The Kametstal plant of the Metinvest mining and Metallurgical Group, created at the facilities of the Dnipro Metallurgical Plant (Kamenskoye, Dnipropetrovsk region), reduced power consumption in the converter unit by 6 kWh per ton of steel produced from 27.4 to 21.4 kWh/ton of smelts.
According to the company's information, in particular, the unloading time of the rotors of the converter smoke pumps has been halved. The work is organized according to the principle of alternate use of each of the two converters, which makes it possible to turn off equipment not involved in the current melting and minimize idling, thus ensuring a systemic reduction in power consumption.
Converter gases on both operating converters. According to the investment project, frequency converters and modern Schneider controllers were installed on TSN-1 and TSN-2. This allows the pumping equipment to be automatically unloaded in accordance with the technological process of steel smelting and thus minimize its electricity consumption between purges in the converter. At the same time, the algorithm for automatic control of the metal heating process at the furnace-ladle installation has been developed and improved by selecting the best combination of degrees and speed of heating itself. It is part of the Metinvest Group.
