Russian steel giant PJSC Severstal has begun the hot trial phase of a new arc furnace No DSP-1 at the Cherepovets Metallurgical Plant site. Danieli was the supplier of basic engineering and main process equipment. The unit, unique for the Russian metallurgy, with a capacity of 1.3 million tonnes per year, combines the capabilities of an electric arc furnace and a small volume converter. DSP-1 is capable of operating both without liquid iron and with its increased consumption (85% - cast iron, 15% - scrap). The steel smelting process in the main mode of the furnace operation is provided by powerful injectors for supplying oxygen and a supersonic lance. The new equipment in the steelmaking industry will make it possible to process additional volumes of molten iron from blast furnace No 3, which was blown in in December 2020. One of the next steps for the development of steelmaking capacities is the reconstruction of a slab mill of electric steel. The DSP-1 complex includes a modern waste gas cleaning system equipped with a water-cooled gas duct, a needle cooler and a bag filter. The new waste gas cleaning system is designed to ensure compliance with modern environmental standards for emissions of pollutants into the air of no more than 10 mg per cubic meter and compliance with maximum permissible concentrations of harmful substances at workplaces.
