A full-cycle metallurgical giant. Krivoy Rog ore plus Donetsk coal - rolled metal products at the output, including axles for railway wagons. There was (I don't know now) a carriage building plant named after Gazeta Pravda on the territory. The whole city lived by the rhythm of these factories. Specialists were trained by the Dneprodzerzhinsk Industrial Institute named after M. I. Arsenichev and the Metallurgical College. In the 70s, up to 30 thousand workers worked at the plant.
