We do not have aluminium spoons or forks in the kitchen anymore, however theкe is something made of aluminium there which we use pretty often. It is foil.
Aluminium foil is one of the most popular materials used in food production, electrical industry, pharmacological industry, and automobile industry. It has great heat conduction characteristics, it is hygienic, easy to use and, what is most important, it is environmentally sound because it utterly disappears in the ground.
To produce aluminium foil, it is necessary to build a factory with melting furnaces and a rolling mill which could roll out aluminium bars into sheets which are just 5 micrometers thick.
In 1993 such a factory was build near the aluminium production factory in Sayanogorsk we have mentioned in one of our previous articles. Now this factory produces up to 70% of aluminium foil of the country.
It is a melting department. Here they pour melted aluminium into a furnace where it gets degassed. They add modifiers to make the aluminium structure better.
So, the melt is ready. After that they make an aluminium tape (6-10 milimeters thick and 1200-1650 milimeters wide) out of it.
The hot aluminium tape is twisted into rolls...
