The Cherepovets Iron and Steel Works (CherMK, part of the Severstal Russian Steel division) is bringing a new electric arc furnace to a high iron consumption rate of 75-85%. This is one of the most important technological features of the unit, which ensures the efficiency of its operation.
To reach the specified modes, a series of experimental heats were carried out. The production process when the furnace is operating with a high proportion of cast iron is provided by powerful injectors and a supersonic lance. In addition, DSP-1 is equipped with a special tilting device, thanks to which the cast iron is poured in automatic mode. It combines the capabilities of an electric arc furnace and a small volume converter.
The technological process at DSP-1 is carried out in accordance with the requirements and norms of environmental legislation. The gas cleaning and aspiration equipment of the unit complies with which allows to achieve purification of waste gases and other process emissions up to the level of compliance with modern environmental standards (10 mg /m3) and to achieve standard indicators of maximum permissible concentrations at workplaces.
