Text D

Although nowadays we may produce cast iron by melting it with electricity, cupola is the most widely used furnace for this purpose.

The first cupola in Russia was built by Batashev in 1774. Because of its simple construction and high productivity cupola began to be widely used in foundry. There are some thousands of cupolas in all foundries of the USSR.

The construction of cupolas is steadily (постоянно) developed. Both cupolas of old those of modern construction are used at present in foundries. Some of them are fully automated and meet the necessary requirements (удовлетворять требованиям).

The cupolas may produce from some kilograms to 20-30 tons of cast iron per hour. The biggest cupola in the world, built in 1972, in the USA, can produce 100 tons of cast iron per hour.
