The completely modernized hot rolling mill 2500 of PJSC MMK is among the most modern and high-performance in the world.A large-scale reconstruction of mill 2500 at Rolling Mill No 4 made it possible to expand the size and grade range of the mill. The quality of manufactured products has significantly improved, and the production capacity of the unit has increased to 5.2 million tonnes of rolled metal per year. It is a highly automated unit whose products meet the highest international standards. Demand for the products of the mill is confirmed by a systematic increase in the utilization of its capacities.In November 2020, for the reconstruction of hot-rolling mill 2500, PJSC MMK was recognized as the winner of the Main Event of 2020 in the Metallurgy of Russia award.
