INVESTIGATION OF THE INFLUENCE OF ELECTRIC ARC PARAMETERS ON ITS ENERGY MATTER
The paper considers the main ways to improve the technology of electric arc melting. The dependences of the influence of the main technological parameters of melting and the composition of charge materials on the energy efficiency of the arc furnace operation have been revealed. The obtained dependences of the influence of the share of liquid iron and oxidized pellets in the metal charge, the consumption of oxygen, lime with dolomite, and the quality of coke make it possible to determine the rational parameters for conducting melting with the aim of reducing the specific consumption of electricity. Recommendations for improving the energy regime of electric arc melting have been developed, which make it possible to achieve a reduction in specific power consumption and to achieve rational parameters of smelting in an arc steel-making furnace.
