Lining repair of BF5 at PAO «Severstal» (Cherepovets, Russia)
In late April 2021 Refracon carried out the lining repair of the stack of BF 5 at Cherepovets Metallurgical Plant PAO “Severstal”.
The aim of the project was to restore the old lining at the top of the blast furnace stack. To complete this project, Refracon used state-of-the-art robotic shotcreting equipment.
What makes robotic shotcreting technology unique is that the intervention is carried out without admitting repair personnel into the blast furnace interior, thus significantly reducing furnace downtime and the cost of preparing and carrying out repairs.
Modern refractory materials specially developed by Seven Refractories were used during this project. In total, over 100 tonnes of monolith refractory were applied.
