Metinvest Group’s KAMETSTAL, a steelmaking plant at Dnipro Metallurgical Plant (DMK, Kamenskoye, Dnipro Oblast), has completed a 50-day overhaul of its main air separation unit (ASU).
According to the company, on New Year’s Eve, the plant’s power engineers resumed operation of the air handling unit, and the overhaul of the AKAR-40/35 was one of the largest overhauls performed at the plant under the 2024 program.
It was specified that after completion of the scheduled repair work, specialists began preparatory pre-start-up operations in mid-December. High-temperature regeneration of the adsorbent was performed after its complete replacement. As part of the overhaul, 68 tons of zeolite and 33.6 tons of aluminum oxide, highly dispersed materials for air purification from moisture and carbon dioxide, which negatively affect the performance and quality of air distribution, were loaded into the cleaned and repaired adsorbers.
On December 26, the first post-repair oxygen was supplied to the collector after completion of the preparatory stages required by the technology – heating of the unit and cooling of the vessels and apparatus of the plant. The passport characteristics of the AKar-40/35 were restored and it started operating, after which the power engineers gradually put the AKar-30 units into reserve, which replaced the main unit during its overhaul. Tests conducted on December 28 confirmed the unit’s nameplate capacity of 40 thousand cubic meters per hour of nitrogen and 35 thousand cubic meters per hour of oxygen.
“The unit is now operating in the set mode, steadily supplying air separation products to the steelmaking process. The unit’s load varies according to the needs of the production process. Thanks to the well-established cooperation between the OCC specialists and their colleagues from the blast furnace and converter shops, we determine the optimal production mode on a daily basis without unproductive losses of oxygen produced, which makes it possible to increase the efficiency of the repaired unit and the shop as a whole,” explained Vyacheslav Grevtsev, head of the oxygen compressor shop, as quoted in the statement.
“KAMETSTAL was established on the basis of Dnipro Coke Plant and Centralized Steel Works of Dnipro Metallurgical Plant.
According to the 2020 report of Metinvest Group’s parent company, Metinvest B.V. (Netherlands) owned 100% of the shares in DCCP.
Dniprovsky Iron and Steel Works (DMK, Kamianske, Dnipropetrovsk region), part of the Industrial Union of Donbas (ISD) corporation, in January-February of this year, increased the production of general rolled products, according to recent data, by 3% compared to the same period last year, to 415,000 tonnes.
As the representative of the enterprise told Interfax-Ukraine, during this period the plant increased steel production by 4.5%, to 420,000 tonnes and kept the production of cast iron at the level of 375,000 tonnes.

In turn, the economic planning department of the plant said that in February 2021 it reduced the production of commercial metal products to the level of 192,813 tonnes.
“Last month, the target was fulfilled only in the rolling shop. Sinter, blast furnaces and converters worked in the negative indicator,” according to the company’s information.
At the same time, it is said that the sinter shop produced 284,736 tonnes of sinter, which is 91.9% of the target. In addition, with the target of 181,906 tonnes of cast iron, 171,040 tonnes were produced in February, which is 6% less.
The target for steel production was fulfilled by 96.2% – 193,280 tonnes were produced, which is 7,702 tonnes less than the target. In the total steel production, the amount of commercial steel amounted to 129,929 tonnes, while the target was 138,017 tonnes.
The total output of rolled products for the last month was 70,065 tonnes (3,175 tonnes to the target).
In February, the plant shipped 195,707 tonnes of commercial metal products to customers, which is 3.8% less than the established target.
As reported, the plant in 2020 increased the production of general rolled products by 13.3% compared to the previous year, to 2.54 million tonnes, steel by 15.2%, to 2.56 million tonnes, cast iron by 19.2%, to 2.36 million tonnes, and agglomerate by 40.2%, to 4.06 million tonnes.
Dniprovsky Iron and Steel Works specializes in the production of cast iron, steel, rolled products and consumer goods.
The company is controlled by the ISD corporation which was founded in 1995. It is an integrated holding company that owns or manages stakes in mining and metals enterprises.
