Industrial aluminum profile is an indispensable basic raw material in the national economy and is widely used in construction, packaging, transportation, power and other fields. Since the founding of New China for more than 60 anni, from exploration, mining, smelting to processing, China's industry has complete upstream and downstream industries, complete industrial chains, and can give full play to its overall advantages; from technology research and development to engineering design, from engineering construction to production and logistics services, China's industrial aluminum profile industry has complete categories and supporting systems, which can fully guarantee the healthy development of the industrial aluminum profile industry.
A Brief History of Industrial Aluminum Profile Industry Development
The word Aluminium is derived from the ancient Roman language Alumen. In 1746, German scientist Porter made anodized industrial aluminum profiles from alum.
The Englishman David taught the melting and oxidizing of industrial aluminum profiles to obtain metal. Industrial aluminum profiles were unsuccessful. In 1809 David named the envisioned metal Alumium and later changed it to Aluminium. In 1825, Danish scientist Osler used potassium reduction and oxidation of industrial aluminum profiles to obtain a small amount of metal industrial aluminum profiles.
French scientist Deville used sodium to reduce NaALCL4 complex salt and set up a factory to produce some industrial aluminum profiles helmets, tableware and toys, which are expensive and equivalent to gold.
Hall of the United States and Elut of France have also obtained patents for the production of metal industrial aluminum profiles using the cryolite-oxidized industrial aluminum profile molten salt electrolysis method.
Pittsburgh in the United States established the first industrial aluminum profile factory, and industrial aluminum profile production has entered a new stage. The invention of the Bayer method for the production of oxidized industrial aluminum profiles from industrial aluminum profiles, clay and ore, and the progress of DC electrolytic technology have laid the foundation for the development of industrial aluminum profiles to industrial scale.
Late 19th century
The price of industrial aluminum profiles has fallen thousands of times. Firstly, because Siemens improved the generator in the 1870s, it has cheap electricity; secondly, because Heroult in France and CM Hall in the United States respectively developed the dissolution of aluminum oxide profiles in cryolite (Na3AlF6) Electrolytic method. This pioneering move enables industrial aluminum profiles to be produced on a large scale and lays down the industrial method of aluminum profiles in the world's electrolytic industry today. So far, various industrial aluminum profiles have entered millions of households.
Early 20th century
In addition to daily necessities, industrial aluminum profiles are mainly used in the transportation industry. Manufacture car body from industrial aluminum profile plate.
American Industrial Aluminum Profiles supplies industrial aluminum profile parts to Wright Brothers for making small aircraft. Automotive engines have begun to use industrial aluminum alloy castings, and the shipbuilding industry has also begun to use industrial aluminum alloy alloy plates, profili, and castings. With the increase in the production of industrial aluminum profiles and the advancement of science and technology, the application of industrial aluminum profiles in other industrial sectors (such as medical equipment, industrial aluminum profile printing plates, deoxidizers for steelmaking, packaging containers, eccetera.) is also increasing. Extensive, greatly stimulated the development of industrial aluminum profile industry.
German A. Wilm invented the hard industrial aluminum profile alloy (Al-Cu-Mg alloy) in 1906, which doubled the strength of industrial aluminum profiles. It was widely used in aircraft manufacturing and other arms during the First World War. industria. Since then, Al-Mn, Al-Mg, Al-Mg-Si, Al-Cu-Mg, Al-Zn-Mg and other industrial aluminum alloys with different compositions and heat treatment states have been successively developed. These alloys have different characteristics and functions The use of industrial aluminum profiles has been greatly expanded, and the application of industrial aluminum profiles in industrial sectors such as construction, automobili, railways, ships and aircraft manufacturing has been rapidly developed.
The world's industrial aluminum profile output has increased to more than 45,000 tonnellate. Has started large-scale production of industrial aluminum profile foils and other new products, such as industrial aluminum profile hoses, industrial aluminum profile furniture, industrial aluminum profile doors, windows and curtain walls, and industrial aluminum profile cookers and household industrial aluminum profile foils and other new products They have also appeared one after another, making the popularity of industrial aluminum profiles a big step forward.
During the Second World War
The industrial aluminum profile industry achieved rapid growth under the strong stimulation of the military industry. In 1943, the total output of the original industrial aluminum profile soared to 2 million tons. After the war, due to the sharp reduction in military requirements, the total output of the original industrial aluminum profile fell to 1 million tons in 1945. However, as the major industrial aluminum profile companies actively developed new civilian products, the application of industrial aluminum profiles was gradually promoted to instruments , Electronics, transportation, daily hardware, food packaging and other fields, increasing the demand for industrial aluminum profiles year by year.
The world's industrial aluminum production exceeds copper, ranking first in non-ferrous metals.
The world's primary industrial aluminum profile production has exceeded 16 million tons, and the recycled industrial aluminum profile consumption has reached 4.5 million tons. The industrial aluminum profile industry's production scale and production technology level have reached quite high levels.
Late 20th Century Early 21st Century
The concept of "sustainable development" was proposed. The consumption of industrial aluminum profiles in developed countries has decreased, and the countries with rich industrial aluminum profile mineral resources such as Australia, Brazil, India, and Jamaica have increased production of aluminum oxide profiles.
In the long run, the technological innovation direction of industrial aluminum profiles mainly revolves on the following aspects: low carbon, low energy consumption, low pollution, long life and efficient green smelting technology, domestic production and intelligence of key industrial aluminum profile equipment, Recycling and efficient use of intermediate products, auxiliary products and wastes of profile products, industrialization of industrial aluminum profiles, earth and mineral substitutes, and development of high strength and high damage tolerance industrial aluminum alloy materials.
