October 13, 2016

Regular overhaul program of 2016 was completed at Kolpino area of Severstal company, where Izhora pipe mill (ITZ) and slitting lines shop (LPTS) of roll plant production of Cherepovets Steel Mill (part of Severstal Russian Steel division) are located. Autumn overhaul in LPTS was the final activity that  ended in the beginning of October.

Design objectives of reheat and continuous furnaces, four-high stands of  broad-strip mill 5000, traversing devices and motor room engines were repaired during spring and autumn maintenance activities in slitting lines shop. Other works were performed as well, including reconstruction of cooling system of  rolls and reheat furnace No.1 automatics; additional prior-to-stand scale flushing collector was incorporated.

Spring and autumn overhauls were performed at Izhora pipe mill. Overhauls involved main equipment of electric-weld pipe workshop (TESTS) and finishing plant and pipe shipment workshop (TSPiOT). For instance, exhaust pipeline for  adhesion measurement was built during TSPiOT repair. It improved tarnishing technology. TESTS specialists modernized the bottom beam of pipe-forming press: special rolls with shock absorbing inserts were installed. The project provides increase in productivity of the machine, as well as further improvement of  product quality.

Employees of Promservis center (repair subdivision of Severstal Russian Steel division), representatives of plant area and contracting agencies took  part in realization of overhaul program.
