Metinvest Group’s KAMETSTAL, a steelmaking plant at Dnipro Metallurgical Plant (DMK, Kamenskoye, Dnipro Oblast), replaced outdated electrical equipment in the company’s coke oven shop to stabilize the operation of coke oven battery No. 5 and improve energy efficiency.
According to the company, distribution substation No. 55 was modernized in the coke shop as part of this year’s investment program, which made it possible to demonstrate higher reliability of power supply to coke oven battery No. 5.
It is also specified that the main objective of the investment project is to completely replace the outdated contact equipment with modern automatic German-made equipment. As part of the modernization, new circuit breakers with current and thermal protection were installed, as well as new electromagnetic starters instead of contactors. In total, four sections of the substation have been upgraded, and the old equipment at RP-55 has already been decommissioned.
The new equipment with a high level of automation allows online monitoring of the circuit breakers. The sections are equipped with on-off visualization elements, which allows the electrician on duty to check the operation of each circuit breaker faster and more accurately.
Alexander Shulzhenko, an electrician at Kametstal’s coke shop, stated that the three months of operation of the new equipment have made it possible to improve the reliability of the battery’s power supply and avoid downtime of the main equipment related to the reliability of power supply.
“Also, thanks to the metering system introduced as part of the modernization, which allows us to track electricity consumption online on a computer, we can now analyze the electricity consumption of each consumer throughout the day. This analysis has improved the accuracy of electricity consumption planning, and we plan to develop energy-efficient measures to reduce electricity consumption based on the analytical findings,” said Shulzhenko.
“Kametstal was established on the basis of Dnipro Coke Plant and Central Iron and 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.
