The Kametstal plant of the Metinvest mining and metallurgical group (Kamensk, Dnipropetrovsk region) has begun a series of major repairs of its main rolling equipment under the 2025 program.
According to the company, the first to undergo major renovation was the pipe mill (PM), which produces SVP-27 mine props and large-diameter grinding balls.
It is specified that at the main stage of the overhaul, the efforts of specialists from the metallurgical equipment repair shop and the equipment repair shop are focused on work to upgrade the power, in particular electrical and mechanical, equipment of key large-scale sections, which can only be repaired during a complete and prolonged shutdown of the mill.
Thus, in the rolling mill section, the manipulator lines are being upgraded, the electrical panels of the heating furnaces and the guide bushings of the 900 mill are being replaced. A thorough inspection of the units is being carried out, with all necessary repair operations being performed on the first, second, and third 750 mills. On the roller table field of the rolling mill, to ensure the stability of the rolling movement, the bearings on the rollers and the rollers themselves, worn out due to prolonged operation, are being replaced.
Another important task is to replace a section of the water supply pipeline, which will create an additional backup supply for uninterrupted water supply for the technological needs of the pipe preparation section.
Rolling mill employees, in turn, are cleaning the hydraulic tunnel, removing accumulated scale from the communication structure for technical water drainage.
“This is an important overhaul for the shop and the entire enterprise, aimed primarily at improving the reliability of the pipe mill equipment, which produces strategic SVP-27 profile rolled products for miners. The section is also an important link in the production of billets for large-diameter grinding balls, a product in high demand that is produced on the shop’s ball rolling mills,” the company said in a statement.
Kametstal is part of the Metinvest Group.
