After 15 years of operation, SMS group Technical Service replaced the converter tilting drives of Tŕinecké Železárny in two steps during the regular annual shutdowns. In this interview, René Dzivý, Head of Maintenance Steel Plant of Tŕinecké Železárny summarizes the project in his own words.
In 2003 Tŕinecké Železárny (TZ) ordered at SMS group GmbH two new vessels with suspension systems, trunnion rings and two new tilting drives for their BOF shop. This modernization enlarged the capacity and reliability of the steel plant significant. After 15 years of operation, the bull gears of the main gearbox showed smaller wear indications and TZ decided to check and replace both tilting drives for keeping the availability and reliability at highest level. In 2018 and 2019 both tilting drives were replaced during regular shutdowns.
Třinecké Železárny has been a successor of the long tradition of metallurgical production in Těšín Silesia (Czech Republic) for more than 180 years. Třinecké Železárny together with its sole shareholder Moravia Steel and almost thirty subsidiaries rank among the most significant industrial groups in Central Europe. In the last ten years, Třinecké Železárny has been the largest producer of crude steel in the Czech Republic. Annual production reaches around 2.5 million tonnes of steel and the main product portfolio consists of long rolled products.
