Ilyich Iron & Steel Works of Mariupol Completes Major Converter Overhaul
The major overhaul included the full dismantling and further inspection and installation of all key units and mechanisms of Converter #3 and its heat recovery boiler. In order to optimize repairs and save time, for the following major units were assembled: steel structures and equipment with a weight of 1,000 tons were lifted with jacks, installed on special-purpose truck platforms, brought to and taken out of the installation site. The metal used in the heat recovery boiler’s pipes underwent a control analysis. To improve steelmakers' working conditions and ensure safety, an additional housing was installed over the converter, more efficient supply schemes for ferroalloys and auxiliary materials were developed, and an oil supply control system via special-purpose converter bearings was implemented.
The environmental impact of refurbishing the cleaning equipment in the steelmaking unit was one of the most important parts of the overhaul. Workers cleaned all of the units within the gas purification system and its ducts from process deposits and adjusted the devices. This will bring emissions to their designed level and reduce them in the future.
The overhaul of Converter #3 will increase the time between repairs in the steelmaking unit to ten years.
Ilyich Iron & Steel Works of Mariupol’s strategic modernization program also envisages upgrades to key process equipment, industrial buildings and structures, and transportation in 2013. The plant has invested about UAH 350 million in the program.
Andrey Shishatsky, chairman of the Donetsk Regional State Administration, and Yuriy Khotlubey, mayor of Mariupol, took part in commissioning ceremony of Converter #3, together with Yuriy Zinchenko, Ilyich Iron & Steel Works of Mariupol’s general director.
Zinchenko thanked all of the 500 plant's workers who participated in the overhaul.
"Upgrading the manufacturing capacity of our plant is one of the key factors that ensures a stable and steady presence in markets and where we can show our competitive advantage compared to other steel products manufacturers,” Zinchenko said. “This is very important today. That is why clear and timely major overhauls, as with the converter shop, allow the plant's workers to take on complicated and responsible tasks to improve the safety of process and power equipment, reduce production costs and improve the quality of the products that we manufacture."
Shishatsky said, "Despite the crisis, the Ilyich plant is becoming stronger. This is your future, because the plant has a clear development strategy including technological progress and an environmental component. The plant's employees have a good social package, and this is the basis for policy by Rinat Akhmetov, the main shareholder of Metinvest Group – a person whose words and actions mean the same."
Khotlubey said, "It is possible to implement such projects during a very severe economic crisis only within Metinvest, a large holding. It has the ability to find funds for upgrading and modernization to achieve the highest production standards."
