Would you like to see how aluminum is made? Are you interested in observing the process of turning clay into metal with the help of electricity? Then welcome to the RUSAL factory.
Three factories of RUSAL are located in Sayanogorsk while the largest factory in the world engaged in aluminum production is situated in Krasnogorsk.
This is the aluminum factory of Sayanogorsk. Aluminum is the third most abundant element (after oxygen and silicon), and the most abundant metal, in the Earth's crust. It has the symbol Al, and its atomic number is 13. There is a lot of aluminum in nature but the one we deal with is obtained industrially and is not met in nuggets as gold.
Alum is produced at the electrolysis center using baths with baked anodes. The anodes are placed into a bath with electrolysis, covered with clay and are then turned into metal.
This is a baked anode. The modern technology helps to get rid of harmful substances at the stage of production.
Lines of electrolysis cells are stretching beyond the horizon. These new workshops were built in 2004-2006 and united in a separate factory later on. The production process is almost totally automatized.
With the help of the construction on the crane aluminum is taken out of electrolysis baths and poured into buckets that will be carried to the foundry. 2 tones of clay, 0,5 tones of carbon for the anode and 15000 kW an hour are needed to obtain one ton of alum.
Then a bucket with aluminum is put on a truck and taken to the foundry. A necessary alloy is made of regular aluminum in a special furnace.
Pure aluminum is poured into a furnace.
Metal is pouring into small ingots.
Aluminum is a beautiful metal.
There were times when alum was considered more expensive than precious metals. In 1855 when the metal was first introduced to the public, it was called 'silver made of clay'. Napoleon III, Emperor of France, is reputed to have given a banquet where the most honored guests were given aluminum utensils, while others used regular golden dishes.
Metal is poured into vertical cans.
Here long cylinders are cut in parts.
Russia became the first country in the world engaged in alum industrial production. Initial kilograms of Soviet aluminum was obtained with the help of electrolytic tanks.
After the fall of the USSR the aluminum industry saw tough times being influenced by Trans World Group that deprived factories of funds necessary for production development and local criminals who hoped to get fast profit. In 1994 first steps were made directed at acquisition of independence. In 2007 United company Russian Aluminum was created. It has become the largest manufacturer of aluminum and clay in the world.
