The Russian steel company Severstal has completed hot testing on the upgraded slitting line No. 10 of the Cherepovets Metallurgical Combine (CherMK) as part of a modernization project launched in 2024 to improve productivity, product quality and equipment reliability.
The modernization, which cost more than 1 billion rubles, included the replacement of about 80 percent of the line's equipment, including rotary shears, a tensioner station, an oiler and a winding machine. The new rotary shears will allow the line to produce a wider range of cold-rolled products in both width and thickness, with width tolerances up to 0.5 mm, and will also allow the winding of rolls with a diameter of 508 mm.
During the hot tests, the unit produced more than 6,000 tons of cold-rolled coils and demonstrated the necessary operating parameters, which allowed Severstal to begin warranty testing. After the upgraded line reaches its design capacity, the annual production volume of complex and specialized products for radiators, industrial racks, household appliances, automotive components, and small-diameter pipes is expected to increase by 15,000 tons.
