The Kametstal plant of the Metinvest mining and metallurgical group, created at the facilities of the Dneprovsky Iron and Steel Works (Kamenskoye, Dnepropetrovsk region), reduced power consumption in the converter department by 6 kWh per ton of steel produced from 27.4 to 21.4 kWh/t of melts.
According to the company’s information, in particular, the operating time was halved unloading rotors of converter smoke exhausters. Work is organized on 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 energy consumption.
Converter gases on both operating converters. According to the investment project, frequency converters and modern controllers from Schneider were installed on TsN-1 and TsN-2. This makes it possible to automatically unload pumping equipment in accordance with the steelmaking process and thus minimize its energy consumption between blowdowns in the converter. At the same time, an algorithm for automatically controlling the heating process has been developed and improved.metal in a ladle furnace installation by selecting the best combination of degrees and speed of heating itself.
