inert gas into the smelting furnace for refining, then slagging off, and filtering the mixed molten metal to obtain a clean aluminum alloy melt after slagging off is finished;
keeping the aluminum alloy melt at constant temperature, then pouring to form an aluminum alloy casting strip and cooling to 450 ℃;
rolling the aluminum alloy cast strip by a rolling mill to obtain an aluminum alloy linear conductor with a designed size through primary rolling;
sequentially carrying out primary drawing, secondary drawing and tertiary drawing on the aluminum alloy linear conductor to form an aluminum alloy filament with a composite design size;
and twisting the drawn aluminum alloy filaments, selecting and matching a pressing die according to different specifications, and controlling proper tension during twisting to form the flexible aluminum alloy photovoltaic conductor.
Furthermore, in the third step, the time for raising the temperature in the smelting furnace from 800 ℃ to 845 ℃ is ten minutes, the time for raising the temperature from 845 ℃ to 920 ℃ is fifteen minutes, and the time for raising the temperature from 920 ℃ to 1650 ℃ is 25 minutes.
Further, the nitrogen is added in the fourth step for thirty minutes, then a refining agent is added for refining, and the air is exhausted and the slag is removed after twenty minutes of refining.
Further, when the aluminum alloy mixed liquid is stirred in the third step, the stirring should be carried out stably, too large waves should not be excited, so that an oxide film is prevented from being involved in the melt, the stirring is carried out for 2 to 3 hours, meanwhile, the temperature in the smelting furnace is controlled at 820 ℃, the stirring quality is ensured, and the aluminum alloy liquid is fully mixed.
Further, in the seventh step, the primary drawing speed is 10-30m/s, the secondary drawing speed is 8-10m/s, and the tertiary drawing speed is 5-8m/s.
Further, in the fifth step, the aluminum alloy cast strip is subjected to surface milling treatment, wherein the surface milling temperature is 480-500 ℃ for hot rolling, then the aluminum alloy cast strip is subjected to cold rolling until the temperature of an outlet material is 280 ℃, and then the aluminum alloy cast strip is subjected to annealing treatment for 1-3 hours at the temperature of 330-360 ℃.
The invention adopts the following raw material medicines:
copper: copper is the earliest metal used by humans. In early prehistoric times, people began to mine open-air copper ores and use the obtained copper to manufacture weapons, utensils and other utensils, and the use of copper has a profound effect on the progress of early human civilization. Copper is a metal present in the earth's crust and in the ocean. The copper content in the earth crust is about 0.01%, and in individual copper deposits, the copper content can reach 3% to 5%. Copper in nature is mostly present as a compound, i.e., a copper mineral. The copper ore and other minerals are polymerized into copper ore, and the mined copper ore is subjected to mineral separation to form copper concentrate with high copper-containing grade. Is the only metal which can be produced in large quantities naturally, is also present in various ores and can be used in the elemental metallic state and in the form of brass, bronze and other alloys in industry, engineering and processes.
Iron: ferrous metal is one of the most widely distributed metals on earth. About 5.1% of the crust mass, and the fourth place in the distribution sequence of the elements, second only to oxygen, silicon and aluminum. Iron is a lustrous silvery white metal, hard and ductile, has a melting point of 1535 ℃, a boiling point of 3000 ℃, strong ferromagnetism, and good plasticity and thermal conductivity. The specific heat capacity is about 0.46 x 1000J/KG x DEG C, and the iron metal is taken from iron ore. Limestone, coke and iron ore are put into a blast furnace layer by layer, high-temperature airflow is blown from the bottom to make the coke glow red, and then iron is reduced from oxides, melted into liquid and flows out from the bottom of the furnace.
Magnesium: magnesium is a light, ductile, silvery white metal. Is the eighth most abundant element in earth's crust and also the ninth most element in universe. Density 1.74 g/cm 3 Melting point 648.8 ℃. Boiling point 1107 ℃. Valence +2, ionization energy 7.646 ev, is one of the light metals, ductile, reacts with hot water to release hydrogen, and burns to produce dazzling white light, and many metals are prepared by thermal reduction of their salts and oxides. Magnesium metal can be combined with most non-metals and almost all acids, most bases, and organic chemicals including hydrocarbons, aldehydes, alcohols, phenols, amines, fats and most oils, with magnesium only slightly or not at all.
The invention has the beneficial effects that: by controlling the heating temperature, the annealing temperature, the cold-hot rolling process and the material components, the strength, the electric conductivity, the heat resistance, the flexural fatigue resistance, the corrosion resistance and the creep resistance of the aluminum alloy conductor are improved, the processing quality is ensured, the problems of easy creep deformation, easy fracture, low connection reliability and the like of the conventional aluminum alloy conductor are solved, and the aluminum alloy conductor material with different flexibilities can be manufactured according to the twisting quantity of the aluminum alloy filaments.
