| Abstract: | A set of low-cost energy-efficient solutions for electric arc furnaces (EAF) of a foundry class is proposed: ‘deep’ bath, water-cooled panels with a spatial structure, a system of dispersed aspiration. Numerical simulations of thermal operation and gas-dynamics for 3-ton EAF in conditions of long downtime show the possibility of reduction energy consumption by 6.5–9%, fugitive emissions by 2 times, melting dust removal from the EAF by 19% and significant lowering of specific refractory and electrodes expenditure. |
| Description: | In the foundries of machine-building plants an electric arc furnaces(EAF) with a capacity of 3–6 tons are widely used. Low capacity of transformer, power-consuming classical technology, inefficient aspiration system and long (up to 24 hours and more) downtime, predetermine their low energy efficiency in comparison with the EAF of a ‘large’ metallurgy. An urgent task is the development of low-cost energy-efficient solutions for the foundry class EAF modernization. Proposed solutions are justified by methods of numerical modeling. |
