PrJSC Dniprovsky Metallurgical Plant (DMZ, formerly Evraz-DMZ), a member of DCH Steel of the DCH group of businessman Oleksandr Yaroslavsky, has completed the first stage of overhaul of coke oven battery No. 4, which will reduce emissions of air pollutants.
According to the company’s press release on Thursday, the total investment is about UAH 170 million.
As part of the investment project, 20 coking chambers were repaired at the DMZ coke-chemical site. Repaired furnaces do not lose coke oven gas – all of it goes for treatment. Due to the sealing of the refractory masonry, the elimination of leaks into the heating system from the coking chambers and more complete combustion of gas in verticals, emissions of pollutants will decrease.
The press service also said that the excess of coke oven gas, which may be formed during the commissioning period, will be sent to the afterburner, the work of which is fully consistent with the technological process. The repair of the rest of the coking chambers will continue at the operating battery, and it is planned to complete it by the end of the year.
“DMZ is systematically engaged in the modernization of fixed assets at the coke-chemical site. In addition to the overhaul of coke oven battery No. 4, this year, ceramic surfacing is being carried out at coke oven battery No. 1 and coke oven battery No. 2 with sealing of heating walls. In general, this will increase the efficiency of the furnaces and significantly reduce the burden on the environment,” Director General of the DMZ Vitaliy Bash said.
At the same time, it is recalled that since 2016, DMZ has invested UAH 475 million in environmental programs. During this time, the company has reduced air emissions by almost 25%. Now the enterprise has an investment program in the amount of $400 million, aimed at modernizing production facilities and reducing the burden on the environment.
DMZ specializes in the production of steel, cast iron, rolled products and products from them.
PrJSC Dniprovsky Metallurgical Plant (DMZ, formerly Evraz-DMZ), part of DCH Steel from DCH Group of businessman Oleksandr Yaroslavsky, in January-June this year increased the output of finished rolled products 12 times compared to the same period last year – up to 117,500 tonnes from 10,000 tonnes. According to the company, in January-June of this year, DMZ also increased the production of pig iron to 151,400 tonnes from 18,000 tonnes (an increase of 8.4 times) and steel up to 144,000 tonnes from 13,000 tonnes (11 times more). Coke production increased by 5.3% compared to the same period last year, to 242,200 tonnes.
DMZ in June 2021 increased the production of pig iron in comparison with the same period last year by 38%, to 24,700 tonnes, steel – by 102.2%, to 27,100 tonnes, rolled products – by 100.9%, up to 21,500 tonnes. Coke production remained at the level of 40,000 tonnes.
The metallurgical workshops of the DMZ resumed work after a downtime in May-June 2020, before that, for seven months, the plant produced only coke-chemical processing products.
The plant specializes in production of steel, cast iron, rolled products and products from them. In 2020, the plant reduced steel output by 66% compared to 2019 – to 175,000 tonnes, pig iron – by 67.3%, to 160,000 tonnes, rolled products by 68.4%, to 140,000 tonnes.
On March 1, 2018, DCH Group signed a purchase agreement of Evraz DMZ.
PrJSC Dniprovsky Metallurgical Plant (DMZ, formerly Evraz-DMZ), a member of DCH Steel of DCH Group of businessman Oleksandr Yaroslavsky, will allocate more than UAH 15 million for the implementation of the energy saving program in 2020-2021.
According to a press release from the company, major repairs were carried out last year on the combustion plugs of excess blast furnace and coke oven gas, thus avoiding energy leaks. To date, the work on replacing outdoor lighting on the territory of the enterprise has been practically completed.
In rolling shop No. 2, seven frequency converters were installed on the fans for blowing off the electric motors of stands Nos. 1-8, about 70 lamps were replaced with energy saving ones in three spans. The lighting on conveyors S-4 and U-1 of the coke plant was also replaced.
“The modernization of lighting will significantly reduce energy consumption. In addition, working conditions will improve, as the illumination from LED lamps is much higher,” the press release said.
The plant specializes in production of steel, pig iron, rolled products and coke.
On March 1, 2018, DCH Group signed an agreement on the purchase of Dniprovsky Metallurgical Plant from Evraz.
The DCH Group, uniting assets of Ukrainian businessman Oleksandr Yaroslavsky, under a strategy of increasing effectiveness of the mining and metal business has created DCH Steel, which will manage the respective assets: Dniprovsky Metallurgical Combine (DMZ, Dnipro) and Sukha Balka ore mining enterprise (Kryvy Rih).
According to the information on the official website of DCH, the essence of the transformation is to optimally build a management system for mining and metal enterprises at the stage of implementing large-scale investment projects.
According to DCH, Yaroslavsky plans to invest from $150 million to $200 million in his mining and metallurgical business over the next five years. Owning to these investments, in particular, the blast furnace stock of coke-chemical production will be restored at the DMZ and a continuous casting machine will be built, and at Sukha Balka it is planned to organize a processing plant, to develop ore deposit at deeper levels, and to upgrade equipment.
“In the process of gradual vertical integration, the production chain ore mining-enrichment-agglomeration-smelting of iron will be formed,” the group said.
According to the press release, at the level of DCH Steel, general management functions will be centralized, and manufacturing companies will focus their efforts on production and improvement of technology. The expected results of optimizing the management of the mining and metallurgical business of the DCH are to eliminate dependence on external supplies of sinter, to ensure a positive synergy of the activities of the DMZ and the mining enterprise, which should increase competitiveness and sustainability, as well as improve financial performance.
