Mechel Group’s Chelyabinsk Metallurgical Plant has completed the repair of several large units at once: blast furnace No 1, converter No 3 and continuous casting machine No 5. More than 200 million rubles were invested in their repair. The renovation work affected, among other things, environmental equipment.

Converter No 3 is a steelmaking unit with a capacity of over 1.2 million tonnes of steel per year. During the repair, the specialists checked the gas duct sealing, covered the inner surface of the pipe with wear-resistant refractory bricks. This regular maintenance prevents iron oxide from entering the atmosphere.

Also, the mechanisms of the continuous casting machine No 5 in the oxygen-converter shop was updated, which annually produces more than 800 thousand tons of steel billets. We repaired the vacuum apparatus - a device that removes harmful impurities during metal melting and improves the quality of the finished steel. In the unit ladle-furnace No 4, filters were cleaned and replaced, preventing the emission of dust into the atmosphere.

Blast furnace No 1 was also repaired. Its capacity is more than 1.5 million tons of pig iron per year. At the blast furnace, the charging device was replaced, which is located at a height of 45 meters. With its help, ore is loaded for further smelting.
