History

After the abolition of serfdom in 1861, industry began to develop rapidly in Russia — new enterprises emerged, joint-stock companies were formed, and investment increased. Following the construction of the Moscow–Kursk and Ryazhsk–Vyazma railways, Tula became an important railway transit hub. The question arose of supplying the industrial centre of Russia with pig iron and of building an iron smelting plant in Tula.

1886: Construction began on the Sudakovsky (now Kosogorsky) metallurgical plant.
1897: The first pig iron was tapped from the first blast furnace. By the end of the year, 1.5 million poods of foundry pig iron had been smelted.
1898: The second blast furnace was put into operation.
1899: Peak pig iron production. The plant smelted 91 thousand tonnes.
1905: The plant was mothballed due to the economic downturn in the country.
1912: The "Joint-Stock Company of Tula Iron Foundries" was founded.
1913: Reconstruction of the plant began.
1914: The second blast furnace was commissioned. Total pig iron output reached 80 thousand tonnes per year.
1915: A cement shop was built to utilise blast furnace slag, and a shell shop was built to fulfil military orders.
1917: In connection with the revolutionary events in the country, blast furnace No. 1 was shut down.
1918: Blast furnace No. 2, the power station and cement production were shut down. The plant was nationalised.
1926: The Tula Provincial Executive Committee gave the plant the name "Kosogorsky Metallurgical Plant named after F.E. Dzerzhinsky".
1930: The government issued a decision on the development of KMZ. Construction of blast furnace No. 3 began in December.
1932: The 100th and 10th most powerful blast furnace in the USSR — Kosogorsky blast furnace No. 3 with a volume of 697 cubic metres — was blown in. The capacity of the blast furnace shop increased fourfold, and pig iron output rose to 159 thousand tonnes.
1941: German occupation. KMZ was evacuated to the Ural city of Lysva.
1942: Restoration of the enterprise began. All three blast furnaces were gradually brought back on line.
1945: Pig iron output exceeded pre-war levels by a factor of 2.5.
